Announcing the Wikidata Stable Interface Policy
by Daniel Kinzler 23 Aug '16

23 Aug '16

Hello all! After a brief period for final comments (thanks everyone for your input!), the Stable Interface Policy is now official. You can read it here: <https://www.wikidata.org/wiki/Wikidata:Stable_Interface_Policy> This policy is intended to give authors of software that accesses Wikidata a guide to what interfaces and formats they can rely on, and which things can change without warning. The policy is a statement of intent given by us, the Wikidata development team, regarding the software running on the site. It does not apply to any content maintained by the Wikidata community. -- Daniel Kinzler Senior Software Developer Wikimedia Deutschland Gesellschaft zur Förderung Freien Wissens e.V.

Policy on Interface Stability: final feedback wanted
by Daniel Kinzler 16 Aug '16

16 Aug '16

Hello all, repeated discussions about what constitutes a breaking change has prompted us, the Wikidata development team, to draft a policy on interface stability. The policy is intended to clearly define what kind of change will be announced when and where. A draft of the policy can be found at <https://www.wikidata.org/wiki/Wikidata:Stable_Interface_Policy> Please comment on the talk page. Note that this policy is not about the content of the Wikidata site, it's a commitment by the development team regarding the behavior of the software running on wikidata.org. It is intended as a reference for bot authors, data consumers, and other users of our APIs. We plan to announce this as the development team's official policy on Monday, August 22. -- Daniel Kinzler Senior Software Developer Wikimedia Deutschland Gesellschaft zur Förderung Freien Wissens e.V.

Wikidata Toolkit 0.7.0 released
by Markus Kroetzsch 05 Aug '16

05 Aug '16

Dear all, I hereby announce the release of Wikidata Toolkit 0.7.0 [1], the Java library for programming with Wikidata and Wikibase. This is a maintenance release that implements several fixes to ensure that WDTK can be used with recent Wikidata API outputs and future Wikidata JSON dumps. The new version also ships the code used to generate the basic statistics used in the back of the SQID Wikidata Browser [2]. Maven users can get the library directly from Maven Central (see [1]); this is the preferred method of installation. There is also an all-in-one JAR at github [3] and of course the sources [4] and updated JavaDocs [5]. As usual, feedback is welcome. Developers are also invited to contribute via github. Cheers, Markus [1] https://www.mediawiki.org/wiki/Wikidata_Toolkit [2] https://tools.wmflabs.org/sqid/ [3] https://github.com/Wikidata/Wikidata-Toolkit/releases [4] https://github.com/Wikidata/Wikidata-Toolkit/ [5] http://wikidata.github.io/Wikidata-Toolkit/ -- Prof. Dr. Markus Kroetzsch Knowledge-Based Systems Group Faculty of Computer Science TU Dresden +49 351 463 38486 https://iccl.inf.tu-dresden.de/web/KBS/en

Hi, I'm trying to find Wikidata items based on label as follows: > SELECT ?item ?itemLabel WHERE > { > ?item rdfs:label ?itemLabel > FILTER(CONTAINS(LCASE(?itemLabel),"*keyword*")). > } > limit 3 However, for some cases, the following error returns n some cases Query deadline is expired. I mean it works well for some words but fails with others. Could anyone help please? -- Regards, Abdulfattah Safa Senior Software Engineer Mobile: (+972)(599)231600 Skype: fattah.safa *P **Please consider the environment before printing this email*
