Wikidata:Status updates/2015 06 20

This is the Wikidata summary of the week before 2015-06-20.

Discussions

• German language Wikipedia closed its RfC on usage of Wikidata data. As a result Wikidata data can be used on the project as long as it happens through a template and it has a non-Wikimedia reference.

Events/Press/Blogs

• Past: Office hour on IRC. We talked about cool things that happened around Wikidata over the past 3 months got an update on upcoming developments and Freebase and more. You can read the log.

Other Noteworthy Stuff

• en:South Pole Telescope is a nice example of an infobox completely filled from Wikidata.
• Q20150617 was created on 2015-06-17
• More data from Freebase have been added the Primary Sources Tool. There is also a page to help the mapping of Freebase properties.
• Nice new manual for MixnMatch
• The new nature.com/ontologies links to external ontologies and datasets; among them Wikidata.
• National Gallery of Art and the J. Paul Getty Museum now have entries for all their paintings on Wikidata thanks to wiki project Sum of all Paintings

Did you know?

• Newest properties: takeoff and landing capability, Discogs label ID, Discogs master ID, Discogs artist ID, Encyclopaedia Metallum band id, investor, second surname in Spanish name, CulturaItalia ID, BerlPap identifier, Mapillary id, National Library of Ireland authority
• Newest WikiProjects: Cross Items Interwikis

Development

• Made a small API breaking change to wbeditentity and wbgetclaims modules. Details can be seen in the commit message of https://gerrit.wikimedia.org/r/#/c/217885/
• Worked more on unit support
• Fixed an issue where you'd sometimes select the wrong value when entering a statement unintentionally (phabricator:T98471)
• Switched the whole code base to make use of DataModel 3.0
• The concept of “claims” no longer exists in Wikibase, as all places in the software work with statements. We are making this more and more explicit in the code.
• The autoloading mechanism of the extension changed, see phabricator:T100813
• More work on getting the Wikibase Quality extensions ready for deployment. They'll improve constraint checking and provide checks against 3rd party databases.
• Special:UnconnectedPages had to be reworked (thanks Amir!) because of huge performance issues. Because of this it loses some functionality (being able to specify where the list starts and limiting the list to pages that have local interwiki links). We're working on bringing functionality back without the performance penalty.
• Bene* created a SPARQL abstraction layer for PHP called Asparagus: https://github.com/Benestar/asparagus
• Enabled arbitrary access on arwiki, cawiki, eswiki, huwiki, kowiki, rowiki, ukwiki, viwiki, and usage tracking on dewiki, ruwiki, cswiki and all s3 wikis. (ruwiki and cswiki get arbitrary access on June 23)
• Finishing work on improved handling “invalid” values and statements with deleted properties.
• Small breaking DOM change: Wikibase no longer adds its own <h­1> but uses MediaWiki's default .firstHeading element. (phabricator:T93534)
