We plan to drop the wb_entity_per_page table
by hoo 01 Jun '17

01 Jun '17

Hey folks, we plan to drop the wb_entity_per_page table sometime soon[0], because it is just not required (as we will likely always have a programmatic mapping from entity id to page title) and it does not supported non -numeric entity ids as it is now. Due to this removing it is a blocker for the commons metadata. Is anybody using that for their tools (on tool labs)? If so, please tell us so that we can give you instructions and a longer grace period to update your scripts. Cheers, Marius [0]: https://phabricator.wikimedia.org/T95685

WDQS examples migrated
by Stas Malyshev 04 Mar '17

04 Mar '17

Hi! I've finished migrating SPARQL examples to https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/queries/examples - this is now the official examples page. I've also created a redirect: https://www.wikidata.org/wiki/Wikidata:SPARQL_examples for convenience. The old page at mediawiki.org is now soft redirect to a new one. Please notify me if you see any issues. Thanks, -- Stas Malyshev smalyshev(a)wikimedia.org

Greater than 400 char limit for Wikidata string data types
by Sebastian Burgstaller 05 Jan '17

05 Jan '17

Hi all, I think this topic might have been discussed many months ago. For certain data types in the chemical compound space (P233, canonical smiles, P2017 isomeric smiles and P234 Inchi key) a higher character limit than 400 would be really helpful (1500 to 2000 chars (I sense that this might cause problems with SPARQL)). Are there any plans on implementing this? In general, for quality assurance, many string property types would profit from a fixed max string length.

Master thesis
by Nazanin Kamali 10 Nov '16

10 Nov '16

Dear all, My name is Nazanin and I am a Wikipedia editor. I studied statistics in my undergraduate program and recently I have begun my master program also in statistics. According to my interests in Wikimedia projects, I would like to choose a Wikidata-related project as my master thesis. I have already worked on descriptive statistics and I look forward to working on Monte Carlo methods for forcasting, simulation and modelling. How can I help in Wikidara and how could we have a productive cooperation? All the best, Nazanin

Stable Interface Policy: Database Schema as a stable API
by Daniel Kinzler 04 Nov '16

04 Nov '16

Hi all! I plan to add the wikibase (SQL) database schema as a stable interface. Typically, a database schema is considered internal, but since we have tools on labs that may rely on the current schema, breaking changes to the schema should be announced as such. To address this, I plan to add the following paragraph to the Stable Public APIs section: The database schema as exposed on Wikimedia Labs is considered a stable interface. Changes to the available tables and fields are subject to the above notification policy. In addition, I plan to add the following paragraph to the Extensibility section: In a tabular data representation, such as a relational database schema, the addition of fields is not considered a breaking change. Any change to the interpretation of a field, as well as the removal of fields, are considered breaking. Changes to existing unique indexes or primary keys are breaking changes; changes to other indexes as well as the addition of new unique indexes are not breaking changes. If you have any thoughts ob objections, please let me know at <https://www.wikidata.org/wiki/Wikidata_talk:Stable_Interface_Policy#Databas…> -- Daniel Kinzler Senior Software Developer Wikimedia Deutschland Gesellschaft zur Förderung Freien Wissens e.V.

Tool to identify the articles versions across Wikipedia language editions?
by Reem Al-Kashif 01 Nov '16

01 Nov '16

Hi, Hope this finds you all well. I'm wondering if there is a way/tool to identify the articles that exist in the one edition of Wikipedia and have counterparts in another. I'm also wondering if there is a way to generate a list of these articles' titles for certain categories. Best, Reem -- *Kind regards,Reem Al-Kashif*

Birthday: Parser function, Scholia, and a new story
by Léa Lacroix 31 Oct '16

31 Oct '16

Hello folks, Today I start by sharing *a blog post <http://stryn.eu/blog/2016/10/4-years-of-wikidata/> from @Stryn <https://www.wikidata.org/wiki/User:Stryn>:* who's involved on Wikidata since the beginning of the project! Thank you Stryn :) We received several birthday presents from editors, that's so great! Maybe you already know about *Scholia <https://tools.wmflabs.org/scholia/>*, a tool to create scholarship profiles built on the Query Service. Its creator fnielsen <https://www.wikidata.org/wiki/User:Fnielsen> added a search field, you can now type the name of a person (or the Qid) to see more about researchers' education, employers and publications. Thanks Finn for your work! Lastly, let me introduce you a improved feature my colleagues are offering you for the birthday: *the parser function {{#statements:…}}*. As you may know, for three years the function {{#property:…}} is deployed on all Wikimedia projects and allows you to display data from Wikidata, without using LUA. For example, the code {{#property:P1559|from=Q42}} will display Douglas Adams. We improved this tool in a new parser function: {{#statements:…}}. The new wikitext format renders statement values as *syntactically meaningful elements* instead of just plain text. For example, entity IDs are clickable links that link to the corresponding article, external identifiers link to the external authority, and Commons media files are rendered as thumbnails. The new output format will be available via a new {{#statements:…}} parser function, via a new “formatStatements” Lua function, and via the “wbformatentity” API, when used with “generate=text/x-wiki”. The new parser function is in early development. The output produce may change any time. {{#statements:…}} is currently disabled on all wikis except the beta cluster. We hope to enable it within the next weeks when we consider the feature stable enough. For now, you can see and test it on the beta German Wikipedia. *See an example and the difference between the two functions <https://de.wikipedia.beta.wmflabs.org/wiki/Statements?uselang=en>*. We are really interested by your feedbacks: please leave comments on the Phabricator ticket <https://phabricator.wikimedia.org/T142940> or on Wikidata:Contact the development team <https://www.wikidata.org/wiki/Wikidata:Contact_the_development_team>. This feature was built by multiple developers from the Wikidata team with help from volunteers. Mostly hoo_man <https://www.wikidata.org/wiki/User:Hoo_man> and Thiemo Mättig (WMDE) <https://www.wikidata.org/wiki/User:Thiemo_M%C3%A4ttig_%28WMDE%29> as well as Daniel Kinzler (WMDE) <https://www.wikidata.org/wiki/User:Daniel_Kinzler_%28WMDE%29> and Jonas Kress (WMDE) <https://www.wikidata.org/wiki/User:Jonas_Kress_%28WMDE%29>. Special thanks to the volunteers that contributed in Phabricator discussions, especially Izno <https://www.wikidata.org/wiki/User:Izno>!
