[Breaking change] Important for Wikidata tools maintainers: wb_terms table to be dropped at the end of May
by Léa Lacroix 05 Jul '19

05 Jul '19

Hello all, This is an important announcement for all the tool builders and maintainers who access Wikidata’s data by *querying directly Labs database replicas*. In May-June 2019, the Wikidata development team will drop the wb_terms table from the database in favor of a new optimized schema. Over years, this table has become too big, causing various issues. This change requires the tools using wb_terms to be updated. Developers and maintainers will need to *adapt their code* to the new schema before the migration starts and switch to the new code when the migration starts. The migration will start on *May 29th*. On May 15th, a test system will be available for you to test your code. The table being used by plenty of external tools, we are setting up a process to make sure that the change can be done together with the developers and maintainers, without causing issues and broken tools. Most of the documentation and updates will take place on Phabricator: - In this Phabricator task <https://phabricator.wikimedia.org/T221764>, you can find a description of the changes and the process, and you can ask for more details or for help in the comments. This is also where updates will be announced if necessary. - On the Tool Builders Migration board <https://phabricator.wikimedia.org/tag/wb_terms_-_tool_builders_migration> you will find all the details about the migration, how to update your tool <https://phabricator.wikimedia.org/T221765>, and you can add your own tasks. - If you need to discuss with the Wikidata developers or get more specific help, we set up two dedicated IRC meetings and a session at the Wikimedia hackathon. More information in this task <https://phabricator.wikimedia.org/T221764>. We are aware that this change will ask you to make some important changes in your code, and we are willing to help you as much as our resources allow us to. We hope that you will understand that this change is made to avoid bigger issues in the near future. Note that this change is not impacting Wikibase instances outside of Wikidata. A dedicated migration plan and announcement will follow. We strongly encourage you to not wait until last minute to make the changes in your code. If you have any question or issue, we will be happy to help. In order to keep the discussions in one place, please ask questions or raise issues directly in the Phabricator task and board. Thanks for your understanding, Cheers, -- Léa Lacroix Project Manager Community Communication for Wikidata Wikimedia Deutschland e.V.

Wikimedia language conference on 4-5 July in Cornwall
by Léa Lacroix 06 Jun '19

06 Jun '19

Hello all, The Celtic Knot Conference <https://meta.wikimedia.org/wiki/Celtic_Knot_Conference_2019>, dedicated to languages in the Wikimedia projects, will take place on 4th and 5th of July in Penryn, Cornwall, UK. The conference aims to bring people together to share their experiences of working on sharing information in minority languages, and to help people learn how to encourage the flow of information across language barriers and support associated communities. During the previous editions <https://wikimedia.org.uk/wiki/Celtic_Knot_Conference_2018#Programme>, a lot of Wikidata-related sessions took place, and the conference especially helped bringing together editors of small Wikipedia communities who wanted to make more use of Wikidata <https://blog.wikimedia.org.uk/2018/08/celtic-knot-2018-how-can-wikidata-sup…>, but lacked resources or technical skills. We hope that this gathering will bring together again plenty of people who are enthusiastic about sharing knowledge across (project) borders and languages! The call for program submissions is now open until May 16th. More information about attendance and possible ways to get funded will certainly follow. I already submitted a Query Booth <https://meta.wikimedia.org/wiki/Celtic_Knot_Conference_2019/Submissions/Que…> - the format where people can exchange knowledge about SPARQL and help each other to build queries has been successfully tested at the WikidataCon and other events. If you plan to join the conference and would like to help at the booth, feel free to register on the page! if you have any question, feel free to reach me or the main organisation contact, Mark Trevethan.

New status of constraint: "suggestion"
by Léa Lacroix 06 May '19

06 May '19

Hello all, As you may know, we currently have two levels of property constraints <https://www.wikidata.org/wiki/Special:MyLanguage/Help:Property_constraints_…>: mandatory constraints and "normal" (non-mandatory) ones. In order to allow more flexibility and subtlety in constraints definition, we are going to introduce *a new constraint level, suggestion*. This way, editors can distinguish the really crucial constraint violations from the ones that only suggest additional edits that would be nice to make. When setting up a constraint rule, you could define it as a suggestion by adding a qualifier to the constraint definition statement with the property constraint status (P2316) <https://www.wikidata.org/wiki/Property:P2316> and the value suggestion constraint (Q62026391) <https://www.wikidata.org/wiki/Q62026391>. The suggestion constraint would get a specific icon to make it clearly different from the mandatory and non-mandatory constraints. The current icons look like this: [image: Screenshot icons for Wikidata constraints.png] <https://commons.wikimedia.org/wiki/File:Screenshot_icons_for_Wikidata_const…> https://commons.wikimedia.org/wiki/File:Screenshot_icons_for_Wikidata_const… The feature will be enabled on May 6th. Starting from this date, you will be able to define constraints as suggestions and they will be displayed as such for all logged-in users. Please note that this is the first roll-out of the feature, some issues may appear. You are also very welcome to give feedback, if some things are not working as you wish they would, we can still fix them. In that case, feel free to ping me or write a comment in the related ticket <https://phabricator.wikimedia.org/T204439>. Thanks to the people who made this request, this feature was suggested during one of the “pink pony session” at Wikimania and we hope that you will enjoy it!

wb_terms redesign
by data_querier 04 May '19

04 May '19

This is really a defective redesign. It reintroduced numeric IDs to be removed by T114902. See also T179928. We should reconsider reintroduce a new table to link unperfixed and perfixed entity ID. Also oppose any "partial migration for first XXX items" process in T221765: this makes queries much more complicated. Please first fill all data in the new schema, then discontinue the old table.

[Breaking change] Empty containers in JSON outputs will be serialized as empty object "{}"
by Léa Lacroix 30 Apr '19

30 Apr '19

Hello all, This change is relevant for everyone *using APIs, JSON output and dumps in their tools or gadgets*. Currently, when an object is empty (for example descriptions and aliases), it is rendered as an empty array [] in JSON. (Example <https://www.wikidata.org/wiki/Special:EntityData/Q24075199.json>) We want to serialized it as an empty object {} instead. This change will ease the deserialization process and bring more consistency in our code as some other places already use JSON objects instead of arrays. The impact of this change will be in JSON outputs (Special:EntityData) and JSON dumps, as well as the output of wbgetentities, wbgetclaims and editing APIs. If you’re maintaining tools that use Special:EntityData, you may want to check your code to make sure that it reflects this change, e.g. items with no labels, descriptions, aliases or sitelinks are properly deserialized by your tool. You can already *test your code* against our test system on beta.wikidata.org, for example on this item <https://wikidata.beta.wmflabs.org/wiki/Special:EntityData/Q521829.json>. According to our stable interface policy <https://www.wikidata.org/wiki/Wikidata:Stable_Interface_Policy>, the change will be enabled four weeks after this announcement, on April 30th. In the meantime, if you have any issue or question, feel free to leave a comment in this ticket <https://phabricator.wikimedia.org/T138104>.

Suggestions based on constraints will be enabled for all users on April 24th
by Léa Lacroix 25 Apr '19

25 Apr '19

Hello all, In March <https://www.wikidata.org/wiki/Wikidata:Project_chat/Archive/2019/03#Suggest…>, we told you that we want to make the beta feature providing suggestions based on constraints to all users. Some of you gave us feedback and pinged us about unresolved issues (thank you for that!). These issues are now solved: - the order of suggestions in the case of a property having a one-of constraint now matches exactly the order of the constraint (phab:T220587 <https://phabricator.wikimedia.org/T220587>) - the results appearing in the drop-down menus are now links: you can open them in another tab (phab:T207363 <https://phabricator.wikimedia.org/T207363>) We're now ready to enable the suggestions based on constraints for all users (including non-logged-in users). It will take place next week, on April 24th. The beta feature will still be available during a few days (in case something goes wrong and the deployment train is rollbacked, for example), but if everything works well and no major issue is reported, we will disable the beta feature one week after the deployment. You can see more information about the feature on the documentation page <https://www.wikidata.org/wiki/Help:Property_constraints_portal/Entity_sugge…>. Please note that the feature is not preventing users to add any item they want as a value, you can still type in and choose the item you want, but it is making more useful suggestions, based on criteria defined by the community with the constraints, and hopefully reducing the number of mistakes and improving the user experience when adding new statements. If you have any question or issue, feel free to write me. Cheers, -- Léa Lacroix Project Manager Community Communication for Wikidata Wikimedia Deutschland e.V.
