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 (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.

On this page, old discussions are archived. An overview of all archives can be found at this page's archive index. The current archive is located at 2018/10.

A number of digitisation projects have uploaded images to Flickr, using Flickr tags to group images from particular sources or relating to particular subjects. It would be useful to record these, and provide easy linking to the corresponding images. Jheald (talk) 15:02, 18 May 2018 (UTC)

  • Symbol oppose vote.svg Oppose seems to be the wrong datatype if not limited to the British Library tags. String is what we use for similar (e.g. Twitter tags). If the use wont be limited to a single item, it shouldn't be an external identifier either (compare with some other classifications).
    --- Jura 18:08, 20 May 2018 (UTC)
    • @Jura1: It's an identifier, it's external => it ought to have an external identifier type. Much better for it to appear below the fold than cluttering up the main section of statements on an item. If you want to record whether it is generally 1-to-1 or not (and, yes, it's probably not, if one starts going beyond institutional tagging), that's what constraint statements on property pages are for. Jheald (talk) 18:18, 20 May 2018 (UTC)
    • I agree with you, but that's not the conclusion from the discussion about the string datatype conversion. Besides, mere GUI things can be changed otherwise. So to be consistent with others, it should use string datatype.
      --- Jura 18:21, 20 May 2018 (UTC)
      • @Jura1: A particular aspect of our GUI could be changed, but in this case its unlikely -- how should the GUI distinguish string-valued statements for genuine strings that ought to appear above the fold, from string-valued statements for external identifiers, which ought to appear below the fold. Much better to make all external identifiers external-identifier valued.
Even more difficult, how are external applications supposed to recognise strings that refer to external identifers, if they are not external-identifier valued? For example, Reasonator. The value of this property ought to be in Reasonator's external links box in the right-hand column. But how is eg Reasonator supposed to know that, if the property is string-valued rather than external-identifier valued?
If other properties have been given unhelpful types, the place to start changing that is here and now. So I stand firm for making this external-identifier valued, because it is an external identifier, and I believe it is helpful to external applications to mark it as such. We should remember that "consensus can change". If external identifiers haven't been given external-identifier type, that nonsense has gone on long enough, and we should end it. :::Can you give a link to the earlier discussion on this? What were supposed to be the conclusive benefits of giving external identifiers a type other than external-identifier? Is any application in the wild relying on this distinction (as opposed to being degraded by it, like Reasonator) ? And if this is about reasonably consistent single-valuedness, why is that not more effectively indicated by the explicit constraint statements on |the property? Jheald (talk) 19:29, 20 May 2018 (UTC)
It's just not the outcome of the discussion. Datatype alone isn't necessarily a good indicator for GUI construction. Currently this mixes social media accounts of a person with third party identifiers. Depending on the presentation, this can look bad. I asked our developers to look into some of the GUI issues at Wikidata. Obviously, interface things are always top priority for them ;)

There's scope for perhaps up to 100,000 such categories on Commons, maybe more. Jheald (talk) 09:39, 23 July 2018 (UTC)
Some background about the machine tags at .
Not sure if we should even link to Flickr in the example. Shouldn't all these images just be on Commons? Multichill (talk) 11:21, 23 July 2018 (UTC)
@Multichill: 1. Stats: We currently have about 40,000 images on Commons from the BL scans, out of about 1 million on Flickr. For images scanned from Internet Archive books, we have about 480,000 images, out of about 5.25 million on Flickr. We have about about 250,000 images from the BHL, out of an unknown number, mostly linked directly to the BHL website, though copies may exist on Flickr via the IA.
The issue with these pix (and the reason for those counts) is that metadata for these images is generally very very weak, generally extending no further than title, author, publisher, and date of the book the image was extracted from -- ie most usually nothing about what might be actually depicted in the image. Also, many of the images frankly aren't very interesting or of very high quality. For that reason the Commons community originally outright vetoed a bulk upload of all the BL images; instead those that have been uploaded have been uploaded selectively, and hand-curated by editors as they went along. Regarding the IA images, Fae has systematically uploaded those above a certain size, and left the rest. So that's why, in both of these cases, there are a lot more images still on Flickr than those so far copied to Commons.
Should we copy over the rest, particularly in view of Flickr's recent change of ownership, previous precarious financial position, and the recent repositioning of some other image platforms to turn against Commons images? Perhaps, but in the case of both the IA and the BL, we know where these images came from, we are on good terms with the institutions, and we could almost certainly obtain the images on hard drives if anything calamitous did happen at Flickr. So there is probably no pressing reason to change existing Commons practice. (Though I do still hope to upload 50,000 of the BL images that depict maps, for which currently underway). But it would be useful to be able to systematically link to the corresponding image-sets on Flickr, from Commons categories for books, to see what other images may be available.
2. Machine tags. Is there a Dutch translation of the English Q7691305? Perhaps with a nice informative illustrative painting by Jan Steen (Q205863) ? :-)
Yes, I know what machine tags are. The metadata improvement project for the map images has even been systematically adding them. But there are a number of problems with them, the first being that they are hardly used, so Flickr doesn't really care about making sure that software updates don't break them. There are a number of ways of constructing Flickr URLs with them that one would feel ought to work, but then strangely don't. Even if a URL template can be made to work this year, that's no guarantee as to whether it would still work next year. In contrast the simpler regular tags tend to be more bulletproof. Also the machine tags and/or the searches for them munge spaces and punctuation in various ways, making it difficult to use many existing identifiers as machine tags.
But the real point is that, for what I really want, namely to return all the images from a particular book, the images already have tags for this, systematically added by the BL and the IA when the images were uploaded, so those are the tags I'm interested in. Nobody is going to take the time and bandwidth to add machine tags to 6.25 million images, simply to duplicate information that is already there. It's the current established regular tags for books and book-volumes from the BL and the IA that one would want to link to. Jheald (talk) 14:52, 23 July 2018 (UTC)
  • Symbol support vote.svg Support by analogy with other tag properties created and proposed, though it is very clearly evident that concerns about their creation overlap greatly at least when it comes to their datatype and their general worthiness of inclusion. On this former point, until we all agree to recast Twitter hashtag (P2572) as an external identifier, I support this property's creation as a string; on the worthiness of its inclusion, I sometimes wonder, given many of the examples presented here and elsewhere, whether a single unified 'tag' property is in order, seeing as most of them pertain to exactly the same topic whether viewed on Twitter, Instagram, Gfycat, or Flickr. Mahir256 (talk) 15:10, 23 July 2018 (UTC)
  • Symbol support vote.svg Support I'm a bit unsure: this is very similar to Twitter hashtag (P2572) but there are differences. Tags are no identifiers, so the datatype should be string, but tags serve a similar purpose like identifiers. Flickr tags were one of the first popular instances of folksonomy (Q494291), that's why I support this proposal. There are several more tagging applications, (e.g. see and we don't want properties for all of them but this must be decided case by case. -- JakobVoss (talk) 20:41, 15 August 2018 (UTC)

As noted on Wikispecies:

the Consortium of European Taxonomic Facilities has created a system of persistent identifiers for type specimens ( The intension is that the URI to the specimen will remain stable indefinitely, so we can link to type specimens without fear that the link will break.

The CETAF initiative creates "a joint Linked Open Data (LOD) compliant identifier system". The particpating institutions include the Royal Botanic Garden of Edinburgh, the Museum für Naturkunde, Berlin, The Natural History Museum, London, the Royal Botanic Gardens, Kew and the Royal Museum for Central Africa. Additional information can be found at the CETAF Stable Identifier Initiative Wiki.

AIUI, the intention is that data about type specimens should be stored on an item about the specimen, not the item about the taxon. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:40, 24 June 2018 (UTC)

    • CETAF IDs are in fact exactly what you advocate i.e. links to the specimens in the holding museum not a third party.

RogerHyam (talk) 15:12, 25 June 2018 (UTC)
      • No they are not, they are an unreviewed third party and this is problematic in nomenclature which requires serious review and checking prior to publication, ie peer review. Cheers Scott Thomson (Faendalimas) talk 15:33, 26 June 2018 (UTC)

For each of those three cases, please tell us which "third party" is being linked to? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 16:47, 26 June 2018 (UTC)

I did not say linked to, I said obtained from, and that it is a non reviewed assessment hence unchecked by scientific rigor. In anycase the first one has a second url on the page which is the museum whether its the correct specimen I do not know, the second is possibly linking to the correct specimen without evidence to show its correct, the third is a dead link for me so I cannot tell what its supposed to do. Cheers Scott Thomson (Faendalimas) talk 03:07, 27 June 2018 (UTC)
@Faendalimas: What you said was "better to use links to the actual specimen in the holding museum, not a third party". Furthermore, when told "CETAF IDs are in fact exactly what you advocate i.e. links to the specimens in the holding museum... CETAF is acting more as a standardisation body to get the museums to produce URLs with similar behaviours - basically Linked Data URIs with some agreed metadata attached.", you replied "No they are not".

I do not have an issue with the links. Its the authority of the information. I meant not "from" a third party. (If you copy and pasted my previous statement, I did not look, I must have left that word out, apologies for that). As in not obtaining the information from a third party. Rather than from the source. What I am getting at is that the information needs to be peer reviewed which online resources are not. I did figure there was a mistake in the url above I assumed you would fix it. Cheers Scott Thomson (Faendalimas) talk 15:16, 27 June 2018 (UTC)

  1. Botanic Garden and Botanical Museum Berlin-Dahlem (Q163255)
  2. Finnish Museum of Natural History (Q3329689)
  3. Institute of Botany (Q30255205)

So how could we restrict this URI to this institutions. Most of the URIs will not represent a type specimen (Q51255340). How to use this URIs here?

Hi Roger, nice to see you here. If I understand the proposal right, it involves the creation of items to get taxonomic type (P427) working. So we need to define how to map the metadata values to our properties. I created P01069419 (Q55196248), P01069417 (Q55197790) and holotype of Ouratea sipaliwiniensis (Q55200035) as a base for discussions. --Succu (talk) 18:53, 25 June 2018 (UTC)
I'd rather not get into recreating nomenclature. It is a intellectual exercise akin to the jigsaw puzzle in Laura & Hardy "Me and My Pal" (YouTube) - We will be at each others throats and the biodiversity of the world destroyed before we finish the task. Really a type relationship has to include literature and a lot of complexity that is of use to a small specialist audience and just confuses everyone else. If someone wants to know the type of a taxon they can read the literature in the Taxon Name (Property:P225).
It appears Wikidata is building a single consensus taxonomy. If we had a single property that was "has Voucher Specimen" or similar then we could add properties to taxa based on the identifications by experts in museums. e.g. Q557928 "has Voucher Specimen" would be possible. Perhaps I should be proposing a different property but I'm new to the wikidata thing. RogerHyam (talk) 10:18, 26 June 2018 (UTC)
Wikidata is not building a single consensus taxonomy. The contrary is true. A lot of users have difficulties to accept this. ;) --Succu (talk) 17:48, 26 June 2018 (UTC)
Hi Succu. Could you give an examples of multiple taxa (taxon concepts) with the same full scientific name in Wikidata. I'm a bit ignorant on this and need to understand how it is being represented. RogerHyam (talk) 08:15, 27 June 2018 (UTC)
E.g. we implemented APG I to IV. See the references for parent taxon (P171) at Cactaceae (Q14560): Maybe this is not exactly what you expected. Please note note this discussion too. --Succu (talk) 17:43, 27 June 2018 (UTC)

Pictogram voting comment.svg Comment I'm not sure that the name of the property is good. It may be better to have it as "Museum Specimen ID" or "Voucher Specimen ID" and then have a recommendation that these are CETAF compliant URIs. This way we can have stable links to many specimens that have been determined to belong to a taxon by experts and, if people are good with their data markup, most of these will be expandable into images and geolocations etc. RogerHyam (talk) 15:21, 25 June 2018 (UTC)

  • Symbol support vote.svg Support David (talk) 15:25, 25 June 2018 (UTC)

Pictogram voting comment.svg Comment that this is already so confused shows why this is not a good idea in concept. You cannot call the type specimen a voucher specimen or a museum specimen per se. Yes a type is both of those but so are many other specimens. The type is a special case of a voucher or museum specimen as it is the only specimen that the available name of a taxon is attached to. No other specimen has this. It is the specimen upon which the name is established. It has major import. I agree it is only of major interest to a specialist minority, ie taxonomists mostly, but you cannot undervalue it, nor have it proposed in a way that any museum specimen or voucher could be called this. Only the original description or a peer reviewed taxonomic review should be used as the reference of the type specimen. As such they should be listed with reference to these articles and only this way. Then there is a clear reference. Online resources are not reviewed as such and are not reliable when it comes to types. This will introduce potential error in this area of nomenclature that is extremely exacting. Cheers Scott Thomson (Faendalimas) talk 15:18, 26 June 2018 (UTC)

I agree. I created P01069419 (Q55196248) from the details given in Novitates neocaledonicae V: Eugenia plurinervia N. Snow, Munzinger & Callm.

No; it was reverted with the comment "to restore coordinates, as previously"; and that was because, as well as your declared reason for editing, you also - yet again - re-added coordinates saying that the object is in New Caledonia, on the opposite side of the planet to its actual current location.

You are moving a bit fast for me to keep up, so please forgive my request for clarifications. Also, please forgive my lack is wiki etiquet if this is the wrong place for these comments.

It would be fantastic to load up all our typification information from the Meise Botanic Garden to Wikidata, but can you point me to a place that describes how?
In this property proposal there are no authority names. This is essential due to homonyms, but where possible they should be linked to people somewhere. However, does this cause problems when linking these data to other Latin names in Wikis that don't use authorities?
I’m sure there are errors in the data, such as there being two holotypes, fixing these is a motivation to expose the data. Does this work for you?
There also needs to be a field that tells you what sort of type it is holo-, lecto, iso, para, neo, etc. Do you want a full list?
The National Botanic Garden of Belgium changed its name a while ago, can I just edited this wikidata entry?

Qgroom (talk) 04:45, 27 June 2018 (UTC)

I wish there was an easy answer to this. I would love to see a proposal that actually did types the way they should be, with all the appropriate metadata included, utilising the correct terminology as accepted in the science and discipline of taxonomy and nomenclature. Alas we do not get this we get rather hit and miss efforts. If someone wants to try and create a property with all the needed attributes, obtaining data from reliable resources I would be happy to help. The same types of properties I create already in museum databases as a museum curator. The same ones I already use as highly published taxonomist and a nomenclatural specialist. You want us to use this material at Wikispecies Andy?? then do it right. I would support this if it was done correctly Andy. Cheers Scott Thomson (Faendalimas) talk 04:56, 27 June 2018 (UTC)
I think there are a few people in the CETAF community who could help get this right. Though personally I find it difficult to discuss these things in a chat page and I'm not sure how decisions are made here. Nevertheless, I'd really like to make this happen. Qgroom (talk) 06:11, 27 June 2018 (UTC)
"I would love to see a proposal that actually did types the way they should be, with all the appropriate metadata included" Then you are in the wrong place. This is a proposal to create a property to hold one type of identifier-URL. The only arguments you have presented about it are either easily refuted (see "third party links" discussion, above. or are merely vague hand -waving and appeals to authority, with no substance. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:34, 27 June 2018 (UTC)
My comment here was a generalized one only brought up in reference to the above comment. Its not a direct reference to the proposal here at hand. So yes I know this is not the right place. I think the whole structure of how types are presented is inadequate. My point was that unfortunately many proposals are attempts to gather information from online resources for ease of mass import with no respect to the exacting nature of taxonomic data and metadata permitting potential mistakes. These online resources are not authorities on the taxonomy of species. What is the point of data if there is no evidence inherit that demonstrates it has been tested for accuracy. For taxonomic data I want to see us produce useful information not page upon page of unreliable rubbish. Your difficulty Andy is you do not use this information. You are presenting it, but not using it. Much of the informatics being presented, not necessarily by you I am generalizing now, has no guarantee, therefore it has no use in taxonomy. So what is it then except page upon page of what exactly? Cheers Scott Thomson (Faendalimas) talk 15:30, 27 June 2018 (UTC)
@Qgroom: for "a field that tells you what sort of type it is", please see P01069419 (Q55196248); but note also the issues with that data model, which I have raised here. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:34, 27 June 2018 (UTC)
I think I get it. So in your example P01069419 (Q55196248) you would replace the URL (P2699) with this proposed CETAF specimen ID property.  – The preceding unsigned comment was added by Qgroom (talk • contribs) at 15:29, 27 June 2018‎ (UTC).
@Qgroom: Precisely. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 15:36, 27 June 2018 (UTC)
Could you please explain why this substitution is useful? What we (=Wikidata) gain from this change? --Succu (talk) 20:45, 27 June 2018 (UTC)
I suppose the question is why we need a subcategory of URL that is specific to CETAF specimen ID. Well from my point of view, which is quite ignorant of the workings of Wikidata, having the distinction is useful because the CETAF specimen ID points to a great level of stability and functionality than a standard URL. I'm not certain this is entirely necessary, however, it is particularly useful to have one URI that uniquely represents the digital representation of the physical specimen. People could link to many different image files or website all representing that specimen. These might be labelled in all sorts of ways and be derived from all sorts of places. Yet it is much better that there is only one standard way to refer to the physical specimen. Qgroom (talk) 13:51, 29 June 2018 (UTC)

missing VIAF components[edit]

Go to, sort by col "property" and look for "!!!". This shows VIAF sources that don't have corresponding WD properties (which should be marked as VIAF component (Q26921380)).

This includes:

  • National Library of Luxembourg
  • National Library of Estonia
  • National Library of Lebanon
  • National Library of Morocco
  • National Library of Iceland (NULI)
  • Perseus (ancient places)
  • Syriac Reference Portal
  • Flemish Public Libraries

The total number of ids is about 250k. I haven't researched whether these authority datasest are available online. Do you think we should create properties for them? Any volunteers to help me with the research?

Also: do you think we should add col "code" to WD in some way? A few of these are available as third-party formatter URL (P3303), but most aren't. It took me a few hours to correlate all VIAF-component sources against WD, and it wasn't fun.

Pictogram voting comment.svg Comment There are a lot of WWII history websites; this is a mediawiki site, so a sister in a sense, but can you give a bit more detail on why you think this one is important or special? ArthurPSmith (talk) 19:46, 11 September 2018 (UTC)
That was my thought, too. How reliable is this site? Unfortunately, these kind of sites often seem to attract the kind of people who aren't satisfied with information provided by historians and try to spread their own version of the "truth" (revisionists, apologists, misled Wehraboos...), so it's important that there is some kind of review and quality control. But I can't find any hint that there are historians involved or that there is some kind of review of the content by experts. Looking through the wiki, there seem to be many pages that are pretty empty, others were obviously imported from some other wiki (edit comments, missing templates, etc.). And their Recent Changes page doesn't show a lot of activity. Doesn't look like a high quality source of information to me. --Kam Solusar (talk) 01:28, 12 September 2018 (UTC)

I am working on importing the Sami bibliography from the Norwegian National Library (around 26,000 works) to Wikidata. Almost all of the works use this classification system in addition to Dewey Decimal Classification (P1036), so I think it would be good to have this as its own property to get as much completeness as possible to the imported items. Since I haven't started the import yet, the examples don't link to existing items, but to the entries for books from the bibliography in their API.

The Getty Iconography Authority has additional topics compared to Iconclass, also less eurocentric. It uses amongst others the English Wikipedia (example) and Iconclass (example) as sources. It can bring us IDs and new items for some stuff missing at all or lacking an ID. It is connected to the other Getty Vocabularies, brings their known structure of hierarchy, terms etc. and are anticipated to be available in the future also as LOD and via SPARQL.[1] --Marsupium (talk) 15:57, 10 October 2018 (UTC)
