On Wikipedia we have a lot of experience breaking down large amounts of work into smaller chunks that can be completed. Examples of this are the windmill project on the Dutch Wikipedia and the many lists of historic buildings that were created for Wiki Loves Monuments (Q1353202). For paintings we can use the same strategy: We break it down into smaller parts that can be handled and then we can utilize Wikidata to celebrate the sum of all paintings through linked open data!
All or everything is too broad and has no limit. This limit is to be able to handle the processing of the data - let's not overwhelm ourselves (yet). The scope can always be expanded - in the future we will have the sum of all sculptures, drawings, you get the picture! The scope of this project is notable paintings. A painting is considered notable if one of these options is true:
- The painting is in a notable collection of a museum, library, archive (e.g. a painting in the Metropolitan Museum of Art)
- The painting is made by a notable artist (e.g. Van Gogh painting in a private collection)
- Paintings in scope meet notability guidelines in Wikipedia, as they are notable for being in a notable Galleries, Libraries, Archives, and Museums (Q1030034) collection, are painted by notable painters, and/or generally have secondary reliable source documentation written about them.
- GLAM is an acronym and means galeries, libraries, archives and museums, but in a broader sense includes also public buildings like castles, town halls, administrative buildings or religious buildings like churches, cloisters, temples etc. that can hold paintings or wallpaintings and other pieces of art.
- Use the guidelines of item structure when adding data to each painting entry. Think of it like a collections management database of information.
- If you come across an item (i.e. a painter, medium, collector) that does not exist create it please on Wikidata. (Click the red link :) )
All institutions have metadata of some sort - this data is super important to making the most out of this project. Our dream is that all GLAMs open their collections metadata under a Creative Commons Zero (CC0). This allows us to easily upload data to Wikidata using automated processes and saves us time and people power to focus on other parts of the project. It also means that those GLAMs who have released that data, like the Rijksmuseum (Q190804) already have their data on Wikidata. You can learn more about why you should open your data CC0 here. Right now, only a small group of institutions have done that.
But my data is published under a CC-BY-SA license! We can't use it through auto mass import because it is incompatible with the license of Wikidata. It's a restrictive license for data and goes against our mission of providing free, reusable data.
For data in databases in the USA we have a similar copyright situation as reproductions of 2D artworks: It's (probably) in the public domain. See the Wikimedia Foundation’s preliminary perspective on the legal issue of database rights. So from a legal standpoint we're probably save to copy data from a museum in the US, just like we can copy the reproductions of old paintings. Just like with copying reproductions, we rather do it together with the GLAM than without their knowledge and consent. See also this overview of cases studies of working together with GLAMs.
We haven't released our metadata, but we do have some of our collections online - Great! Then we can slowly work on manually putting your artwork on Wikidata. Please list it below by country and help us by adding your data manually on Wikidata. It's a long process, but, better than not having your work represented.
Getting the data for all paintings and importing this data and curating the items is a lot of work. To make this manageable we subdivide all paintings in smaller sections by collection (P195). This way people can focus on one collection, get it to a certain standard and than move on to another collection. For this to work every painting needs to have collection (P195).
Here are a few ways you can get started in helping out!
Help bring these lists down to zero
Wikidata already has quite a few paintings. You can help by adding information to these paintings.
Here are some other lists you can help with:
- All paintings without creator - Top missing properties by number of sitelinks/P170
- All paintings without inventory number
- All paintings without collection - Top missing properties by number of sitelinks/P195
- All paintings without date
- All paintings without material - Top missing properties by number of sitelinks/P186
- All paintings without depicts - Top missing properties by number of sitelinks/P180
- All paintings without genre
- All paintings without image
Notes: On Wikidata, private collection (Q768717) is a valid collection (P195) and those paintings in private collections should be labelled as such. These will occasionaly have no inventory numbers. You can give it inventory number (P217) with "no value" snak if you are absolutely sure the collection does not use any inventory numbers. Wikimedia commons recognizes "oil on canvas" and "oil on panel" in the artwork "medium" field. On Wikidata, the material used (P186) should be filled with two items; oil paint (Q296955) and also to canvas (Q4259259) or to "panel". The depicts (P180) can refer to specific buildings if a cityscape, or to people, if a portrait, but it can also be something less specific, such as "forest" or "abstract art". Typical genres are landscape art (Q191163) or portrait (Q134307).
Items without claims
Add collections that need to be worked on by country
We also work on things based by country, which is then broken down into institutions within that country. Please add your institutional data here. Just copy and paste from another page if your page is a red link and modify the markup as needed.

It's possible to keep notes on individual collections, see the full list of collections here: Wikidata:WikiProject sum of all paintings/Collection.
Item structure to describe paintings on Wikidata
Paintings should be properly described. See Wikidata:WikiProject Visual arts/Item structure to find a full list of properties. We'll highlight some important ones for paintings here. The two statements every painting here should have:
- instance of (P31) → painting (Q3305213) (or one of it's subclasses) so we can find the painting
- collection (P195) so we can subdivide the work in smaller parts
And to make it a good start painting item add the following statements:
|property||Data type||description||required||missing values|
|creator (P170)||Item||maker of a creative work or other object (where no more specific property exists)||yes||check|
|inception (P571)||Point in time||date or point in time when the organization/object was founded/created||yes||check|
|inventory number (P217)||String||identifier for a physical object or a set of physical objects in a collection||yes||check|
|material used (P186)||Item||material the subject is made of or derived from||yes||check|
|location (P276)||Item||location the item, physical object or event is within. In case of an administrative entity use P131. In case of a distinct terrain feature use P706.||yes||check|
Questions, issues? Just ask on the talk page (click "Discussion") or send out a tweet with the hashtag #glamwiki.
Add painters (aka creators)
To link paintings to their creators, we need to have items about these painters. You can help create missing painters. Good sources for finding painters to create are:
- Getty Union List of Artist Names (ULAN ID (P245)) - http://www.getty.edu/research/tools/vocabularies/ulan/
- RKDartists (RKDartists ID (P650) - https://rkd.nl/en/explore#query=
You can also use Mix'n'Match to match existing items to these authority control databases.
These sources usually contain enough information to build a new item:
- Add the name as the label, add variants as aliases.
- Set the label with country and occupation
- instance of (P31) → human (Q5)
- sex or gender (P21) → male (Q6581097) / female (Q6581072)
- occupation (P106) → painter (Q1028181) / ...
- country of citizenship (P27)
- date of birth (P569)
- place of birth (P19)
- date of death (P570)
- place of death (P20)
Catalogs document the paintings that used to be in public collections, were lost to theft or accident, sold for unusually high prices (we can't yet include data about prices paid), or which were notable for some other reason. Old catalogs help trace the provenance of paintings as to owner, attribution or location. You can add items for catalogs and add one catalog number to one painting, or model entire catalogs. The numbers of the artworks used in catalogs is open data. For older paintings, we can just fill these in. For catalogs listed by publisher or institution, see c:Category:Catalogs of art by institutions.
- Use property catalog code (P528) for the catalog number
- Use the qualifier catalog (P972) for the catalog (if the catalog doesn't exist create an item for it)
Try to find the "recognized" art historian for the specific painter you are studying. If the art historian doesn't exist create an item for him/her, but first check the name using the Dictionary of Art Historians (Q17166797).

Improve all metadata for the oeuvre of one painter
After importing thousands of paintings, we notice that our data here is not always as clean as it can be. Sometimes creation dates of paintings are missing, attributions are not entirely correct, etc.
One way to help cleaning this up, is by focusing on one single painter's work, checking and improving the correctness and completeness of all her/his paintings we already have here on Wikidata.
Here's a list of the 100 painters with the most Wikipedia sitelinks and at least 10 paintings on Wikidata. Pick one and indicate you're working on his/her oeuvre!
We have different ways you can help out depending on your skill set and what you feel like doing. Simplified in three steps:
- Get the data
- Upload the data
- Curate the data
- Add content to Wikidata! Edit away :)
- Add inventory numbers
How chapters can help
- Chapter volunteers or personnel can help by reaching out to museums to get them to release their metadata for paintings into the public domain (CC0). You might already have existing contacts with museums and this might be the next project to do with them. Because we focus on metadata and not images of artworks we can work together with museums of contemporary art (mostly off-limits for other projects because of copyright restrictions). Over time we'll have case studies here of other museums who contributed to Wikidata and how that worked out. You'll be able to use that as an extra push to get a museum on board.
- Host events bringing together volunteers to edit painting content on Wikidata.
How GLAM staff can help
- Talk to your staff about opening up your metadata under a CC0 license. Then get in touch with us on the talk page or via Twitter hashtag #glamwiki and tell us that you've opened it. We'll work with you to make sure it's properly declared and accessible and then start the processing of uploading your data to Wikidata! Learn more here.
- Have events to support adding painting data to Wikidata manually and painting content onto Wikipedia!
The Sum of All Titles: If a collection is located in a non-English speaking country, then chances are that we don't have proper native titles for many paintings in the collection. If you can give us a list of titles per painter in your collection indexed by inventory number, we can add that information to existing items in Wikidata.
The Sum of All Portraits: For important portrait painters, often the sitter is unknown on Wikipedia. If you have identified sitters in portraits in your collection, or if you know whether a portrait was made based on a photograph or sculpture or some other pre-existing work, let us know!
To import datasets to Wikidata we need bot operators. The current import bots are all based on Pywikibot so some knowledge of that or of Python is a pro. It's also quite important you understand the dataset, not everything is in English!
Ready to import
We found several nice CC0 licensed collections that can be imported now by a bot.
- Finnish National Gallery (Q2983474) (Finland): api
- Minneapolis Institute of Art (Q1700481) (United States of America): metadata dump
- Davison Art Center, Wesleyan University (Q18342336) (United States of America): metadata is individually located on object pages
- M - Museum Leuven (Q2362660) (Belgium): data in Europeana
Please add your name to this list! Simply add a # at the bottom of the list followed by your signature (just type 4 ~ like this: ~~~~) and voila! :)

How this data is being used
Having all this data about paintings available opens up all sorts of creative reuse. Some examples:
- http://sum.bykr.org/ - The Sum of All Knowledge, a project to visualize the knowledge getting added to Wikidata, Wikipedia and Wikimedia Commons
- http://www.zone47.com/crotos/ - Crotos, a tool to browse works of art on Wikidata
- Wikidata Skim - A (very) limited replacement for Wikidata Query, with images
- For example, here are all paintings by Frans Hals
