  • Pictogram voting comment.svg Comment Nothing to add :) This similar to the properties for Chinese names. --- Jura 12:12, 10 November 2015 (UTC)
  • Pictogram voting question.svg Question What is the difference between a praenomen and a given name, and between a cognomen and a surname? Also, is there a more generic version of nomen that might be usable? (Clan name, maybe?) If avoidable, I think we should try to have as few culture-specific name properties as possible. --Yair rand (talk) 03:04, 11 November 2015 (UTC)
    • From a Wikidata perspective, it would be that praenomen link to items for praenomen, P735 to items for given names; P734 links to whatever it links and cognomen to items for cognomen (and nomen to items for gens). I added links to related categories and lists to the proposal. The article linked in the proposal explains how Roman naming as well as the function and selection of various parts evolved .. at some point, one or the other could be considered similar to given names and family names today, but later or earlier not. One of their characteristics is their designation as praenomen and cognomen.
      It's possible to use the same property for clans and Roman gens, but I don't think it helps when adding or checking values. What do you think? --- Jura 13:25, 11 November 2015 (UTC)
  • Pictogram voting comment.svg Comment I changed the second proposal to "Roman nomen gentilicium". This should avoid potential issues with other nomen that are not for the gens. @Filceolaire, Jonathan Groß: is this ok with you? Potentially, we might need an other property for names that are not any of the four. Shall we add this now as well? --- Jura 07:44, 13 November 2015 (UTC)

    • @Jura1: My opposition has nothing to do with the proposal being in a particular language. Mbch331 was asking for a translation (a perfectly valid request). My opposition is that there is no valid example or datatype listed. Until they are provided, this proposal cannot be properly considered and so until it can be, I oppose its creation. Josh Baumgartner (talk) 22:42, 6 November 2015 (UTC)
      • Well, you opposed it because you don't understand it as it's being written in a language you apparently don't understand. --- Jura 00:49, 7 November 2015 (UTC)
        • @Jura1: The example is (as of this edit) Universe (Q1)Earth (Q2), which is not in Russian, and it clearly says "invalid datatype (not in Module:i18n/datatype)", also not in Russian, so please stop claiming your own reasons why I oppose this, and instead refer to what I wrote above. We need to know how a proposed property is going to be implemented before we can complete a discussion of its merits. Josh Baumgartner (talk) 21:52, 16 November 2015 (UTC)
          • If you set your interface to Russian and look at the form to copy-and-paste, you will notice that he did choose a datatype. We know well that the formatting of the template is quirky and doesn't work well. This is probably the reason why we ask property creators to complete it in if it wasn't done during the proposal process. Not sure if we really should expect a ru-only user to write you a translation in English .. Logically, we would need to ask him that in Russian. What do you think? --- Jura 11:46, 17 November 2015 (UTC)

I think it is better to keep it clearly a string with the prefix, even if there's a slight redundancy there. ArthurPSmith (talk) 14:54, 24 November 2015 (UTC)

Once this identifier property is in place I was planning to put together a "bot" import to wikidata from the GRID dump file; however, I'm not sure of the best way to correlate records. It looks like only about 1/4 of your entries have ISNI ids - so that would be a start, but fairly incomplete. A similar number seem to have wikipedia URL's that should be possible to link through to wikidata id's. For the rest it would probably have to be something based on name and address and I can see that running into challenges with mismatches or overeager matching. Have you thought about adding wikidata ID's to the grid dump at some point so the link can be made more reliably? ArthurPSmith (talk) 14:59, 14 December 2015 (UTC)

Motivation

The hanja version of the name is included in infobox/sidebar templates in many articles about Korean topics (e.g. in the infobox on en:Pyongyang, just below the infobox on en:Park_Geun-hye), in brackets after the name in the opening sentence (e.g. ko: 평양직할시) or as a column in tables (e.g. en:List of cities in South Korea). - Nikki (talk) 11:29, 26 June 2015 (UTC)

Discussion
Symbol oppose vote.svg Oppose use as proposed but Symbol support vote.svg Support as a qualifier to string and text properties in other languages. The hanja version of the name for Pyongyang should be given by official name (P1448) and/or native label (P1705) and/or name in native language (P1559), not by this property (but use the "Romanisation" qualifier to give the Latin script version of each of these names). This property could however be used to give the hanja name for "London" in a qualifier to the official name (P1448) property for use in Korean language infoboxes. I have changed the example as my version of this property. Nikki please check and confirm you copy. Filceolaire (talk) 01:01, 27 June 2015 (UTC)
@Filceolaire: Your example is incorrect, that's not en:Hanja, it's en:Hangul (the way Korean is normally written). This property would be very similar to name in kana (P1814) (which you supported without requiring it to only be used as a qualifier - has something changed since then?) - like Japanese is not primarily written in kana, Korean is not normally primarily written in hanja, and like kana is often included in name templates, in brackets in opening sentences, etc, hanja is too, so it should be allowed anywhere that name in kana (P1814) is allowed, i.e. as a qualifier if it's the hanja version of a Korean name in a statement using properties like native label (P1705), name in native language (P1559) and official name (P1448) or as its own statement if it refers to the hanja version of a Korean label (since labels can't have qualifiers themselves). - Nikki (talk) 06:40, 27 June 2015 (UTC)
You raise a good point Nikki. Thinking about it some more. There is a difference between a property called "name in Hanja" and a property called "hanja".
"name in Hanja" could be a property specifically for names. It is similar to all the other multiple "name" properties we have and it can be used as a primary property just like official name (P1448), native label (P1705) or name in native language (P1559). This is based on the assumption that if an item has multiple names then the hanja name just another, additional name independent of the other names.
If, on the other hand, each of the multiple names needs a it's own hanja version then it seems the "hanja" is an alternative way of writing those names rather than being a separate name (and should be used as a qualifier). Which case applies? Filceolaire (talk) 02:31, 28 June 2015 (UTC)
@Nikki:? Joe Filceolaire (talk) 11:50, 18 September 2015 (UTC)
@Filceolaire: I feel like I have already explained it as best I can so I don't really know how to continue this discussion without getting frustrated by going round in circles and repeating myself. If you're still opposed to the property, then we might as well reject it and revisit it when people who have experience with Korean are willing to contribute to the discussion. Alternatively, if changing the label to "name in hanja" makes it acceptable, let's do that. - Nikki (talk) 13:01, 18 September 2015 (UTC)
I'm sorry Nikki. I didn't mean to harass you. I've done some more reading and I think I understand the difference now. Hanja is the name written using 'chinese' characters. I think a better way to handle this is to have two different values for the various monolingual text proeprties - one in hangul and one in hanja with different codes to indicate if it is 'ko-hanja', or 'ko-hangul'. Unfortunately this is not allowed at the moment (I tried something like this on Park Geun-hye (Q138048) but I think you had better check I got it right). There are bugs on manifest for this T74590 and T95286. I'm afraid I do not think that a separate property like this is the way to go so I will Symbol oppose vote.svg Oppose this proposal.

Motivation

Property might be useful for automatic generating readable descriptions from statements if object name is not available in any readable script in user language. This might be a standard way to provide transliteration or transcription of the name between many languages. The examples above are biased because they show romanization only, but other direction is also possible. Unfortunately I am not able to provide any such example. Paweł Ziemian (talk) 17:50, 27 June 2015 (UTC)

Discussion
We have some romanisation-properties now, like "pinyin transliteration (P1721)", so there is maybe a way to solve even other systems. But if we are to follow the pattern here, we need one property for each kind of romanisation? -- Innocent bystander (talk) 18:12, 27 June 2015 (UTC)
If the conversion is some kind of international standard like Hepburn romanization (Q667558) or ISO 9 (Q913336) it can be promoted to separate property. However, there are cases where such translation is country/language specific and generating N×N - N (country/language) properties is ridiculous. One generic property should serve for all relatively rarely used cases. If some of them became popular it can be always promoted later to dedicated property and converted by bot. Paweł Ziemian (talk) 19:10, 27 June 2015 (UTC)
One item can have multiple names, even in one language (via aliases). To be clear as to which name you are transliterating this property needs to be a qualifier to one of the other name properties. Unfortunately if this property is a qualifier then it can't have it's own qualifiers to tell you which transliteration system was used. This indicates that we need multiple properties - one for each transliteration system. Fortunately we don't need to transliterate all names since for most items, in most languages, the transliterated name will be in the label. I think. Filceolaire (talk) 03:00, 28 June 2015 (UTC)
I am not so sure about that! The Swedish transcription of for example Russian names are not always in the label, but rather the German or English, since those transcriptions are sometimes more spread in common media. And I would prefer to see a monolingual datatype in those cases, i.e. when the transcription is langauage dependant. -- Innocent bystander (talk) 10:56, 28 June 2015 (UTC)
It is not unusual that there exist a few methods for transcription from one language to another. I agree with argument that it should be a qualifier, but with requirement for auxiliary and mandatory qualifier it is impossible to implement this. This is the weakness point in my proposal. I think I should withdraw the proposal and introduce set of new proposals for specific transliterations, what was mentioned above. Paweł Ziemian (talk) 13:33, 28 June 2015 (UTC)

Symbol support vote.svg Support as a qualifier (for properties such as titles or birth name) or property (for name items) when there is no more specific property available or if we just know it's transliterated, but we don't know for sure if it corresponds to a specific version of a transliteration standard. --- Jura 13:49, 19 December 2015 (UTC)
So your idea is to drop the name of the transliteration standard? I'm not sure if in that case anyone will be able to reuse the claims as one will not even know if it's a translitaration to latin script or maybe a transliteration from cyrillc to Georgian script. --Pasleim (talk) 22:58, 19 December 2015 (UTC)
Isn't the script defined with the characters used in the string? What alternatives do you suggest? --- Jura 13:43, 21 December 2015 (UTC)
Transliteration depends not only on script, but also on language. The same Cyrillic name transliterates differently into French/German/English. --Infovarius (talk) 15:06, 21 December 2015 (UTC)
That is probably good alternate proposal. I suppose we could implement both. Would you do the property request? --- Jura 13:28, 22 December 2015 (UTC)

    Depends on how much inference you want to do. There are some units (inches) that convert nicely (thanks, Queen of England) to SI, and some (pounds-force) that don't. --Izno (talk) 01:26, 1 September 2015 (UTC)

    A more general conversion property might be better anyway though i.e. to get feet to yards to miles. I don't see a reason for the notion of "standard" vice not standard. Maybe the conversion property could have a qualifier of "unit standard" or perhaps use the "specified by" property as a qualifier. Actually, I like that idea. --Izno (talk) 02:32, 7 September 2015 (UTC)
  • An alternative would be to set a goal of always expressing quantities in a chosen set of SI units, and then having a property "source units" which preserve how the quantity was written in the source that supports the value. Ideally such a property would be attached to the reference, since several different references might express the same value in different units. If someone sets the quantity in an undesired unit, someone can always fix it later and preserve the source value with the new property. Jc3s5h (talk) 13:22, 18 September 2015 (UTC)

This property should be used for measurement units to convert them to S.I. units so every units for measuring length would have this property for converting to 'meter'. Every unit for measuring energy (from kilotons of TNT to barrels of oil) would use this property to give the equivalent in 'Joule'. This is the crucial middle man that will let us compare any measurements. I suggest we rename this property as 'conversion to SI unit'.
For other conversions just use the general properties we already defined so "foot" is <length:12(unit=inch)>and <conversion to SI unit:0.3048(unit=meter)>. Joe Filceolaire (talk) 18:53, 12 October 2015 (UTC)
  • Symbol support vote.svg Support, but I would broaden the use to simply 'conversion to alternate units'.

Oppose with this name. James: A property called "Time Interval" is too likely to be abused for things that need a start time and an end time. Can we change the label to Duration? Joe Filceolaire (talk) 18:34, 19 October 2015 (UTC)
"Duration" would be a good label. James Hare (NIOSH) (talk) 14:59, 21 October 2015 (UTC)

Snipre, I take it that that property can be used to describe durations other than those of timed media? James Hare (NIOSH) (talk) 13:59, 29 October 2015 (UTC)
At its creation this property was called "duration" but some contributors modified it for their own purpose. We should see if this is a problem to keep a more general definition for this property. Snipre (talk) 15:42, 29 October 2015 (UTC)
@Snipre, James Hare (NIOSH): I can see extending the use of duration (P2047) for the duration of tracks on LPs but using it for exposure limits seems a step too far so I would be in favour of a separate property for this. The question then is if we have a specialist property for 'exposure limit time intervals' or if we have a generic 'duration' property used for exposure limits and other places where we need a qualifier to specify duration (then duration (P2047) probably gets classified as a 'subproperty of' such a generic property, along with some specialist property for race times). Personally I would go with using a generic 'duration' property for exposure limits since it is a qualifier to the important info - the dose in mg. Joe Filceolaire (talk) 22:12, 29 October 2015 (UTC)
@Filceolaire: Please look at the translated labels for duration (P2047): Dauer in German, duración in Spanish, durata in Italian. Only English has a special definition for this property. I can understand to have specific properties when you use the generic property several times in the same item and if you need then to use qualifiers to distinguish who is who. I can understand specific properties if you want to track errors by using a tight range for values or only one unit. But in the current property this is not the case. Right now I asked the extension of the application of duration (P2047) to all field using the label "duration"~on the talk page of duration (P2047). I propose to discuss this case there. Snipre (talk) 12:40, 2 November 2015 (UTC)

Thanks to some talented people the Internet Archive has made some of these games playable in the browser such as Targ which is free for non-commercial use.

GeoNames feature code

Description Feature class or feature code of a place type in GeoNames
Represents GeoNames (Q830106)
Data type String
Template parameter none
Domain place type
Example lake (Q23397) → "H.LK", pond (Q3253281) → "H.PND"
Format and edit filter validation See statistics link
Source GeoNames ontology, statistics, gsheet dump 2014-07
Motivation

625746 WD items have GeoNames ID (P1566), and 117301 of them don't have instance of (P31). If "GeoNames feature code" is created, these "instance of" can be added automatically. Furthermore, we can use this property to check for agreement with GeoNames. Since GeoNames is dedicated to geo info, I'd trust it more than WD on this aspect. Furthermore, this can be used to compare the GeoNames type hierarchy (which is only 2 levels) to WD's, and add more types to WD. Vladimir Alexiev (talk) 17:22, 16 October 2015 (UTC)

  • Symbol support vote.svg Support Runner1928 (talk) 18:31, 16 October 2015 (UTC)
  • As it is, I think I have to say Symbol oppose vote.svg Oppose, because I have some concerns which make me question how useful it would be:
    • I'm not an expert on licensing, but GeoNames is licensed as CC-BY, which (as far as I understand) means it's incompatible with Wikidata's license and we can't use it to automatically add instance of (P31). The only purpose of adding this seems to be for using GeoNames' data and if we can't do that, there doesn't seem to be any point in spending time adding and maintaining it.
    • I don't think it's clear that it's not designed to be used for individual instances. I can imagine people adding "GeoNames feature code: H.LK" to individual lakes, because it wouldn't seem wrong, the feature code for something which is a lake is indeed "H.LK".
    • I'm also questioning how well we can really map the two. There are a number of differences and how someone wants to handle those really depends on what they're trying to achieve. For example, GeoNames has H.STM which it uses for both streams and rivers. If you want to convert H.STM to a single Wikidata ID (e.g. for adding instance of (P31)), you should probably use watercourse (Q355304) because you can't tell whether it's a stream or river. If you want to find all items which should use H.STM (e.g. to check whether Wikidata's data matches GeoNames), you want river (Q4022) and stream (Q47521) but not watercourse (Q355304), because watercourse (Q355304) is broader than H.STM. It's often more complicated than simply mapping feature codes to items too, for example, A.PCLH, which can be an instance of country (or any of its subclasses) with an end date qualifier, or P.PPLA2, which would be an instance of human settlement (or any of its subclasses) located in a second-level administrative division (or any of its subclasses) which is the capital of the same administrative division it's located in. -- Nikki (talk) 01:12, 19 October 2015 (UTC)
    • @Nikki: All these are good considerations about difficulties, but I don't thin they render the property useless. 1. I'm not saying we can map everything automatically and one-to-one. But we can still do useful checks. Eg H.STM would be mapped to Watercourse, and we can expect all its subclasses to also match H.STM. So if we find a subclass with *another* feature code, that would be an error to flag. 2. Adding a class (instance of) to 117k Wikidata places that don't have it, seems like a good first step, since that's better than no class at all, agree? 3. You're right regarding temporality: Geonames doesn't have historic info (and is missing historic places that are in DBpedia, such as Roman Empire aka Ancient Rome; for the Europeana Food and Drink project we're grafting them into the Geonames place hierarchy). But doing checks for current places is still very useful. 4. PPLA2 can be used not only to check type correspondence, but also to check (or insert!) capital (P36) (in this case, using gn:parentFeatureADM2). --Vladimir Alexiev (talk) 08:13, 26 October 2015 (UTC)
      • 1: Not all subclasses of watercourse are H.STM, only some of them, e.g. canal is a subclass of watercourse here, but the Geonames code is H.CNL - like I said, the best mapping depends on what you want to do with it. 2: Of course I agree that it would be good to add instance of (P31), but where will we get the data from? Geonames is under an incompatible license, so we can't import data from there. 3: I didn't mention anything about temporality, I'm not sure who or what you're responding to there. - Nikki (talk) 14:02, 26 October 2015 (UTC)

Two issues:

  1. technical) Not sure what the identifiers should be. For Van Gogh, the URL is http://www.artprice.com/artist/11598/vincent-gogh-van It would seem that Van Gogh's identifier is 11598, contrary to other databases stripping the / does not appear to work. There may be another URL format that works but I could not find it. Unless someone finds it, I would suggest that we use longer identifiers: van Gogh's would be 11598/vincent-gogh-van
  2. it is a for profit database, and much of the content is under paywall.

metasubclass of

Description relation between two metaclasses: instances of this metaclass are likely to be subclasses of classes that are instances of the target metaclass
Data type Item
Domain metaclasses (classes that have instances which are themselves classes)
Allowed values metaclasses
Example
Source examination of Wikidata queries
Robot and gadget jobs Some opportunities for this, or at least to come up with cases for humans to consider -- see below.
However, the number of incidences of this property is likely to be quite limited.
Motivation

The motivation for this property grew out a discussion at Project Chat about the nature and characteristics of metaclasses.

Some further current examples, which may be surprising at first glance:

Arguably some of these relations might be better expressed as properties on the underlying subclasses. However, for the moment the relations between the underlying classes of the two sets of metaclasses are expressed by subclass of (P279) -- which means that the relation between the two metaclasses is indeed currently a metasubclass relationship.

An example of where a property has been introduced, and many of the relations have been changed to use it, can be seen in

Most television series classes use genre (P136) to express their relationship to instances of television genre (Q15961987). However, as a look at the "from related items" section of the Reasonator entry for soap opera (Q23739) View with Reasonator View with SQID reveals, there are still many television series classes using subclass of (P279) -- which should probably be discouraged, given the relationship can instead be expressed by a property.

Some further notes:

  • The property is intended to capture relationships other than those already captured by subclass. Therefore it should not be applied if metaclass A is genuinely a subclass of metaclass B -- ie if it should be understood that all instances of metaclass A are also instances of metaclass B.
  • Due to the transitive nature of subclass of (P279), all subclasses of a metasubclass A are also metasubclasses of the metaclass B. So the property should be applied to the highest item for which it is valid in the class tree on the domain side.
  • Similarly, a metasubclass A is also a metasubclasses of all superclasses of a metaclass B. So the property's value should be the lowest item in the target class tree for which it is valid. In this way the levels on the two sides of the property should match -- engine metaclasses with engine metaclasses, generic manufactured item metaclasses with generic manufactured item metaclasses.
  • The property is transitive: if aircraft model (Q15056995) is a metasubclass of aircraft family (Q15056993), and aircraft family (Q15056993) is a metasubclass of aircraft class (Q1875621), then aircraft model (Q15056995) is a metasubclass of aircraft class (Q1875621). But only the shortest steps in the hierarchy should be recorded.
  • It is possible that in future either Wikidata metaclass (Q19361238) or metaclass (Q19478619) may be used to manage a controlled vocabulary of metaclasses -- a set of metaclasses that had been 'signed off' as okayed by being made a subclass of one of these items, so that any attempt to use instance of (P31) from a class item to any item not in this 'approved' class would throw a constraint violation. If that happens, then any attempt the "metasubclass of" property on or to an item not in that class should also throw a constraint violation.

I've found the above candidates for the property using this query tinyurl.com/pazxyf4 to throw up potential matches. It could be refined, as at the moment it only has quite a low true positive rate. My main motivation for suggesting the property is therefore simply to record what of these quite curious relationships exist -- because even with the query, there's no obvious way to generate such a list algorithmically, it currently relies so much on manual validation. So given that it's hard to recreate such a list, it seems proportionate to introduce a property to be able to record it.

I should also emphasise that my intention would be for the property to be descriptive rather then prescriptive -- ie to try to identify and make accessible some relationships that are in the database currently, rather than to be proposing any relationships that should be in the database.

Of course, having identified such relationships, one can then look for gaps in them -- what classes that are instances of the metaclass on the domain side appear to be missing superclasses that are instances of the metaclass on the target side? (This is analogous to looking to see which items appear to be missing a particular property) Or, are there items that might be created to make structures more systematic -- for example, should a manufactured object family item be created, to be a superclass for aircraft family (Q15056993) and engine family (Q15057020), a "metasubclass of" target for model (Q17444171) ?

But my main motivation is simply to identify and have a way to be able to capture these patterns, which are currently implicit in the database, but not easily accessible. I think that's worth a property.

Symbol support vote.svg Support (after discussion) : captures something actually. BA candidate.svg Weak oppose as is, this may be a little clearer to contributors and a little more easy to enforce good practices, at the cost of complicating the model a little more, and to make a little more unnatural statements like "Porshe 911" instance of "car model". Would it imply a second version of instance of (P31) as well ? I'd like to hear a little more explanations from the proposer. author  TomT0m / talk page 10:12, 23 October 2015 (UTC) Needs a little more thinking after discussion.
@TomT0m: I hope you find the explanation above now a little more complete and detailed.  :-)
The thing I should stress is this is not an attempt to replace subclass of (P279), and I see no purpose that would need a meta version of instance of (P31). The aim is simply to capture some relationships that simply can't be expressed at the moment.
I don't think it really complicates the model much, as the number of instances of the proposed property would be vanishingly few. Remember, it is not intended to be applied where subclass of (P279) can be applied. So rather than being a heavy complication, I think a better way to view the property is as simply identifying a handful of curiosities -- which already exist in the model, they're just not easy to extract.
I think it will therefore hardly impinge on contributors or practices at all, as its domain of application will be so very very limited.
But I think it does have interest, and some potential for usefulness, so I do hope you might reconsider your initial oppose. Jheald (talk) 12:15, 23 October 2015 (UTC)
(ec) One way to look at the property is to see it in some ways analogous to properties for this type (P1963). For attributes of items that are expressed as properties, P1963 indicates what properties one might expect to find on a particular class of items. Analogously, for attributes of items that are expressed through subclass relationships, the proposed property indicates what sort of "subclass of" targets one might expect to find on a particular class of items. Jheald (talk) 12:35, 23 October 2015 (UTC)
@Jheald: So a good description would be "subclasses of instances of the subject metaclass's are instances of that metaclass" ? I think I'm beginning to understand : a typical car family subclass is a car models indeed. There may be other kinds of car famylies. But what's the value added to simply say that "car model" is a subclass of "car family" ? The "likely to be" in your description ? author  TomT0m / talk page 12:46, 23 October 2015 (UTC)
Because "subclass of" requires that every instance of a "car model" is an instance of a "car family". But that's not true: the two are considered different things. Jheald (talk) 12:59, 23 October 2015 (UTC)
@Jheald: Oh OK, I think I got it :) I was not careful enough. I'll have to think again. author  TomT0m / talk page 13:27, 23 October 2015 (UTC)
@Jheald: Sorry, but I fail to understand this proposal. Can you expand one or two of the example relation between two metaclasses: instances of this metaclass are likely to be subclasses of classes that are instances of the target metaclass wrt. say, the element example ? I can't understand the relationship beetween elements and rows in the table. author  TomT0m / talk page 12:32, 23 October 2015 (UTC)
Okay, so, if we look up chemical element (Q11344) View with Reasonator View with SQID in Reasonator, we find that there are 154 items that are instances of it, one of which is hydrogen (Q556), which is a subclass of (P279) of period 1 (Q191936) View with Reasonator View with SQID, which is a instance of (P31) of period (Q101843) View with Reasonator View with SQID.
But an instance of a Hydrogen is not an instance of a Period. subclass of (P279) is therefore not an appropriate way to model the connection between chemical element (Q11344) and period (Q101843). So I suggest this new property, and then the relationship could be captured.
Note that I'm not claiming that this is necessarily the right (or best) way to represent which period of the periodic table Hydrogen is found in -- I merely wish to be able to note that this appears to be how the relationship is seemingly being modelled, currently. Jheald (talk) 12:50, 23 October 2015 (UTC)
@Jheald: Mmm I wonder if correct in the first place ?
If we take the "atomic" definition of hydrogen (for simplicity) : «type of atom with number 1 atomic number», so the item may be hydrogen atom (Q6643508) View with Reasonator View with SQID, then this would make period 1 (Q191936) a subclass of atom, so a class of atom. period 1 (Q191936) is then "atoms of elements in the first row of the periodic table". This would make period (Q101843) View with Reasonator View with SQID a metaclass of atoms as well.
So if we say that:
  • «level 0» is the instance level,
  • «level 1» is the class of atoms level
  • «level 2» is the class of class of atoms level (so the first metaclss level
chemical element (Q11344) is on level 1 and period (Q101843) is on level 2, am I correct ? so you would suggest that the property, unlike «suclass of», links items on different levels ? Or is this a bad example polluted by the alternative elements definition ? author  TomT0m / talk page 13:21, 23 October 2015 (UTC)
It's a bit tricky. There are rather few examples, and they're not particularly easy to find.
To take the example you raise: one would be looking for instances of horse breed (Q3745054) View with Reasonator View with SQID to also be subclasses of instances of horse (Q726) View with Reasonator View with SQID. That doesn't work, because instances of horse (Q726) View with Reasonator View with SQID are individual horses, which have no subclasses. It's also the case that there aren't may instances of horse breed (Q3745054) View with Reasonator View with SQID that are subclasses of anything.
A typical chain currently seems to be Welsh Mountain Pony (Q18562203) part of (P361) Welsh pony (Q1096752), and both instance of (P31) horse breed (Q3745054).
Arguably Welsh Mountain Pony (Q18562203) ought to be subclass of (P279) Welsh pony (Q1096752); the "metasubclass" relationship would come in if Welsh Mountain Pony (Q18562203) were then also an instance of (P31) something like "horse sub-breed" that was qualitatively more specific than horse breed (Q3745054) View with Reasonator View with SQID -- so that an instance of a horse sub-breed was not considered an instance of a horse breed. Jheald (talk) 21:48, 27 October 2015 (UTC)
@Yair rand, Jheald: I got one more example : see
Atom classes.svg
. "Tritium atom" is a class of atoms, as "Hydrogen atom" is. We have SubType|Tritium atom|Hydrogen atom}} because any tritium atom is an hydrogen atom. But we don't have "isotope" (defined as a metaclass of atom) subclass of "element" (defined as a metaclass of atom as well) because "Tritium atom" does not belongs to the class of elements, only "Hydrogen atom" does. With those definitions, we would have "Isotope" metasubclass of "element". author  TomT0m / talk page 14:42, 2 November 2015 (UTC)
@Yair rand, Jheald, TomT0m: Please read that document before supporting or not this property.

This is typically the kind of decision which will have some impact later when we will build tools to extract information (not only data) from WD or when we will build tools to check data consistency. For me the use of metaclass or not should be a choice of the community with a clear description of the consequences, advantages and drawbacks of each option. If you have time this is another document comparing both structures. Snipre (talk) 15:53, 2 November 2015 (UTC)
You're a little late, this thing talk of metaclass in (object oriented) programming. A relevant notion would be Liskov substitution principle (Q957386) View with Reasonator View with SQID is that case. But we are not doing programming, and you can read metaclass (Q19478619) View with Reasonator View with SQID to see there is a lot more documentation for metaclasses on knowledge representation. But this precise property is far from being structuring for the use or not of metaclasses and will have a very low impact. If we really don't use metaclasses, which is really not true in current situation, then this property will just stay unused. No fear to have for ... what ? author  TomT0m / talk page 16:09, 2 November 2015 (UTC)
The essential question is do we want to allow a more automatic way to generate relation and in that case we will go towards some programming logic. I am not a specialist but I think this is a question which will have some consequences later or even nowas we are developping some query tools.
I don't agree with you about creating metaclass structure and decide later if we will use that system: creating that kind of structure will just allow parallel structures to be used and we will have to convert later all that workbecause we were not able to ask the good question at the good time. Snipre (talk) 18:52, 2 November 2015 (UTC)
@Snipre: You don't seem to understand. That property won't have any influence on us using Metaclasses or not as we simply don't need it to do so. The project about reasoning is WikiProject Reasoning, created by Markus who always have been supportive on my views about all these. He's an expert, so if this was anything of a problem to use metaclasses, we would know (I think I saw a draft from him and/or Denny about pushing metaclass modelling possibilities on OWL2). found it see Markus' edit on the history. author  TomT0m / talk page 19:12, 2 November 2015 (UTC)
So IF
  • Class A is an instance of metaclass B AND
  • Class A (and most other instances of metaclass B) is a subclass of Class C AND
  • Class C instance of metaclass D
  • THEN
  • metaclass B is a 'metasubclass' of metaclass D.
Is that it?
The bit I don't like is the "most" in the description above and the "likely to" in the property description. How to queries spot the exceptions?
Not convinced we need it. Joe Filceolaire (talk) 17:35, 8 November 2015 (UTC)
@Filceolaire: A good argument could be that it allows to represent some kind of "ordering hierarchy", for example in the case of "elements/isotope" metaclass couple, clearly isotope classes are "smaller" than their corresponding atom classes. An analog property for hierarchies of administrative division this is useful as well : regions/states whatever can be divided into smaller parts, which can be expressed by located in the administrative territorial entity (P131) more or less, but the order beetwen units type cannot (City<departement<region<country for example in france). A more convincing example could by taxons rank in biology : kingdom >...> genus> species, with taxons defined as classes of organisms. Then with "metasubclass of", we could express the rank hierachy : kingdom metasuclass of ... genus metasuclass of species. author  TomT0m / talk page 18:33, 8 November 2015 (UTC)

narrator

   Done. narrator (P2438) (Talk and documentation)
Description Narrator, character or person that tells the story
Represents narrator (Q755070)
Data type Item
Domain Fictions including movies, TV series, novels, etc.
Example In Search of Lost Time (Q464928)Narrator (Q3336121) or, if you want to spoil the would-be watchers, The Usual Suspects (Q132351)unreliable narrator (Q650118)
Motivation

The narrator is such an essential aspect of storytelling that we should not leave characters (P674) to deal with it. First because there are extradiegetic narrators (non-character narrators). Then also because the narrator may change in one story, so we need to be able to use qualifiers on the names we associate with the property. And the new property will let us call specific items that qualify the storyteller such as unreliable narrator (Q650118) or protagonist (Q215972), as suggested above. Thierry Caro (talk) 02:29, 9 August 2015 (UTC)

Discussion
Thierry Caro Can you fix the examples? the "->" represents the proposed property so the second item should be the value of the property - the item the property links to; in this case the character who acts as narrator. Joe Filceolaire (talk) 22:59, 11 August 2015 (UTC)
The examples are fine as they are but I admit they can be a bit misleading. So please let me explain them. The first example is to show that the value of the property can be a character and I chose In Search of Lost Time (Q464928) as an example because it is one of the most commonly used examples in narratology (Q382451) after Gérard Genette (Q266247) developed key concepts using that work as his main source material. Narrator (Q3336121) is both the narrator of the story and a character in the novel but we don't really know his name, except for one passage, and so critics usually call him Narrator (Q3336121). So In Search of Lost Time (Q464928)Narrator (Q3336121) is correct. As for the second example, it is here to show that the property could be used out of the literary field - for instance for movies - but also to show that we might use it with a value that would not be a character but instead one of those items about narrator-related concepts that we have here and that are used in narratology (Q382451), such as unreliable narrator (Q650118). At some point I think there will be more options because I think I will soon create entries for 'homodiegetic narrator', 'heterodiegetic narrator', 'intradiegetic narrator' and 'extradiegetic narrator', etc. All these concepts, again devised by Gérard Genette (Q266247), are the common way to describe a narrator in the discipline. And so The Usual Suspects (Q132351)unreliable narrator (Q650118) is also correct! Thierry Caro (talk) 17:16, 12 August 2015 (UTC)
I would expect something more of Joseph and the Amazing Technicolor Dreamcoat (Q1708306) => Maria Friedman (Q1165133). Mbch331 (talk) 17:34, 12 August 2015 (UTC)
If an actor is widely credited as a narrator I see no reason why they should not be accepted. Whatever, your question is interesting because there might be, for these kind of situations, a potential overlap with voice actor (P725). Maybe the latter one should change its English description? All other languages might use this only for people who dubbed a movie originally in another language while English users, with the current description set as 'voice actor', might also use it for actors who only use their voice but don't appear in a movie shot in their language. The property discussion page suggests that it was created to deal only with changes of language but the English description seems looser creating a potential collision with the property I suggest. The problem has been raised by a user back in 2013, with no answer. Thierry Caro (talk) 23:18, 12 August 2015 (UTC)
I oppose this if it is to be used in the way described by Thierry above. Instead I propose
  1. If the narrator is a character then the item for that character should be the value for this property.
  2. If the narrator is not a character in the book then don't use this property.
  3. If the character is in the book but not named then create an item named 'unnamed narrator' with description "of <name of the book>" and refer to 1. above
  4. If there is a narrator in a film or a play then name the actor and use the "Character role" property (or the "as" property) to say that this actor played the narrator. This might use a generic 'narrator' item.
  5. Add the qualifier <instance of:unreliable narrator> as a qualifier to this new property where needed. Joe Filceolaire (talk) 22:27, 23 August 2015 (UTC)

Proposed by Jobu0101 (talk) 08:23, 28 December 2015 (UTC)
Motivation

winner (P1346) is often used as qualifier for award received (P166). See for example this query: Query: claim[166:106301] and claim[31:(tree[11424][][279])]. We need a counterpart qualifier to winner (P1346) for nominated for (P1411). For the moment I'm using criterion used (P1013) (a proposal of User:Jura1), see this query Query: claim[1411:106301] and claim[31:(tree[11424][][279])]. But as User:Andreasmperu pointed out this property doesn't fit well. We need a new one. Once we have this new property I'd change the wrong use of criterion used (P1013).

But I wouldn't rename winner (P1346) (what User:Mbch331 proposed) because that property is not only used as quantifier. I think the correct way is User:ValterVB's solution to introduce a new qualifier only property to. --Jobu0101 (talk) 09:52, 28 December 2015 (UTC)

@Mbch331: @ValterVB: I realised that it is useful to restrict the new property not only to instance of (P31) of human (Q5). For example, in the early years the Academy Award for Best Picture was given to the production company and not to the producers. So here companies were nominated and we should use the new property also for them. Do you agree? Then I'd change the allowed values above. --Jobu0101 (talk) 12:05, 1 January 2016 (UTC)

To record grammatical gender of generic names. Seems like a very basic property (I cannot think why it is not here. Apparently grammatical gender is mostly used for inhabitants of countries: countries are inhabited by nouns with masculine grammatical gender and nouns with feminine grammatical gender). A lot of problems with adjectival epithets can be prevented by recording gender of generic names. It would seem handy to use this as a qualifier, but often it should be referenced.

In such cases I personnaly would render a label a/us without losing more time for nothing :) Anyway, I don't understand, the terminations are not hardcoded into the labels of the names ?

'grammatical gender' is a wiktionary property. we must not have a property with that name on wikidata or it will be terribly abused. I can only support this if the property name is changed to "gender of taxon name". Can someone reassure me that once this property is added then some basic logic will be able to generate all versions of a taxon name? Filceolaire (talk) 04:05, 21 July 2015 (UTC)
I don't understand the users who object because they would not use the new property themselves. But I have changed it to be restricted to generic names. The "some basic logic will be able to generate all versions of a taxon name?" suggests a misunderstanding: a taxon name has only one version (that is why a database is needed in the first place). To some degree the correct name can be generated by "some basic logic", but it will need more components (gender only applies to adjectives). - Brya (talk) 05:15, 21 July 2015 (UTC)
@Brya: I did not oppose, and you did not get the whole page : if gender of people is in the scope of Wikidata, gender of name is in the scope of Wiktionary, not Wikidata, so we're reluctant to vote for properties for names in general, and there is quite a few proposal about these. Taxonomy is a special case, but I did not understand your real use case I don't understand how it would be used for example in an infobox, so I'm still reluctant, although I did not oppose. author  TomT0m / talk page 07:46, 21 July 2015 (UTC)
There is no telling how popular this will be in an infobox, but there is no real reason not to include this. There are not all that many databes that include this information, but there are some.

Brya I don't say I object because I won't use it. I say that I object because others will use it for all kinds of purposes for which it is not appropriate. If "a taxon name has only one version" then this property is not needed and I Symbol oppose vote.svg Oppose it.
If it a taxon name has a second version when it is used as an adjective and this property will enable us to automatically generate that adjectival version AND the name is changed to make it clear what it is for then I would reluctantly support it. Which is it? Your reply above says both. Can we change the property to "taxon name used as an adjective" and make it a string property with the adjectival version of the name as the object? Joe Filceolaire (talk) 16:22, 22 July 2015 (UTC)
Well, the "taxon name used as an adjective" does not exist at all. The taxon names that have a gender are generic names. Say, the name Schinus, which is feminine, but much of the literature assumes it is masculine. The gender is relevant for names below the level of species, which consists of two or three parts. For example, Schinus terebinthifolia is the name of a species, but those who assume Schinus is masculine will write Schinus terebinthifolius. At the moment lots of names in the genus are subject to great confusion, with several having a separate "masculine" item and a "feminine" item. Recording the gender of the generic name will make it doable to bring this in order. - Brya (talk) 16:45, 22 July 2015 (UTC)
(out of topic) this is not really a surprise to me, fighting for correction into such an arbitrary concept is doomed to fail because people won't really care for good reasons.

Thanks Brya that is much clearer. If you just change the name of this proposed property to make it clear it only applies to the latin names of taxa (and not to common names or anything else) then I will support. Joe Filceolaire (talk) 15:54, 2 August 2015 (UTC)
Thank you for getting back to this, Joe Filceolaire: I had already adjusted the name of the property. I have now adjusted it again, hoping to have blocked any way of reading that might lead to confusion. - Brya (talk) 05:18, 3 August 2015 (UTC)
Sorry Brya but this is still misleading. Some applications drop all information in brackets so you shouldn't use these for essential info in labels. Can the label be "gender of the latin name of a genus" so it's clear it isn't to be used for common names.
There is also a problem with the description since 'generic' in English doesn't just mean 'name of a genus' it also means 'general'. Can we change the description to "used in taxonomy to generate names for species and sub-species".
This property should only be used on an item for a genus so the domain should be genus (Q34740). The items we have for 'generic names' are for human names and this property should not be used on those. Joe Filceolaire (talk) 13:18, 3 August 2015 (UTC)
A generic name can be derived from a greek noun too. Or another languages which has genders. May be these two ICZN articles help: 30. Gender of genus-group names and Agreement in gender --Succu (talk) 14:14, 3 August 2015 (UTC)
OK, Joe Filceolaire, tried again. As Succu said, the name of a genus need not be derived from Latin. But genus (Q34740) is something entirely else, conceptually speaking, from the scientific name of a genus. There seems to be no need to make a special item for a generic name? - Brya (talk) 18:31, 3 August 2015 (UTC)
Thanks Brya. 'Scientific name' is much better than 'Latin name' but I have edited it to remove the comma.
Your description is pretty much a repeat of the label. In my proposal for the description I was trying to include some of the info you gave above about how this is used and why it is important so I think my proposed label was better so I have replaced your description. Hope my understanding of what you said is correct.
While it is true that this is a property giving info about the name it is also true that it will only be used on wikidata items for genera. The domain field defines the class of wikidata items that can use this property. Technically I suppose this should be items with <'taxon rank':'genus'> so I have put that as the domain for this property.

Thank you Joe Filceolaire. Well yes, the description was very close to the label, as this concerns a basically very one-dimensional property, but I will see if I can rephrase it to make its import more clear.
        The use of the property is likely to be restricted to Wikidata, but there is no intrinsic reason why it could not be included in an infobox (see the example above of the database that has a field for it). In practice, this is useful and interesting information.
        I am fairly bewildered by the taxon rank (P105):genus (Q34740). Although there are many who will use a generic name to stand for a genus, the reality is more complicated than that. There are many more generic names than these are genera (ten times as many?), and of course there may be genera without a name. More than that, conceptually they are very different things. Generic names are subject to formal rules (and names do not have ranks), while genera are subject to scientific considerations. - Brya (talk) 18:41, 4 August 2015 (UTC)
@Brya: I don't understand. Did not you say that the gender was important because of the gender of the name of the corresponding genus ? Would the domain then be "names who are name of a genus taxon" then. It's not important that all genus won't have name, "domain" do not impose every instance of the class domain to have this property at all. And of course there probably is more name than there is generas, but if I understand correctly, one genus only have one name ? author  TomT0m / talk page 19:09, 4 August 2015 (UTC)
TomT0m: What's the difference between nomenclature and taxonomy? --Succu (talk) 19:17, 4 August 2015 (UTC)
@Brya: The description should add extra information to help users decide if the property is appropriate to use in a particular case. I think my description does that.
All properties on wikidata can be used all over the place. That's the point of Wikidata. All the more reason why we need to be completely clear about what each property is for and what it is not for.
What is a generic name? I am a well educated native English speaker with a large vocabulary and you have managed to confuse me. I suggest you avoid using the phrase "generic name" or define it (the definition can be as long as needed to make it clear what it is and what it is not).
<Domain taxon rank (P105):genus (Q34740)> means this property should only be used with items which have the statement "taxon rank (P105)->genus (Q34740)" that is it should only be used on an item for a genus. If this is not what you meant then you have failed to be clear about how this property will be used. Don't tell me the property is to specify the gender of scientific names - we don't have any items for scientific names so specifying that as the domain is the same as saying that this property should not be used - instead specify what items this property may be used on. This property could be restricted to only be used as a qualifier to taxon name (P225) but I would not recommend that.
Instead of writing me another paragraph of explanation I suggest you have a close look at the Label, Description and Domain statements above and rewrite these to be clearer, taking account of all of the comments by others above. The property will not be approved until these make clear what the property is used for and what it is not to be used for. Joe Filceolaire (talk) 22:46, 4 August 2015 (UTC)
@Joe Filceolaire: well, "generic name" is the existing term, used throughout the several Codes of nomenclature. Has been for a long time (a lot longer than computers have been in existence, anyway).
        And "<Domain taxon rank (P105):genus (Q34740)> means this property should only be used with items which have the statement "taxon rank (P105)->genus (Q34740)" does not apply. You vehemently opposed that, remember?
        Anyway, have tried to rephrase, as suggested. - Brya (talk) 05:39, 5 August 2015 (UTC)
Sorry Brya but I have to Symbol oppose vote.svg Oppose.
The label is misleading. The property is not for 'general nomenclature'. This property is only used to specify the gender of the scientific name of a genus. Nothing else (unless I have misunderstood you). The label should make this clear. The fact that the information contained in statements using this property can be used in nomenclature is info to put in the description - as you have done - not in the label.
The description uses the phrase 'generic name'. This phrase may be well understood in biology but the description is not for biologists; it's for non-biologists and for them this phrase is misleading. Delete the first 6 words and you would have a good description.
The domain has that phrase 'generic name' again. Just put a full stop after the word 'genus' and delete the rest. Then you would have a clear unambiguous definition of the wikidata items that can use this property. Joe Filceolaire (talk) 15:44, 5 August 2015 (UTC)
Joe Filceolaire, sorry but what is the common english usage of Generic name (Q5532676)? --Succu (talk) 15:57, 5 August 2015 (UTC)
Succu In biology it is "the scientific name of a genus" but item Generic name (Q5532676) links to a disambiguation page with lots more meanings. "Generic" has come to mean 'general, common, typical' in common English usage (based it's usage in 'generic medicine') so 'generic name' is likely to be misinterpreted as 'common name', 'given name', or 'family name'. Joe Filceolaire (talk) 16:03, 5 August 2015 (UTC)
@Joe Filceolaire : well, I am OK with "gender of a scientific name of a genus" (much better than "the"). And I can also do without the first six words of the description. Shorter anyway. I don't follow your argument that the existence of "generic medicine" or "generic statement" means that "generic name" will be misread, although it will no doubt be unfamiliar to many. It is possible to use "generic name" in English for something like "hoover has become a generic name for a vacuum cleaner, no matter the brand of the machine", but I don't see why that should involve a grammatical gender. - Brya (talk) 16:48, 5 August 2015 (UTC)

I never understood why Wiktionary has included some scientific names, apart from a desire to push some PoV or other.

The new Australian National Shipwrecks Database (ANSDB) was launched in December 2009. This database includes all known shipwrecks in Australian waters. New features of the ANSDB include many extra fields of information, the capacity to attach images to shipwrecks, the ability to link shipwrecks to relics recovered from shipwreck sites, site environment information for divers and site managers and a history field with the ability to attach documents that include names of passengers and crew. The information in the ANSDB has been collected by each of the State and Territory historic shipwreck agencies or supplied by collecting institutions holding historic shipwreck objects. This is the authoritative database of shipwreck information for Australian waters, compiled by and operated by the Australian Government (Department of the Environment).

Addition of this property would significantly enhance the information on the career and final resting places for over 10,000 vessels laying in Australian waters. Dhx1 (talk) 09:21, 22 November 2015 (UTC)

This would be useful as an authority control ID for British people. Oxford University Press's "Who's Who", unlike many of the subsequent publications which have stolen its name, is a widely-used reference work for British people since 1849 and this would help bring together a number of individuals who otherwise do not have reasonable authority control schemes for them, like sportspersons and politicians. James F. (talk) 00:12, 18 January 2015 (UTC)

This is an interesting one. OUP have an identifier system (which we've taken in as Oxford Biography Index Number (P1415)). However, this is currently only used for people with Oxford Dictionary of National Biography entries - if they also have a Who's Who entry the index page will point to it, but no identifiers are assigned for ~90% of the people in Who's Who. It's possible it may be extended in future, in which case we could certainly merge the two identifiers - it'll be easy to switch from one to the other.

Discussion

Motivation: Currently, it’s unclear whether the prefix should be included in the catalog code (P528) value or not. I propose that the best solution is to remove the redundant prefix from the catalog code (P528) values and extract it into a statement on the value of the catalog (P972) qualifier instead. This also allows language-specific prefixes to be displayed correctly (for instance, Köchel catalogue (Q162478) is abbreviated “K. ” in English but “KV ” in German).

Proposed by: DSGalaktos (talk)

  • Pictogram voting question.svg Question Are there any catalogues where the prefix is not separated from the code by a space? If we could make the space implicit, we’d probably avoid an otherwise common mistake where people wouldn’t be aware that they need to include a trailing space in the value in most cases. —DSGalaktos (talk) 17:49, 30 March 2015 (UTC)
  • I don't think we should store the space in the value of the catalog prefix property; this is a formatting decision. Whoever wants to display the (prefix, code) pair should decided whether they want to format it with a space or not. –Hardwigg (talk) 18:37, 13 April 2015 (UTC)
  • The most catalogs that I know have language independent prefix. For example HD prefix of Henry Draper Catalogue (Q111130) is written as "HD" in all languages. So string datatype is looked more preferred for this property. Also usually prefix is inseparable part of identifier. I never seen "HD 39801" identifier without HD prefix. So Symbol oppose vote.svg Oppose removing prefixes from catalog code (P528) or other properties. Issue with Köchel catalogue (Q162478) can be resolved using some other way, for example creating separate property for this catalog. — Ivan A. Krestinin (talk) 14:53, 12 April 2015 (UTC)
  • I’m not familiar with astronomical catalogues, but via German Wikipedia I found this lookup page for HD: VizieR – and there, you must enter the number without the HD prefix (with the prefix, you get this error: Unrecognisable token in: HD 39801). So if a template wanted to automatically link to VizieR results, it would presumably be easier if the value stored didn’t include the prefix.
    In addition to that, adding a separate property for any “problematic” catalog doesn’t scale at all. And regarding the language / data type, yes, most catalogues would only have a single value (presumably in English (en), unless there’s some special “global” language code that I’m unaware of), but that’s no reason to oversimplify the property to the point where it can no longer accurately represent all data. —DSGalaktos (talk) 16:01, 12 April 2015 (UTC)
  • Symbol support vote.svg Support I think separating out the prefix represents the data more accurately. The catalog code is just the number; the prefix represents the catalog. If you had the catalog in front of you, it would (most likely) not have the prefixes. On more pragmatic terms:
Pros:
  • removes duplication
  • allows for internationalization (K. vs. KV)
  • allows for simpler display customization: if you want to display the catalogue code in a special way, you don't have to to do any manual parsing to remove the prefix
  • Makes prefixed catalog code parsing possible: if you want to determine what catalog "HD 39081" belongs to, you could get a list of items with the catalog prefix property, and find the one which has "HD". This is currently not possible.
Cons:
  • more complicated to display data with prefix: in order to display "HD 39081", for example, you would have to get the catalog code (P528) value, then get its catalog (P972) qualifier value, find its prefix, pick the correct language, and then append the code to the prefix. However the fact that this is currently simple is a limitation in terms of internationalization and display customization. Furthermore, if you are only displaying certain catalog codes, this isn't an issue since you can store the prefixes locally.
  • possible duplicate of short name (P1813)? All of these could be achieved by using short name (P1813) with some qualifier specifying its purpose.
  • monolingual text would be annoying since most prefixes would be identical in many languages. However this is a problem that short name (P1813) faced when it was no label (P743) with plain string, and the end decision was to convert it to a monolingual. I think the extra complication is worth the internationalization.
Hardwigg (talk) 18:37, 13 April 2015 (UTC)
I wasn’t aware of short name (P1813), that does indeed sound like a very similar property. (Though, if the prefix should be identified by a qualifier on the short name (P1813) statement, that makes the prefix lookup for a catalog code (P528) statement even more complicated.) —DSGalaktos (talk) 19:10, 13 April 2015 (UTC)
  • Pictogram voting comment.svg Comment I’m having second thoughs on the data type, since I’ve recently discovered that in Hoboken-Verzeichnis (Q739093), the catalog of Haydn’s works, even the catalog code itself is written differently across languages. For instance, Symphony No. 94 (Q276768) is „Hob. I:94“ in German but “H. 1/94” in English: category and item are separated by a colon in German, but a slash in English. To fully represent this, catalog code (P528) would have to be changed to Monolingual Text, too. I don’t think this would be a reasonable thing to do, though: the vast majority of catalog codes are language independent, and it would be overkill to introduce the additional complexity of Monolingual Text just to deal wtih this one special case. And perhaps the same argument goes for catalog prefixes themselves, too; that really depends on how frequently the prefix is language-dependent. —DSGalaktos (talk) 21:30, 19 April 2015 (UTC)

Wikis need to display the prefix. Especially for astronomical objects, there seems to be half a dozen different catalogues – displaying the catalog codes without the prefix would be very confusing. —DSGalaktos (talk) 12:13, 30 April 2015 (UTC)
Beethoven for instance is not pathological: There exist only one catalogue (Kinski-Halm, maybe several editions or undisputed later amendments), there are two prefixes namely "op." and "WoO" (work without opus number, counted postumously). Both of these are "generic" prefixes and do not include a short name for the catalogue (since there is essentially only one it is implied as long as one agrees on the composer). And thirdly the display at http://viaf.org/viaf/184686463/ may give a gist how much variation different national (library) cultures can introduce into something as simple as "op. 27,2": Captialization of "op.", colons (se), commas, different abbreviations for "number" as the name for the subunit, even if one leaves the other components of the "usual reference forms" out of the equation and just focuses on the "catalog number". So if we talk about musical works, catalog code (P528) is highly language dependent and it does not make much sense to split some prefixes like "BWV" or "Hob." from the "number" itself: Those who don't now much about Bach would think "oh, it's opus 1248" and those who know so deeply are conditioned for "BWV 1248" that they probably would have a very hard time to grasp the meaning of an insulated "1248" in some data element. -- Gymel (talk) 12:54, 30 April 2015 (UTC)
I mostly agree with you, actually. My main issue with catalog code (P528) is that I strongly feel like the prefix should not be stored in that value. Most of what you say supports this, I think: If there are so many different ways to write a catalog code (K., KV, op., Op., etc.), then we need to strip away as much as possible of this representation data, because there’s no “one true representation”, and because we can’t possibly hope to be consistent in which representation we choose. But wikis still need to display the correct, pretty, full catalog code: Somehow, needs to be turned into “K. 620” (English), or “KV 620” (German), or the proper representation for other languages. Do you have a better solution than the property I suggest? —DSGalaktos (talk) 13:41, 30 April 2015 (UTC)
I rather see similarities to "numbers with units" e.g. 1 m³ which even require a datatype of their own. Strings like "op. 27,2" and "BWV 1248" as notations I consider equally atomic (within their contexts and all language specific variations notwithstanding) and your and my examples above illustrate that language specifics are not restricted to some prefix but rather are found throughout the whole "number". So perhaps the problem lies only in an improper naming of catalog code (P528) for some languages, where the label uses "number" instead of "code" or "mark" and therefore implies something that could or should be simple and unstructured? I'm not sure what problem the proposal actually tries to solve, but I would say there is no way in the general case to use properties like catalog code (P528) for sorting nor searching. Some problems like unambigously identifying the work in question might be solved by providing a semantic web URI pointing to a linked data version of exactly that catalog entry evoced by the string value of catalog code (P528), but I'm not aware of any catalog in that form (but there are probably examples in STM areas). -- Gymel (talk) 14:37, 30 April 2015 (UTC)

Moreover, it is already scheduled on the french Wikipedia (other versions will follow) to extract this property the first three riders, see Module:Infobox/Étape (and as time and average speed when possible).

J'ai fait quelques tests pour les listages d'équipes, et il serait bien plus rapide pour moi de taper un classement par équipes que d'ajouter un rang à la liste des équipes participantes, tout simplement parce qu'il faut aller chercher les équipes unes à unes, tandis que pour définir un classement il faut simplement mettre les deux documents côté à côte. Lister les équipes participantes ne me prend plus que 3 minutes. Tant que je n'aurais pas la propriété pour le temps et l'écart ce ne sera pas intéressant.

Ok, I'm new to wikidata so I hope I filled out the above correctly, but in a nutshell I'm trying to build a new type of infoboxes for companies that would include essential information such as number of employees, operating income (there already is a pending / accepted request for that) and debt rating, amongst others. In the present case, credit rating is an essential element of economic publication these days, and with all the talk about indebted countries there really is a demand for such information. 95% of the credit rating market is dominated by only three agencies (Fitch, Moody's, Standard & Poor), which makes their evaluation a de facto standard (and it is already, to some extent, a standard by law)

Discussion
Welcome to Wikidata. :) I know absolutely nothing about economics, so I can't really say whether or not I think we should add this, but I do have a few more general comments:
Please don't remove the TranslateThis sections in property proposals - that's there so that people can add the name/description in other languages.
For fixed lists of values we normally use items for each value, rather than strings, see the allowed values on the talk pages of PEGI rating (P908) or MPAA film rating (P1657) for example.
This seems to be three separate systems for credit ratings, if so, I think three separate properties would be better, one for each system, in the same way that we have separate properties for separate film/game rating systems. - Nikki (talk) 18:52, 9 July 2015 (UTC)
