Goal shared with the Wikidata community at https://lists.wikimedia.org/pipermail/wikidata/2015-July/006581.html

Let me be the first to say that Europeana wants to be part of this. We are already publishing everything in open data (which has provided much of the seed-information for the 'sum of all paintings' wikidata project) and have a strong organisational interest in being able to query Wikidata to integrate it in Europeana's database. (which requires, among other things, converting the current Europeana's hooks to dbpedia, and a production-grade SPARQL system in Wikidata).

For now, I will keep the discussion in the Wikidata mailing list thread, and I will document in the description of this task the progress.

@Wittylama, I'm very excited to read your comment! Very encouraging, and it just came moments after announcing this initiative. Thank you very much.

We are already doing more than imagining GLAM applied to Wikidata, we are applying GLAM datasets to Wikidata at Wikidata:WikiProject sum of all paintings
https://www.wikidata.org/wiki/Wikidata:WikiProject_sum_of_all_paintings
We not only have Maarten who is busy adding painting items from the world's greatest collections, we also have collections who are eager to share data with us and "see what happens". The Rijksmuseum has given us their old catalog codes (from before 1976) in order to make matchups to art catalogs possible. They have also shared with us their iconclass codes on all of the artworks for which we have Wikidata items. These have been added in the property "P1256 Depicts iconclass notation".

@Wittylama - This is very exciting to read, Europeana is a perfect fit. It's not always obvious to organizations I've spoken with that these partnerships are a two-way benefit, they feed in and can pull from the projects. I'd love to learn more about the Europeana project, that would inform my conversations with other orgs.

Jane023 - Great to read about Wikidata:WikiProject sum of all paintings - wonderful project!

I'd like to announce our project and ask for assistance with it. Wikimedia Finland is starting a collaborative project to learn Wikidata with several Finnish organizations and the WP community. The starting point is GLAM data, but we have extended the scope. The partners/datasets are the Finnish Broadcasting Company migrating from Freebase to Wikidata, Laji.fi : Updating Finnish species names, Linked Data Finland: Historical place names, the Association of Finnish Local and Regional Authorities: Basic facts about Finnish municipalities, Open science and research, National Gallery artist and artwork database, GIS database of the National Board of Antiquities and the National Library of Finland, Finto service.
We look for lecturers / instructors for our workshops taking place after summer!

The SoaP project augments existing Wikidata items about paintings that already exist, and creates items in a structured way for paintings that exist in the real world, but are not yet on Wikidata. Many paintings have items because some Wikipedia somewhere has an article about the painting, or because it is in one of the metadata runs that Maarten has been doing. As he creates a body of items based on top museums starting with the GLAMs who have already donated to Commons, I have experimented with two artists to include their body of work as documented by art historians. This is effective as a way to measure the way we model painting items on Wikidata, but also as a way of testing the "findability" of items (I have merged many doubles) and discovering collections for Maarten to "datamine". I started with Frans Hals, and applied the same concept to Pieter de Hooch a few months ago. The result for Hooch is a list on Wikipedia (en/fr/nl) built with the assistance of "Listeria" that links directly to Wikipedia painting articles or Wikidata painting items (in that order of preference) here: https://en.wikipedia.org/wiki/List_of_paintings_by_Pieter_de_Hooch

Thanks for the clarification that "Wiki Loves Open Data [:)] should guide organizations through the process of contributing content to Wikidata" (https://phabricator.wikimedia.org/T104701) ... and World University looks forward to learning how this will work. I also recently posted my email of yesterday to you, Quim, and Jane here - http://scott-macleod.blogspot.com/2015/07/impatiens-species-structuring-world.html - in terms of WUaS's ~ 10 main foci/areas, as possible contributions to Wikidata, and establishing a framework to engage with data engineers and open data organizations.

There is a list of open data and data science institutions at Meta:Innovation

Quim and All, Where does this project stand now? How might we best develop it further? Thank you, Scott

There are suggestions at https://meta.wikimedia.org/wiki/Innovation#Partnerships

@Rogol_Domedonfors, do you or someone you know have any contact with any of these organizations? Since all the organizations listed there so far are based in the UK, do you know whether someone at WMUK would be willing to act as common contact with open data orgs, in the lines of what WMFI is doing?

As explained in https://www.wikidata.org/wiki/Wikidata:Wiki_Loves_Open_Data, first we need to look for organizations that are willing to test and learn wth us. We are not ready yet for reaching out to multiple organizations without established contacts.

I may be able to help with some of the UK organisations: email me. I expect to be at the Wikipedia Science Conference in London, 2-3 September, which would be a suitable venue for a discussion.

@I9606, you added to the description

How to visualize a data model that spans multiple entity types within the context of wikidata?

Can you or someone else explain this, please?

@Richard_Pinch, hi! I'm not joining the Wikipedia Science Conference, but if other Wikimedians loving open data go, please do meet.

Now that the very basic documentation is in place, I'm a bit uncertain about the best next steps. I made a call for feedback and testers at the wikidata mailing list.

Apart from the fine tuning of these pages, what we need are more use cases, some organizations willing to go through their first steps to test this framework and identify better their needs. Wikimedia Finland, Wikimedia Belgium, and others have hinted at ongoing initiatives to collaborate with open data organizations. Can we help? Who else?
