This page is for the proposal of new properties.

Before proposing a property

  1. Check if the property already exists by looking at Wikidata:List of properties (research on manual list) and Special:ListProperties.
  2. Check if the property was previously proposed or is on the pending list.
  3. Check if you can give a similar label and definition as an existing Wikipedia infobox parameter, or if it can be matched to an infobox, to or from which data can be transferred automatically.
  4. Select the right datatype for the property.
  5. Start writing the documentation based on the preload form below and add it in the appropriate section.

Creating the property

  1. Once consensus is reached, change status=ready on the template, to attract the attention of a property creator.
  2. Creation can be done 1 week after the proposal, by a property creator or an administrator.
  3. See steps when creating properties.

Motivation

(See also the later comments in this discussion at WikiProject Books, in particular the comment by User:Valentina.Anitnelav, 10:56, 4 May 2018)

The Biodiversity Heritage Library (Q172266) (see Wikidata:WikiProject BHL) includes a dataset with 225,000 subject keywords for the books etc we have items for, that I would like to add to the relevant items here.

However, it seems to me that main subject (P921) is not the right property for the job. Consider a book like A systematic arrangement of British plants :with an easy introduction to the study of botany (Q51423679). Its "main subject" might be classified in library catalogues as "Botany -- Great Britain" and "Botany -- Ireland" (in fact, that is exactly what is stated for its subject at OCLC Worldcat).

But the keywords file gives keywords "Great Britain", "Ireland", and "Plants". However "Great Britain" is not the main subject of the book. Anyone looking for a book on "Great Britain" generally would be disappointed if a search returned this book, because it is not a book on Great Britain generally. Therefore IMO it would be wrong to record main subject (P921) = Great Britain (Q23666).

Instead, "Great Britain" is an aspect or a facet of the main subject of the book.

It's very useful to be able to record this, because one can then ask for the set of books which have "Great Britain" as a facet of their subject, and then what other facet-topics it is found in combination with, and thus progressively derive a narrower and narrower, more and more refined final solution set - a process known as faceted search (Q1519370).

This is therefore something valuable to be able to record. But these are not "main subject"s of the books, so P921 is not appropriate, and we would therefore benefit from having a new property for statements of this kind instead. Jheald (talk) 23:10, 10 June 2018 (UTC)

Discussion

Pictogram voting comment.svg Comment A subject keyword is a main subject (P921). So what you propose is a "Schlagwortkette" (subject string / subject chain)? For creating "Keyword: Great Britain (Q23666) – subfield: plant (Q756)" we would need to add the qualifier series ordinal (P1545). Otherwise subject keyword + subject keyword = main subject (P921) + main subject (P921). --Kolja21 (talk) 01:49, 11 June 2018 (UTC)

@Kolja21: No, I don't think so. As I understand it, a P921 value should correspond to a complete "Schlagwortkette". This is why in English property P921 is called "main subject". An appropriate P921 for the book above would be a non-category item corresponding to Category:Flora of the United Kingdom (Q6324043).
That is why I am proposing this new property, for an individual Schlagwort from that Schlagwortkette.
Your suggestion of how series ordinal (P1545) might be used as a qualifier is interesting, although that information will not necessarily always be available (eg when just a list of keywords is supplied), nor necessarily unique (eg if both "Great Britain -- Botany" and "Botany -- Great Britain" were given as Schlagwortketten). Jheald (talk) 07:09, 11 June 2018 (UTC)

Symbol support vote.svg Support To summarize the discussion at Wikidata_talk:WikiProject_Books#subject_areas_and_genres: There is a need to express that a book is written in (or of interest for) a certain academic discipline/subject area. Sometimes genre (P136) is used, but it is at least debatable if mathematics is a genre. To use main subject (P921) would lead to problems, too, as the academic discipline is rarely the main subject of a book written in it, leading to many false positives. This property could be used to indicate this information without "dumping" it into main subject (P921) (and making it more or less useless for some topics). - Valentina.Anitnelav (talk) 15:43, 11 June 2018 (UTC)

  • Symbol support vote.svg Support To avoid confusion in current use of main subject (P921). We would probably want to split off some of the aliases there (for example "keyword") that are not entire subjects in themselves. ArthurPSmith (talk) 18:38, 11 June 2018 (UTC)
  • Symbol support vote.svg Support Very helpful for many of the books I add. - PKM (talk) 22:12, 11 June 2018 (UTC)
  • Pictogram voting question.svg Question As usual with those kind of « fit all property », « a facet » is something undefined. What does this mean? The proposal does not say this. It just explain, totologically, « "Great Britain" is an aspect or a facet of the main subject of the book. » (it’s a facet because it’s a facet) . Actually, the book seem to be about the botany of some places in the world. « plant of great britain » seem to me a legitimate item, and instead we can use location and usual more precisely defined properties to describe this item. Why not doing this? This is the Wikidata way. But I guess this kind of argument is bound to fail when I’ll get tired of saying this again and again… Put another way, if we want to explain what a facet it, we have to put a list of what a facet could be? We know currently « a facet can be the location of the stuff the book describes ». Or pretty much anything else? This is just a proxy for « the book has a vague relation with this topic ». Same problem with categorisation. author  TomT0m / talk page 15:23, 12 June 2018 (UTC)
@TomT0m: "Location" is not what we are looking for here. We are not trying to say where the book is located, we are trying to indicate what it is about. The whole point of keywords is that they can be almost anything, and the mechanism of combined keyword search still works the same. If one wants to look up what kind of thing a keyword is, one can look up its P31 -- one doesn't need (or want) a separate property to indicate keywords relating specifically to location.
I am all in favour of adding main subject (P921) to books as well, if the data is there, and items exist for the relevant values. But I don't have a dataset of 225,000 "main subjects", what I have is a dataset of 225,000 keywords -- which I think it would be useful to be able to add. Jheald (talk) 18:24, 12 June 2018 (UTC)
@Jheald: I did not mean put « location » on the book item, I meant having an item « flora of GB » which would held the value. « one doesn't need (or want) a separate property to indicate keywords relating » this is exactly what « facet » is, it seems, « related to ». I guess it’s something we always avoided in Wikidata, putting « related to » which basically could be a superproperty of any property, conceptually, as the all point of property is to establish a relation. I’d actually be in favor of having a « keyword » property (specific to your dataset) that links our items to the used lexeme, this would be interesting, but I’ll always favor more semantic relationships, especially if the (raw) datas are available elsewhere, over importing raw but less wikidataish datas such as « keywords ». There is probably a service somewhere on the Internet where these documents can be queried by keyword, isn’t it?
Having a location as a keyword does not explain how the topic of the book is related to the location itself. Can be location of the intrigue, or a book entirely dedicated to the location itself, or a book about something that is located in this location, … author  TomT0m / talk page 18:46, 12 June 2018 (UTC)
If the book is "entirely dedicated" to the location, that should be indicated with main subject (P921). What keywords allow is a more exploratory search style: having searched eg for a keyword that is a location, one can then see what different other sorts of keywords are associated with that set of items -- eg "crime", "plants", "history", etc -- and make a choice at that point as to how to further narrow down the selection, rather than having to know and precisely specify the full subject at the start. It's a powerful (and quite simple) technique, which is precisely why so many information retrieval systems find keyword indexing a useful thing to include. Indeed, it's exactly what the Structured Data project is hoping to create for Commons -- for images we already have the depicts (P180) property which works like this. This equivalent for other kinds of creative works would be useful. Jheald (talk) 19:08, 12 June 2018 (UTC)
In a keyword system, the main topic should hopefully be reflected in the keyword :) so that does not exactly seem like a good argument as you plan to mass import the keywords without verifying if the keyword is actually a main topic. For images, the semantic is pretty clear, there is a representation of the item’s topic in the picture. But if your proposal is structured datas, then wikipedia categories are as well :) But it is not: it’s not, by current definition, it’s not a set of relationship beetween the topic of the book and the topic of the keywords according to a data model, it’s just a bag of keywords with no hint on the relations. author  TomT0m / talk page 19:22, 12 June 2018 (UTC)
A bag of keywords can actually be a useful model. In fact, as many information retrieval and library systems have found, it can actually be the most useful retrieval model -- more useful than old-school subject-string models. I'm not against adding detailed "main subjects", but stop getting in the way of this, which is (i) available, (ii) useful, (iii) very widespread across the board as keywords given for articles, papers, journals, books, etc, etc. It's data we ought to be able to reflect. Jheald (talk) 20:08, 12 June 2018 (UTC)
@Jheald: I don’t really like that tone. Please don’t make this personal or give orders. « It's data we ought to be able to reflect » As it’s an argument I already think I gave my opinion on, this information is already queryable on the web, I don’t really see how it’s really important to have it in Wikidata in the same exact form. Also you try to fit different indexation systems into one database, Wikidata, whereas those different database may have different policies on keywords and index the same documents. How to deal with this with only one property? If keywords are structured by an ontology as you seem to imply without really explaining clearly how, are they useful without importing that ontology as well? Also I don’t really understand the relation with faceted search, which rely on faceceted classification. We can already do faceted classification with metaclassification for example using instance of and subclass of, but faceted search means adapting the presentation of the search interface or the result to the topic of interest, for example what resonator does by displaying differently different kind of items. Or displaying a human which is both a scientist and an artist as a scientist is displayed or as an artist is displayed. But to do this, you need to have informations about the properties, not keywords! On does that mean that having a « scientist » facet for a book means you can search using a search interface which is specialized to find scientists?? for example a field the search for the university in which he graduated? Sorry but I’m deeply confused by your approach of the topic and your arguments. author  TomT0m / talk page 21:18, 12 June 2018 (UTC)

  • The topic of a book could be qualified. The subject could be plants (or ferns, trees ..) location Great Britain.. When this is done right, these would be the ingredients for a query. A similar pattern is used for "Catalog contains" where "human" combined with "position held" "position" is used extensively. So no, this would not work for me. Thanks, GerardM (talk) 18:22, 12 June 2018 (UTC)
    • @GerardM: I have 60,000 titles. I don't have the means to work out how all those keywords relate to each other, all I have is the dataset of the keywords without relationships given between them. The whole world uses keyword search and finds it useful. (cf category combines topics (P971)). The data is there for us, all nicely made ready on a plate. All we need to add, to be able to upload it and use it, is a property to link a title to a keyword. Jheald (talk) 18:33, 12 June 2018 (UTC)
      • @Jheald: When I get the time, I need a few days to achieve this, I will be able to have all the books and authors of the BHL organised so that it becomes easy to link them through identifiers and insert both books and authors to Wikidata. When there is a book with keywords: "Great Britain" and "Ferns" then with some simple logic it is easy to understand those relations. So no, we do not need this. Thanks, GerardM (talk) 19:22, 12 June 2018 (UTC)
        • @GerardM: No, Gerard, please don't upload any more BHL titles for the time being. It is enough trying to digest the first 60,000, de-duplicate them, identify authors properly, work out which ones should be editions, periodicals, etc., put them into proper work -- edition relationships, etc, etc. Until we can get this first batch properly cleaned up, more items would not be helpful right now.
          And please also don't sabotage the possibility of straightforward keyword searching. Jheald (talk) 19:59, 12 June 2018 (UTC)
          • @Jheald: In a previous life I earned a considerable amount of money as a database programmer. When I have the database downloaded and properly organised on my computer, I will perform disambiguation using database tools. Many of the books of the BHL have been identified with LoC identifiers. The BHL content resides typically on the Internet Archive. I have my contacts there. I will prepare my database in a way that allows me to ingest new content from the BHL and know they are new. When I can get an export from Wikidata, I will be able to associate books with authors per the existing links. Now you can tell me nothing what I do at home. What I will do when I am done is explain the process I have performed.
As to this proposal apparently people are only allowed to agree with you. I do not. Thanks, GerardM (talk) 20:46, 12 June 2018 (UTC)
@GerardM: Beware. I was looking at the LoC identifiers this afternoon. It's not that good a dataset. Of the 60,000 BHL 'title' items we currently have, about 28,000 have LoC identifiers, but many of them are wrong. So it's important to check them against the LoC itself, to make sure they are actually correct.
Secondly beware that not all books here have proper instance of (P31)s as books or as editions, nor do they necessarily have author (P50)s rather than author name string (P2093)s.
Thirdly, please make sure that any matching is rather better than your often-proclaimed 4% error rate. In my view, to be acceptable, an error rate ought to be nearer 0.01% -- ie no more than 10 mismatches or duplications in 100,000 entries. That's the standard a data upload should be trying to achieve.
Finally, I don't mind people disagreeing, or having vigorous discussions to find the best data modelling. What I do object to is people blocking whole approaches entirely to the extent of preventing whole data retrieval structures and delaying particular data uploads indefinitely. It may be that you want to be able to represent things differently, I'm not stopping you, but get out of the way of people who do want to be able to do things this way, and accurately represent data (in this case keyword information) in the way it is/was presented in the sources it was derived from. Jheald (talk) 21:16, 12 June 2018 (UTC)
@Jheald: You are telling me what to do and what not to do. Let me do my own research and let me consider what I think is reasonable. I do not subscribe to your notions. I do not agree with your approach because your argument is basically "it is the same shit, so who cares it is shit". Your notions about error rates are unrealistic it is not achieved in our data at all. Thanks, GerardM (talk) 01:08, 13 June 2018 (UTC)

Pictogram voting comment.svg Comment Hi, I'm a librarian, I leave out the last part of the discussion: I think that generic "keyword" could be good. However, it is very important to always add references to the thesaurus or ontology of origin of the terms. Nonoranonqui (talk) 08:12, 13 June 2018 (UTC)

Symbol oppose vote.svg Oppose Just creating complexity for nothing. Why is it a problem to say that the subject of the book is about botanic, Great Britain and Ireland ? The generation of a huge list of possible items if looking for all books having Great Britain as subject ? But this is the idea. Botanic of great Britain is part of Great Britain, so I don't understand why we have to consider it in a different way. The main problem with the proposal is the lack of rule specifying what should be in the defined by the subject property and what should be defined by the subject facet property. This is completely arbitrary so if people will do as he wants and at the end it would be impossible to propose a correct way to build query using two different sets of data. Snipre (talk) 23:00, 13 June 2018 (UTC)


Symbol support vote.svg Support, as per Valentina. But: is there a way to use a more general 'keyword' property? Is tihs really specific to 'subjects' or is it about facets of any sort of work more generally? Sj (talk) 19:18, 8 July 2018 (UTC)

Discussion linked to from wikicite-discuss mailing list. [1] Jheald (talk) 07:09, 27 July 2018 (UTC)

Pictogram voting comment.svg Comment I'm generally in favor with this proposal and in agreement with the motivations, but I wonder how external data providers will feel about a controlled vocabulary being casually mapped to Wikidata items by contributors. Case in point: a bibliographic catalog maintains a vocabulary of keywords that are not yet mapped to Wikidata. Bibliographic data from this catalog is ingested into Wikidata and the community start manually adding subject facet statements matching keywords in the original record (or creating new topical items when needed). At some point, the organization behind the catalog introduces a formal mapping of their keywords to Wikidata items. How is this situation going to be handled in the case of conflicts and is this going to be a common scenario? Basically a community member and the original authority behind the data may disagree on the proper target of this property when interpreting the meaning of a keyword. I think the proposal should also clarify if the values should be restricted to those specified by the authority for this record (in which case provenance information should be made mandatory), or can be freely added by Wikidata contributors.--DarTar (talk) 23:09, 26 July 2018 (UTC)

@DarTar: You may be more familiar than I am with organisations taking on to map their own controlled vocabularies to Wikidata themselves. I am sure that does happen, and in future I hope it will happen more. But in most cases (as has been the case with eg the matching of external thesauruses using Mix'n'match), I would think the values will have to be matched and added by the community (or more likely by one or two motivated individuals, perhaps using OpenRefine, and then batch-adding the relevant 'subject facet' statements), because that's how I think this will get done.
But you raise an important point, about transparency and traceability and contestability and improveability of the matching of the controlled vocabulary -- because (unlike matching a thesaurus to an external ID), the matching will not have a visible localised nexus in a single particular statement on a single particular item, but will be embodied implicitly in statements across the dataset. So how to retrieve and review and if necessary correct or improve such matches, after the event? Well, I'm a big fan of broad use of the stated as (P1932) qualifier. Using this one can attach the original string to a statement, as well as the Wikidata Q-number. If this is systematically used, then that gives us the traceability, and it becomes straightforward to produce a query or a Listeria page, matching the original controlled-vocabulary string to the Q-number (or Q-numbers plural) that have been used to represent it. If the data-source has a Wikidata project page (eg Wikidata:WikiProject BHL for the Biodiversity Heritage Library), the matching of various strings could then be discussed on the talk page, or perhaps just a note left to say that some of the matching had been updated, and was everybody okay with that. If there was a Listeria page, then that would give an audit-trail history of precisely what changes had been made over time.
P1932 can thus be used for subject keywords that are given as a string. If the subject keyword is given as a coded thesaurus identifier, then it may make more sense to give that as the qualifier instead (or as well). These qualifiers would be queryable in exactly the same way.
If keyword statements are coming from an external source, then yes the source should definitely be referenced. That should indeed be a mandatory thing. But there may be cases, for example, where there isn't any external source that has subject-indexed a particular set of works. Then editors should be free to add subject keywords from their own assessment; and it's probably also important to be able to add additional subject keywords, even when a set is available from an external source. How should this be indicated? One alternative would be the keywords simply not having a reference statement in such cases. A different approach, that might be preferable, could be to require a reference statement (subject to a constraint check), but allow people to give stated in (P248) = <no value>, or inferred from (P3452) = title (Q783521), or inferred from (P3452) = "Schlagwortkette". That would then clearly distinguish keywords that were editor-supplied, as against cases where the reference had simply been forgotten. Jheald (talk) 08:28, 27 July 2018 (UTC)

I agree that we need something besides main subject (P921), but that something and its use should be better defined (and delineated from P921) than what we currently have in this property proposal. Something like "keyword" also seems to be a more promising way of framing this than the very nebulous "facet". --Daniel Mietchen (talk) 11:32, 27 July 2018 (UTC)

Pictogram voting comment.svg Comment Agree with Daniel that this proposal needs a little bit more thought before we proceed. It's especially important that we first think of some way to source the values so that people won't just start adding random values to items. Husky (talk) 12:09, 27 July 2018 (UTC)

  • @Jheald: it seems people would be happier with "keyword" (or "subject keyword"?) as the English label of this property, is this ok with you? Regarding the discussion on sourcing above - how is this different from any other data in wikidata? ArthurPSmith (talk) 17:07, 27 July 2018 (UTC)
    • @ArthurPSmith: Yes, absolutely, whatever people want to call it. Keyword is obviously the much more familiar term. The one reason I didn't go for it is a slight mantra that Wikidata items represent things, not words or terms; also "keyword" might suggest something language-dependent, whereas Wikidata's aspiration is to represent things in a way that is as language-independent as possible. But I am not going to get on any horse about what the property is called -- what it operationally does is what matters. As for sourcing: agree completely, how or why is this different to anything else that goes or doesn't go on Wikidata. Jheald (talk) 19:31, 27 July 2018 (UTC)
      • Yea, it seems like a fine + useful use of this for anyone to add a keyword -- as long as we can distinguish a definitive map stated by an existing ontology, from the analysis of an individual editor. Community norms would govern what constraints if any there are on sourcing, a norm that might change by field or topic. Sj (talk) 21:29, 27 July 2018 (UTC)
    • +1 for using "keyword". As to whether that implies a word vs. a concept, I note that FRBR-aligned Bibliographic Ontology (Q44955004) has "subject term" <subclass of> "concept" defined as "A concept that defines a term within the controlled vocabulary of a particular classification system ... used as an annotation to describe the subject, meaning or content of an entity." I'd say the property fabio:hasSubjectTerm is an exact match for what is proposed here (and perhaps "subject term" would be a good alias for "keyword" on that basis). Details of "subject term" in FaBiO here, p. 7. Perhaps we should change the description of this property to something like "term or concept used to contextualize this item in an external vocabulary, catalog, or datasource". I'd like to include catalog since publisher's catalogs frequently have a list of keywords for books they publish. - PKM (talk) 21:21, 28 July 2018 (UTC)
  • @Jheald, PKM: I updated the label and description based on PKM's comment above. The "OR" is to indicate one of these should be label, the other an alias, as our property templates don't have a spot for aliases. Any further thoughts? @Valentina.Anitnelav, TomT0m, GerardM, Nonoranonqui, Snipre: @Sj, DarTar, Daniel Mietchen, Husky: please note "facet" is no longer part of label or description here. ArthurPSmith (talk) 13:45, 30 July 2018 (UTC)
  • Symbol support vote.svg Support as amended, and happy with either “subject term” or “keyword” as the label. Very useful in my work for books used as references where the publisher may choose keywords like “costume” and “textiles” for cataloging options but where WD can support a more specific “main subject” like “medieval costume” or “costume of Spain”. - PKM (talk) 17:39, 30 July 2018 (UTC)
So the argument is to allow importing publisher keywords of low quality such as “costume” and “textiles” and keeping such broad keywords instead of grudually improving them with more specific terms such as “medieval costume” or “costume of Spain”?! -- JakobVoss (talk) 05:50, 8 August 2018 (UTC)
  • Symbol support vote.svg Support in the amended form. Slight preference for 'subject term' because 'keyword' seems to suggest you can use arbitrary words, while 'term' feels a little bit more strict and defined. Husky (talk) 20:51, 30 July 2018 (UTC)
  • Pictogram voting comment.svg Comment Hi, sorry for joining in late. I recognize the problem, that the wording "main subject" does not always capture is, besides just suggesting there should be a "minor subject" too. To me, this proposal sounds a bit like the "minor subject", and I agree that could be a nice complementary property. But I would like to make people aware that we already have another granular mechanism to say what a paper is about: using that paper as "reference" for Statements. For example, if we have some paper as reference on the statement that the chemical compound acetic acid (Q47512) pKa (P1117) 4.74 (the reference paper actually being Small Scale Determination of the pKa Values for Organic Acids (Q23571464)), this also provides topics the paper is about, one perhaps a "main subject" (the compound) and the other (the concept of acid dissociation constant (Q325519) via the property) perhaps being a "subject facet"... --Egon Willighagen (talk) 05:38, 7 August 2018 (UTC)
  • Pictogram voting comment.svg Comment What's to stop someone adding all the keywords from the index of a book, to the item about that book? We all know that, if someone can do so, they will. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:39, 7 August 2018 (UTC)
  • Symbol oppose vote.svg Oppose A new property this broad should be justified by more and independent use cases, in addition to the dump of keywords to be imported into Wikidata. The proposal only gives a single example and wrongly assumes a narrow use of main subject (P921). The existing property is also used as proposed with "main subject" as "one of the most relevant topical aspects or facets" instead of "the primary and only subject". -- JakobVoss (talk) 20:44, 7 August 2018 (UTC)
  • Symbol oppose vote.svg Oppose. This would be insufficiently structured. "Botany in Great Britain" could be a valid main subject, which could then be properly informative and filled with useful statements. A set of keywords tells us nothing. --Yair rand (talk) 06:24, 20 August 2018 (UTC)
@Yair rand: A set of keywords is very helpful for retrieval -- so "it tells us nothing" is simply not true. The question here is whether we use main subject (P921) = "botany", "Great Britain" for such keywords (per User:JakobVoss above), or whether we use a different property and reserve P921 for subject-strings that are more encompassing.

Motivation[edit]

Airon90 Tris T7 TT me Tris T7 (talk) ...

Pictogram voting comment.svg Notified participants of WikiProject Pokémon WD:PKMN seems dead so I make this proposal here, without a earlier discussion. Some Pokémon species change, they evolve and since 2nd generation they can also recess by making an egg and sometimes the original Pokémon must own an item. There are also many ways to evolve a Pokémon: some by level, some by giving a stone, some in a particular (and unmappable singularly) way (e.g. by level and turning 3DS upside down, under the rain or when another Pokémon reach a level, there is room in the team and you have a Pokéball in the bag). This kind of information is important and must be mapped in Wikidata but as long as it need some subproperties to define the way to evolve, I think this needs a standalone property. The name of the property is temporary so if needed, change it. I'm going to show you how to map items: the property will be useful for both evolution and "deevolution" (I don't think there is a specific term for that kind of operation). The property must have one of these as statement, for each way of (de)evolving:

  • leveling up
  • leveling up with high level of friendship
  • leveling up while holding an item
  • leveling up while knowing a certain move
  • leveling up in a certain location
  • leveling up during a certain time of day
  • leveling up while holding an item during a certain time of day
  • leveling up while is a certain gender
  • leveling up in a certain game
  • leveling up with a certain Pokémon or Pokémon of a certain type in the party
  • leveling up while the Nintendo 3DS is upside-down
  • leveling up a Pokémon during certain types of weather.
  • trading the Pokémon
  • trading the Pokémon while holding an item
  • trading the Pokémon for specific Pokémon
  • using an evolutionary stone on it
  • by a particular method
  • breeding
  • breeding while holding an item

Items must be created yet. Then:

  • In case of leveling up, it needs numeric value (P1181) to define which is the lower level in order to trigger evolution
  • In case of item to be held, I honestly don't know if applies to part (P518) or item operated (P121) should work
  • In case of move/type of move to be known, the time of day, the gender, the game, the Pokémon/Pokémon type, the weather, the specific Pokémon to be traded and the evolutionary stone to be used, the property applies to part (P518) should work well.

Every statement should have also direction (P560) in order to define which Pokémon you get after the (de)evolution.

I think I wrote everything. During next week I will create items about evolution, if a sort of consensus is found --★ → Airon 90 09:24, 3 October 2018 (UTC)

I already considered this option but don't think it is useful, because it would need a qualifier for the qualifier and as of now, Wikidata doesn't have such option: indeed, if I use followed by (P156) then I need a qualifier to define how the item (de)evolves into that specified Pokémon and then I need a qualifier for the qualifier to clarify level/item/Pokémon/...

EDIT: IMHO, I also think that it doesn't have any sense to partially map the way of evolution. It is useless to just know that certain Pokémon evolve leveling it up or trading it with another Pokémon withour specifying the level which it evolve since or the Pokémon needed to be traded to trigger evolution. I think that either we allow mapping all data properly or it is useless partial work and it would be then better not to map at all these data :) --★ → Airon 90 06:53, 7 October 2018 (UTC)

significant event (P793) with qualifiers is currently used for this.

    • @ArthurPSmith, Yair rand: The problem with significant event (P793) is that it can have as value the specific event or a generall occurence. Let's look at the new Pixel 3 (Q57179556), let's use significant event (P793), do we put as a value Google I/O (Q668984), Google I/O 2018 (doens't exist yet) or just presentation (Q604733) or announcement (Q567303) (announcement should have have series ordinal (P1545)=1 so it's clear that it's the first announcement and not just any), or even both. How do you query it??? Having a simple property "date of first public presentation/annoucement" will make it much easier Germartin1 (talk) 09:01, 11 October 2018 (UTC)
      • I'm sure this has come up before in other contexts. Maybe we should split significant event (P793) into two, one to point to specific event items, and one to point to generic types of event? In any case I don't think we need special properties for each generic event type. The ones mentioned above were created early on and probably wouldn't be approved now. ArthurPSmith (talk) 18:23, 11 October 2018 (UTC)
      • (edit conflict) @Germartin1: Hm, this is a good point, but it's applicable to essentially all the varied uses of P793. The presence of using specific instances of more general classes in P793 breaks use of qualifiers like P1545, and makes querying more difficult in general. Perhaps we should just eliminate use of such instances, and link the more specific item by a qualifier? I don't think working around it for one specific type by creating a new property is a good idea, but this is something that needs to be fixed somehow. --Yair rand (talk) 20:27, 11 October 2018 (UTC)

To find the same connections you can make a query like (pseudo-SPARQL, equivalent for other languages etc.): ?subject wdt:P4969|wdt:P361|… ?print. ?print wdt:instance of (P31)/wdt:subclass of (P279)* print (Q11060274). In worst case the existence of this property would lead to those properties not being added. Probably we should make them more visible, dedicating a part of this awful guideline we have, Wikidata:WikiProject Visual arts/Item structure, to them. Maybe we could create a place on item pages where they can be expected by adjusting MediaWiki:Wikibase-SortedProperties. Would there still be any advantage of having this property proposed over them? --Marsupium (talk) 16:19, 2 November 2018 (UTC)
Well the reason I am adding more example items is because in the literature there are lots of examples where the relationship is key, although the nature of this relationship can be very different. I am keeping the property unspecific for this reason. So to be clear, first the unspecific relationship can be easily made, and more refined relationships can be created later. It should be eassy to upload notable prints and indicate their strongest relationship to other artworks. Jane023 (talk) 17:04, 2 November 2018 (UTC)
For example I mention Hollstein and Bartsch - I wanted to include Q numebrs and realized they don't exist on Wikidata (yet) except as people. Sigh. We need to make it easy to start and refine through iteration, not decide on some complicated hierarchy beforehand. Jane023 (talk) 17:09, 2 November 2018 (UTC)
@Jane023: Hm, I'm not sure if I get your point. Do you mean it is easier to remember a single property name? Otherwise do you have a concrete single example where using "notable print" instead of one of the existing properties is an advantage? --Marsupium (talk) 17:24, 2 November 2018 (UTC)
The obvious answer is use this property for the earliest or most popular documented print, rather than any of the multiple iterations of prints. We have no way of indicating a hierarchy of importance, especially for prints of specific locations. Jane023 (talk) 17:39, 2 November 2018 (UTC)
Now I understand it, thank you, I had a broader WD:N-like definition in mind and also read that from your text. Also the template fields have confused me a bit. If I understand you right now, what is in the subject item/Represents field should go to allowed values. And the domain (the subject, the item where you want to put the property on) you plan is obviously much broader than “work of printed art”, that's the subject/values. I still think the scope the examples suggest is too broad. --Marsupium (talk) 18:05, 2 November 2018 (UTC)
Hello Jane023 Marsupium. I didn't know this property derivative work (P4969) (many thanks!) and the proposed property seems indeed a subclass of this concept. As Marsupium explain, using the nature of the item/derivative work leads to same idea and logical structure. If we want to limit redundant properties, it may be a better choice. The other things pointed by Jane is about the confusion with prints in wikidata, where works (FRBR) and items (FRBR) are mixed. This one for example met again last night, on which I contributed and which has become a documentary monster: Melencolia I (Q1362177). Happy halloween! With the progress of contribution on prints we come to the point where we need an item for the work and other items for the materializations. And here, I understand the interest of the property, to avoid the possibility to add several versions of the same work as derivative works. Best regards --Shonagon (talk) 18:22, 2 November 2018 (UTC)
Yes exactly - and Melancholia is a good example. Think of this property a bit like notable work (P800) for people. I think that might help too. Jane023 (talk) 22:59, 2 November 2018 (UTC)
  • Symbol support vote.svg Support David (talk) 06:41, 3 November 2018 (UTC)
  • Pictogram voting comment.svg Comment Not sure that this is the right way round.
If we have an item for a print, (or for a "print state/print edition", cf map edition (Q56753859)), isn't the proper set of relations:
<print (item)> exemplar of (P1574) <print edition>,
<print edition> edition or translation of (P629) <print>,
<print> based on (P144) <painting> ?
That would seem more suited to what may well be a run of many-to-one relations.
What further does the proposed inversion, <painting> "notable print" <print>, give us?
And what would we mean by "notable"? What would make a print (or rather: print family, because that's really what we mean) notable or not ? Jheald (talk) 17:03, 5 November 2018 (UTC)
Please see the examples in the proposal. The idea of one-way identification (i.e. the print comes after the object) is of course a great idea to do, but we don't have all of those prints for many objects. In the case of paintings, we sometimes know the painting follows the print for example, but we still want the "notable print" on the painting. For painting series of the same subject (and for older series it is not clear whether these were made by the same master) there are often also more than one print, and it is unclear which print should be associated with which painting. This enables a fuzzy link when the relationships you suggest are unknown. Jane023 (talk) 17:24, 5 November 2018 (UTC)
@Jane023: Thanks, Jane. To your first point, however, this proposed property is to be item-valued. So it wouldn't be usable anyway, unless we had an item for the print.
Regarding paintings after prints: it seems to me potentially extremely confusing if this property will sometimes indicate a print that the painting is based on, if almost always it will be indicating a print that is based on the painting. Better to use <painting> based on (P144) <print> for the first case.
As to the case when it is not clear which print should be associated with which painting, I would settle for <print> based on (P144) <painting series> in that case -- it seems the most honest way to express the relationship. Jheald (talk) 17:50, 5 November 2018 (UTC)
Well I can't make prints any more or less confusing than they already are. I see no need to be scared of this property making things more confusing. It is in fact very useful to be able to link a painting to an associated popular print, especially when you can't determine what the print is based on at first glance. In the examples I gave, there are many 1-1 relationships, but of course there can be many-many relationships, where a series of paintings is based on a few prints, themselves based e.g. on various aspects of one popular altarpiece. We may not have many prints in Wikidata yet, but I hope this will change - see my comment under "motivation". I am not proposing to use this property when the relationship is not documented. The documentation should be in the print item (but it is sometimes included in information about objects sold on the art market). Jane023 (talk) 18:18, 5 November 2018 (UTC)
  • Symbol oppose vote.svg Oppose I'm sorry, but I really think this isn't a right way. Unlike what the motivation suggests all the aforementioned properties are there and completely sufficient to describe the relationship itself ("notable" aside). In my eyes there is no need to have a dedicated property for prints as opposed to any other kind of works. The "notable" part indeed seems to make it different somehow, but it isn't well-defined as from what I understand of the proposal so far. If there should be some need to qualify the relation of something to a print of it, then a qualifier would probably be a better way, maybe a derivative work (P4969) and object has role (P3831) combination. --Marsupium (talk) 23:37, 5 November 2018 (UTC)
Again, see my comment about notable work (P800). This property is to include the notable print(s) rather than just another way to link up any prints (which of course can be very many over the centuries for multiple editions, if we ever import bibliographic metadata). I would also be happy btw if that property was expanded to be able to be used on non-human items. Jane023 (talk) 12:14, 7 November 2018 (UTC)
  • Symbol oppose vote.svg Oppose per Marsupium last comment. The proposed property is overly specific and constrains the type of the object (to Print) but that is an inherent attribute of the object, it should not be carried by the prop. (By analogy, Mother is a worse prop than Parent because what happens if you link Mother to a male?). Marsupium and Jheald mention 4 existing props; Jane do you really want to create a 5th one and increase the confusion? What we need is more usage guidelines; and thank you for the excellent examples that move us significantly towards that. --Vladimir Alexiev (talk) 20:37, 14 November 2018 (UTC)
Thanks for liking my examples! I chose them precisely because I want to show the relationship of the item to a print. I find it interesting that you feel I am being specific, because this property is just one of many properties I would like to propose for prints, and this is the least specific of them. Your point that the properties derivative work (P4969), part of (P361), depicted by (P1299), published in (P1433) can be used instead is not true. None of these expect the object to be a print, which is the whole point. Secondly, the study of prints is extremely complex and the examples chosen are explicitly unsuited for derivative work (P4969), which would be very convenient indeed if all prints were well documented as to their origins. I think you will find that some engravers are considered artists in their own right, and many paintings are based on concepts known from "iconic prints" known for their popularity in politics, religion or art. So the same problem holds for depicted by (P1299) in the "chicken-and-egg" cases. The shell case is interesting because it is an exemplar of a period when shell collecting was at its peak. Lastly, whether something is part of a larger work or published in a work is useful, but has no indication in terms of being the "notable iconic image" part of the work.

Motivation[edit]

We have first line (P1922) and last line (P3132), but it's not possible to add quotes for anything else (in particular things that are only one line long). Qualifiers like page(s) (P304) and time index (P4895) would probably be used for indicating the point within the work that the quotation begins. In addition to use for statements, this would be useful as a qualifier for statements relating between works, like work sampled (P5707). Jc86035 (talk) 17:47, 12 November 2018 (UTC)

    @ChristianKl: The 400-character limit for strings should suffice for now; perhaps a complex constraint would be required for items with more than about 4 statements for this property, and statements with more than one qualifier for this property. If it's fine for Wikisource to host massive amounts of copyrighted quotes from TV shows and the like, the implication is that there's nothing wrong with the same thing being done here (and CC-0 probably wouldn't make a difference to that here). Jc86035 (talk) 15:29, 26 November 2018 (UTC)
    It is fine for Wikiquote only because that project allows non-free content that is used under fair use (see here, though that is not official policy). I do not believe Wikidata is ready to do so itself. Having said that, I am still supporting this proposal below, as I don't believe the fact that someone could use a given field to add copyrighted information is a reason not to have the property at all. There are plenty of valid use cases for public domain works, so I think the solution should be policing Wikidata's content for policy violations, not preventing this property. Also, I would note the existence of quote (P1683), which already allows quotations on Wikidata (but that property is specifically for use in references). Dominic (talk) 16:04, 29 November 2018 (UTC)
  • Symbol support vote.svg Support, though I think this raises other issues. How should we distinguish between a true excerpt and when a full work is short enough to be included in its entirety (e.g. a short poem, short speech, etc.). These are conceptually different, and we would not want to misrepresent a full work as incomplete. For example, I just checked and the entire Gettysburg Address can fit in a single statement (the character limit is now 1500, not 400). And I would note that we already have an inscription (P1684) property, which is essentially a full-text quotation of a very specific type of work. I also think enabling quotations from works implies we should have an equivalent, but separate, property for adding quotations of people or things, since the data is usually given in that context as well. I think there should be three separate properties in total: "excerpt (of work)," "quotation (of person)," "full text/transcript". Dominic (talk) 16:04, 29 November 2018 (UTC)

A structured Wikiquote would, in any case, probably require much more software development for Wikiquote than for Wikidata, seeing as all that's required on the Wikidata end is one property and imports, and we could make the property now; whereas structured Wikiquote would require a lot of interface changes to avoid massively disrupting Wikiquote contributors' workflows.

Motivation[edit]

I am starting this proposal because of a gap we have in our ability to describe cultural collections. I first asked a question about this at Property talk:P195#Museum objects' organizational unit?, but received no response. Currently, we can only describe a collection in terms of (1) the institution two which it belongs (collection (P195)) and (2) the physical location, usually building (location (P276)). What this misses is the organizational unit to which it belongs. That is, within many large institutions, the organization is broken into divisions based on topic area, time period, type of materials, and so on—and objects or collections often list the department responsible for them in their metadata. This concept is distinct from the location, because it is about organizational structure.

For a concrete example, the Rosetta Stone (Q48584) falls under the Ancient Egypt and Sudan Department in the British Museum—simply listing the institution and the location fails to capture that data, which we could add if we make items for the organizational units such as that museum department. I am using examples from NARA above, as that is the collection I am actually working on.

Though it is widespread, there is no standard name for this concept. At NARA, we call it the "reference unit". I can also imagine it being referred to as a "department", "branch", "division", or something else along those lines. Also, sometimes this might be the institution itself, if there are no divisions within it. I proposed "organizational unit" because that seems broadly descriptive, but I am open to alternative suggestions. Dominic (talk) 18:01, 19 December 2018 (UTC)

Discussion[edit]

  • @Dominic: Is this different to maintained by (P126), if something is desired in addition to collection (P195) (which can be applied hierarchically) ? Jheald (talk) 19:14, 19 December 2018 (UTC)
    • @Jheald: I see this property as somewhat different from that one's scope, since it is about the organizational subdivision with direct responsibility, whereas that one could reasonably always take the organization itself as value. I also think the concept of "maintained by" ("keeping the subject in functioning order"), is a little different, since this is more about a set of physical or intellectual responsibilities related to a collection. In my Rosetta Stone example, the Ancient Egypt and Sudan Department at the British Museum doesn't "maintain" the object, but they do things like preserve, catalog, and describe it. And, more to the point, they are listed in a "Department" field in the catalog metadata, so clearly that is relevant in some way. There is clearly a concept here that needs modeling, and I think it makes sense as something with scope limited to cultural heritage collections, though I am struggling a bit in defining it succinctly. Dominic (talk) 19:36, 19 December 2018 (UTC)
      • @Dominic: According to its aliases maintained by (P126) is also intended to cover "custodian", and in French "conservé par", so (like most property labels) the name should be read broadly.
Alternatively, if the collection is divided up hierarchically, with different organisational units responsible for different bits of it, a more 'Wikidata' way of representing that might be to create new sub-collection items for the different parts of the collection - eg "British Museum Ancient Egypt & Sudan collection".
But the present name is not good. Something to indicate what it is that the property is saying connects the item to the value is needed. "Responsible organisational subunit" might be better -- that could at least suggest the property is about the idea of having responsibility for things. Jheald (talk) 20:04, 19 December 2018 (UTC)
  • Looking at the properties we currently have on items that are statement-values of collection (P195) statements (excluding human beings) tinyurl.com/y8gnpjgm, it seems that at present we have 37 with maintained by (P126) statements, and 87 with operator (P137) statements. May be worth looking into these.
Current uses of maintained by (P126): tinyurl.com/yc98c3xl; current uses of operator (P137): tinyurl.com/ycs559lh

Motivation[edit]

Wikidata includes many software items. Wikidata can currently include a download link (P4945) for each software version identifier (P348). However, it is difficult to include download links for every published version and keep this list updated. Furthermore, various computer architectures may require different downloads. Thus, for a user seeking to obtain the latest version of software suitable for their architecture, they would be wiser to ignore the included download link (P4945) and go to the official website (P856). By including a link to a downloads page on Wikidata, allow the user to skip the step of searching the home page for a downloads link. Most software has a dedicated downloads webpage, although on some occasions this may be the same as the official website (P856). Daask (talk) 21:56, 2 March 2019 (UTC)

    1. Wikidata software version identifier (P348) information is not consistently up-to-date, and therefore not reliable or usable for those seeking to download a piece of software.
    2. Different computer architectures sometimes require different downloads. While a software version identifier (P348) can have multiple download link (P4945) qualifiers, there is no way to describe which software version identifier (P348) is which, except by encoding this information in the URL. In other words, since software version identifier (P348) is a qualifier, it cannot have qualifiers of its own.
    3. This is one of the most vital and useful pieces of information about a software application, which is frequently searched for by users.
    4. There is no current property which is suitable to provide the same information. download link (P4945) is a qualifier, not a property.

Motivation[edit]

Women Writers in Review is a collection of 18th- and 19th-century reviews, publication notices, literary histories, and other texts responding to works by early English-language women writers. It is published by the Northeastern University Women Writers Project with support from the Digital Scholarship Group at Northeastern University Libraries, and grant funding from the National Endowment for the Humanities. A digitized evaluation of the reception of these works will enrich the understanding of the data, not just for this collections, but other scholarly collections from around the world as well.. Rosiestep (talk) 21:56, 2 May 2019 (UTC)

Discussion[edit]

An example would be: review score (P444) of "Review of A View of Religions" (Q????????) which is a review of "A View of Religions" (Q38227783). What this is meant to do is capture the relationship of the review score (e.g. a rating) of --> the periodical review of --> a literary work. The "review score" or any other associated property we listed would belong with the review and not the work it reviews.
Some facts and definitions regarding Women Writers in Review project:
There are 74 authors, who have published 198 works, which were reviewed by 112 different periodicals.
These reviews include: literary reviews, theatrical reviews, and so forth.
Review scores (ratings) include: Mixed, Very negative, Somewhat negative, Very positive, Somewhat positive, and Neutral or no evaluation.
Reviews are defined as: TEI-encoded transcriptions of individual texts, including data about their sources, and pointers to any referenced works or authors
Sources are defined as: or the historical periodicals/books/etc. in which the reviews were originally published
Works (shorthand for “referenced works”), or the distinct textual creations which are referenced in the reviews

@Rosiestep:, if these work for you, can you update the examples in your proposal? - PKM (talk) 23:00, 8 May 2019 (UTC)

if User:Rosiestep is happy for this to be what her proposal becomes -- I think it is not what she originally had in mind. @PKM: It would seem that we are clearly identifying this as a proposal for book (film, music, art, etc) reviews, rather than for a review article (Q7318358) or any other kind of review. The specificity may well be a good thing. Are we relaxed that main subject (P921) works for the rest? Jheald (talk) 00:20, 9 May 2019 (UTC)
See, that's exactly what I meant. If the intention was for book reviews (as hinted by the properties mentioned in the proposal), I'm fine with it, but it's hard to tell because of a lack of examples in the proposals (I have tagged multiple book reviews, I could fetch some!) and what amounts to overdescribed purpose. If the property is actually intended for review article (Q7318358) rather than book review (Q637866) (we don't seem to have a "movie review" item...), then this proposal is exactly what main subject (P921) is meant to handle.

I'd appreciate any advice on how to proceed or re-write this proposal. --Rosiestep (talk) 15:18, 10 May 2019 (UTC)

@Rosiestep: Okay, I think what you're talking about above is not a property proposal. A property proposal, in the sense of property proposal pages like this one, is quite a specific thing: namely a proposal for a new "verb" to go into statements of the form <subject> <verb> <object> , to allow one to say something about a particular Wikidata item (the subject).
The discussion you seem to be wanting is much broader, namely how to model "Women Writers in Review" more generally, and the texts contained within it.
I propose first to re-write the proposal above to be just about the verb "is a review of", since that is the kind of specific relation that these proposal pages are for, and seems to have attracted quite a lot of support above. --YesY Done.
Then I propose to create an item for "Women Writers in Review", and some model items for some of the review articles there that you've cited above, that will act as a basis that we can then consider and critique to see whether they could be expressed better. YesY Created: Women Writers in Review (Q63683777)
We might also consider creating a WikiProject page for "Women Writers in Review", as a central place to present summary statistics, and for discussion about data modelling and progress.
I hope that would seem agreeable to you. Best regards, Jheald (talk) 20:36, 10 May 2019 (UTC)
I have created some items: The Belfast Monthly (1810) on Aikin’s Epistles on Women (Q63684439), The Belfast Monthly Magazine (Q63684444), Epistles on Women (1810 edition) (Q63685444), Epistles on Women (Q63685268). They're not perfect, but they're sufficiently developed they can give us a solid enough basis for discussing how best to represent such sorts of items, relationships between them, and different aspects of the Women Writers in Review collection.
If the item for every book review includes the statement collection (P195) = Women Writers in Review (Q63683777), then it will be easy enough to write queries to analyse any collective aspects of the items in the collections; and the works they are reviews of; and those works' authors -- once items are created for each of the constituents of those sets of things. Jheald (talk) 22:29, 10 May 2019 (UTC)
The part of your project that I am least sure how to model is that corresponding to review score (P444) -- how highly the work was rated by the review.
Conventionally this is a property that sits on the item for the work, see eg Q2377#P444: so one way to represent the WWiR assessment of the review might be:
Epistles on Women (1810 edition) (Q63685444) review score (P444) "5/5"
with qualifiers:
review score by (P447) = The Belfast Monthly Magazine (Q63684444)
publication date (P577) = 1810
sourcing circumstances (P1480) = <WWiR assessment>
(better than determination method (P459) ?)
statement is subject of (P805) = The Belfast Monthly (1810) on Aikin’s Epistles on Women (Q63684439)
and referenced by
reference URL (P854) = https://www.wwp.northeastern.edu/review/reviews/aikin.epistleswomen.belfastmonthly.1
retrieved (P813) = 10 May 2019
One thing that I have a bit of unease about is that P444 requires a numerical score -- but the original review didn't give a numerical score. An assessment of the review is made by WWiR, but that's not actually numerical either -- the different values for reception there [3] are in fact "very negative", "somewhat negative", "mixed", "somewhat positive", and "very positive", plus "neutral or no evaluation". If anything, this is more like a scale of -2 to +2, if one should represent it numerically at all. Is it fair and/or appropriate to represent it as a score from 1 to 5 ? I am not sure, even if a P1480 qualifier arguably gives some cover.
But I do like the way that this would group all the review scores together under the reviewed item. In fact under this approach you wouldn't even need to create items like The Belfast Monthly (1810) on Aikin’s Epistles on Women (Q63684439) unless you particularly wanted to, or unless there was particular additional information about the review that you wanted a place to record. And you could use the P1480 tag to gather together reviews from the WWiR project for query purposes.
Any thoughts from people on this modelling? Jheald (talk) 23:22, 10 May 2019 (UTC)
Neither determination method (P459) nor sourcing circumstances (P1480) have any business being there. What you really wants (as far as I can tell) is reference has role (P6184) book review (Q637866). Circeus (talk) 15:05, 11 May 2019 (UTC)
@Circeus: It seems that, fundamentally, User:Rosiestep is interested in recording the positivity or negativity of the review, as assessed by the WWiR project. It does seem to me that review score (P444) is our best bet for doing that. But as the original 1810 review didn't come with the helpful statement "Blockbuster -- don't miss: 5* ", it seems to me we do need to qualify any such 5/5 rating with something to point to where that number has come from, what it may mean, and how it has been assessed -- i.e. to link it to an item standing for the WWiR assessment model and methodology. IMO determination method (P459) would be legitimate, because the WWiR methodology is how the 5/5 has been arrived at. But I slightly prefer sourcing circumstances (P1480) as indicating this statement has particular issues associated with it.
This way also has the advantage that one can see how positive or negative all the reviews for a work were, all at a glance in a single place. (And it transfers easily to infoboxes, which is probably why we instituted this approach in the first place.
It's a fair point that it's reductive and uncultured to try to reduce what may be a subtle and engaged discussion of the work to a single numerical score. But it's useful, and that's effectively what WWiR have done, so I don't see any reason not to reflect it here. It's equally true that there will be reviews that we don't have an external assessment of positivity for; and even in the WWiR corpus there are items like notices of works, that give no effective view of them. In such cases we could still use the above data model, even with no numerical score, by setting review score (P444) = somevalue or P444 = novalue and using the same qualifiers. Alternatively, it has been suggested in the discussion at WT:BOOKS to use described by source (P1343) = the magazine that carried the article, with statement is subject of (P805) pointing to an item for the review itself, to which could be added object has role (P3831) = book review (Q637866) along the lines of what you suggest. Jheald (talk) 16:06, 11 May 2019 (UTC)
My bad. I thought you were discussing actual review scores such as those documented by Template:Video game reviews (Q6354287) (as opposed to stuff like Metacritic (Q150248)'s metascore). Circeus (talk) 23:40, 11 May 2019 (UTC)

@Abbe98: agree. I dont see that Dramaten gives us a query a problem (if it is stable) more who should have what data. I think we need to start having a dialogue inside Wikidata and with external parties like Dramaten
  • Should wikidata has everything? - my answer No
    • Is it ok to use mapping relation (Q60817979) and a qualifier close match/narrow match- I see no problem, but the question is more why do we add them. When LOD get more mature we will meet this problem all the time. I can see it with churches in Sweden that domain experts like Swedish National Heritage Board (Q631844) always will have a more "mature" model that is too complex for Wikipedia
  • Should Wikidata has the persons and major plays and we tell the domain experts to join our echo system setting up a Wikibase (Q16354758) - see my presentation last week(GITHUB) were I hope this is the way forward but today I feel its not realistic as its a mismatch between complexity of the concept/Wikibase product maturity/#LOD skills at domain experts
- Salgo60 (talk) 09:48, 6 May 2019 (UTC)
@Salgo60: your comment is not related to my concern. The identifiers look fine to me but the query is defiantly not stable and will break sooner or later. It would in almost all cases just be the Wikidata label URL encoded, if applications would like to create such links they could do it on the fly. Linking to unstable query links is the opposite of Linked Open Data. Abbe98 (talk) 12:07, 6 May 2019 (UTC)

Proposed as a result of the discussion to un-deprecate comment (DEPRECATED) (P2315) property. copyright status (P6216) statements can get quite complicated and current format might not be able to capture full reasoning behind some of the decisions. Especially with determination method (P459) qualifier, there is a fine balance between too specific items and too broad ones. This property would allow us to keep on using generic reasons in determination method (P459) qualifier while allowing us to be more precise with this free-text clarification. My first choice was to resurrect comment (DEPRECATED) (P2315) property, but I was convinced that a new narrow scope property might be better. --Jarekt (talk) 02:45, 8 May 2019 (UTC)

Yair rand, Yes this is not structured data and it is not meant to be. It is meant to help other users that come after us to understand why we picked some combination of parameters. For example we claim that Statue of Liberty (Q9202) is in Public domain in the US because it was published before more than 95 years ago. That is as far as structured data will take us. However for future users that might be puzzled by that statement it could be useful to explain that "publication date is assumed to be 1886, when statute was placed in the public location without restriction on making copies". A free text explanation would be preferable to adding publication date (P577) to the item.

TV Tropes (Q2537428) is a database of cultural works (movies, TV shows, manga, books, video games, media franchises) and associated trope (Q843227) and other narratrive concepts.

Do we want one property, or one per concept? I see three possibilities:

One property
  • TVTropes ID
Two properties
  • TVTropes trope ID (/Main/)
  • TVTropes person ID (/Creator/)
  • TVTropes work ID (/[Manga|Series|Film|Franchise|VideoGame|Literature|/<id>])
Several properties
  • TVTropes trope ID
  • TVTropes person ID
  • TVTropes TV show ID
  • TVTropes manga ID
  • TVTropes film ID
  • TVTropes video game ID
  • TVTropes book ID
  • TVTropes franchise ID

Discussion[edit]

  • I support the inclusion of TV Tropes. I'm however not quite sure about the best way to do it, as well, as their URL structure is a bit chaotic. Creating separate properties for each distinct category on the site could IMO result in too many properties, since in addition to the ones you mention, there's also categories/"namespaces" like /advertising, /comicbook, /ComicStrip, /Roleplay, /Ride, /WebAnimation, /WesternAnimation, /Myth and even /Disney (see here for a list). And when an animated film like Pinocchio (Q4341553) for example isn't located in the same namespace as other animated films, but under Disney/Pinocchio, the site doesn't make it easy to create well-definied separate properties. I like your second option - separate properties for tropes (/Main), persons/companies (/Creator) and works (/*). But unfortunately, it seems among those work namespaces, not all contain just works. /Music for example seems to also contain singers and bands (see here), meaning persons aren't all contained in the /Creator namespace. There's also the /UsefulNotes category, which contains people, places, events and much more, along with works they appear in. Those could also be interesting to include, but don't fit into one of those three categories. A single property might be more unwieldy, but has the advantage that we don't have to care about all the intricacies of what kind of entries are contained in each namespace and that entries for persons are spread across various namespaces. --Kam Solusar (talk) 21:39, 15 May 2019 (UTC)

  • Symbol support vote.svg Support with a single global id property. No need to bother with splitting away the namespaces (because that's really what they are), especially as we won't need to have a wiki id the way we do for Fandom and Gamepedia articles. Circeus (talk) 19:22, 16 May 2019 (UTC)

Motivation[edit]

This property seems like a reasonable way to complete the set between Gamepedia article ID (P6623), Fandom Wikia article ID (P6262) and Fandom wiki ID (P4073). It's kinda surprising it was forgotten given the differences in coverage that may exist. Circeus (talk) 19:44, 16 May 2019 (UTC)
