Other Noteworthy Stuff

• The prefix [[lexemes:]] allows to link to a search for lexemes on any Wikimedia wiki. Sample: lexemes:describe (project chat announcement).
• The wikidata-lang JS module got a major update, and now makes accessible pre-generated mappings between Wikidata ids, Wikimedia language code (P424), ISO 639-1 code (P218), ISO 639-2 code (P219), ISO 639-3 code (P220), and ISO 639-6 code (P221), that can also be used by non-JS programs by fetching the desired JSON. Examples:
  • mapping of Wikimedia language codes to Wikidata ids
  • mapping of ISO 639-2 to Wikimedia language codes
• Wikidata-related projects that have been developed/improved during the Wikimedia Hackathon 2021:
  • User:Lucas_Werkmeister/Ranker - Finished and announced the batch modes for the Ranker tool, allowing users to edit the ranks of statements in Wikidata or Structured Data on Commons in bulk
  • Wikidata Lexeme Forms: Portuguese modal adverb - Deployed support for Portuguese modal adverbs in the Wikidata Lexeme Forms tool
  • User:Jon Harald Søby/addSenseImage.js - User script to add images to sense statements on lexemes
  • Wikidata:Tools/Enhance user interface#identifierInput.js - fixing a bug in IdentifierInput.js gadget for Wikidata to better handle when a property has no format restraints
