• Development
  • Wikidata Bridge: Made a number of technical improvements to wrap up the work in the first version.
  • Reference Hunt: Making final technical improvements and are now running the process to find references on the whole of Wikidata (as opposed to the initial small subset for testing). Once that's done we'll release them as a dump.
  • Easier access to data for programmers: Researching and interviewing ways to improve the APIs in preparation for working on them.
  • Query builder: Working on defining the first version and creating mockups based on the feedback we received.
  • Use modern TypeScript syntax (3.2 -> 3.9) ( phab:T253211)
  • More technical documentation for Federated Properties ( phab:T252991) & preparing for the next steps
  • Convert some properties to external identifiers ( phab:T253722)

• Tool of the week
  • Mix'n'match lets you match lists of external identifiers to Wikidata items, or create new items if necessary. Thousands of catalogs already exist, in dozens of different topic areas, and it's easy to import new ones.

• Other Noteworthy Stuff
  • New: Overview of GLAM metadata standards and (if relevant) how they are mapped and crosswalked on Wikimedia projects. Feel free to add more to the list!
  • Wikidata Lexeme Forms can now group forms înto sections, and (on wide screens) distribute sections across two columns!

• Development
  • Collecting a lot of feedback and doing research around how to improve our APIs to start making it easier to access Wikidata's data for programmers
  • Finalized the initial feature list for the query builder and working on designs and prototypes for testing
  • Doing user research on the Merge gadget to prepare for making it part of the proper code-base so that other Wikibase instances also benefit from easier merging
  • Federated Properties: continued working on the first version of Federation that will make it possible to use Wikidata's Properties in another Wikibase installation
  • Start of a new project (Wikibase Decoupling & Extension Registration) in order to clean up our codebase a bit and make it easier to extend with new features in the future
  • More work on the design system to have a set of unified components for Wikidata that will make it easier to develop new features in the future because we don't have to rewrite components that are used in a lot of places
  • Some MediaWiki skin changes meant broken edit links on Wikipedia and co. Fixed now. ( phabricator:T252800)
