Hello all, This is an update regarding the dates of test environment and migration of wb_terms table replacement solution <https://lists.wikimedia.org/pipermail/wikidata/2019-April/012987.html>.
Due to various complications that the developers in the Wikidata team have been working on solving over the last few weeks, we unfortunately will have to push the dates for when a test environment for tools builders will be ready, which was supposed to be ready today, and the following dates for starting migration of wb_terms data into the new schema in production. The new dates are: - 29th of May: Test environment for tool builders will be ready - 12th of June: Property Terms migration starts - 19th of June: Read property terms from new schema on Wikidata - 26th of June: Item terms migration begins - 3rd of July: Read item terms from one of the two schemas (as explained in this task <https://phabricator.wikimedia.org/T221765>) You can find more information regarding those dates and how to prepare for them in this task <https://phabricator.wikimedia.org/T221765>, and we have dedicated a board <https://phabricator.wikimedia.org/project/view/4014> to receive and help with any questions from tool builders that need to update their tools accordingly. In order to keep all discussions in one place, we kindly ask you to react or ask your questions on Phabricator <https://phabricator.wikimedia.org/T221764>. As a reminder, if you want to discuss with the developers, ask questions and get help in order to update your tools, you can join the IRC Mediawiki meeting, today at 15:00 UTC on #wikimedia-tech. Thanks, Léa On Wed, 24 Apr 2019 at 16:30, Léa Lacroix <lea.lacr...@wikimedia.de> wrote: > 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.
