Tool of the week

   - User:Jon Harald Søby/compact items.css
   <https://www.wikidata.org/wiki/User:Jon_Harald_S%C3%B8by/compact_items.css>
   is a stylesheet that shrinks the vertical space items take up on your
   screen, reducing the need to scroll to get an overview of an item. (

   )

Other Noteworthy Stuff

   - The prefix [[lexemes:]] allows to link to a search for lexemes on any
   Wikimedia wiki. Sample: lexemes:describe
   <https://www.wikidata.org/w/index.php?search=describe&ns146=1> (project
   chat announcement
   
<https://www.wikidata.org/wiki/Wikidata:Project_chat#lexemes:_links_to_lexemes>
   ).
   - The wikidata-lang <https://github.com/inventaire/wikidata-lang> JS
   module got a major update, and now makes accessible pre-generated
   mappings
   <https://github.com/inventaire/wikidata-lang/tree/master/mappings>
   between Wikidata ids, Wikimedia language code (P424)
   <https://www.wikidata.org/wiki/Property:P424>, ISO 639-1 code (P218)
   <https://www.wikidata.org/wiki/Property:P218>, ISO 639-2 code (P219)
   <https://www.wikidata.org/wiki/Property:P219>, ISO 639-3 code (P220)
   <https://www.wikidata.org/wiki/Property:P220>, and ISO 639-6 code (P221)
   <https://www.wikidata.org/wiki/Property:P221>, that can also be used by
   non-JS programs by fetching the desired JSON. Examples:
      - mapping of Wikimedia language codes to Wikidata ids
      
<https://raw.githubusercontent.com/inventaire/wikidata-lang/master/mappings/wd_id_by_wm_code.json>
      - mapping of ISO 639-2 to Wikimedia language codes
      
<https://raw.githubusercontent.com/inventaire/wikidata-lang/master/mappings/wm_code_by_iso_639_2_code.json>

Development

   - Designing and planning for the first version of a tool to compare
   Wikidata's data against other databases and find mismatches that might need
   fixing
   - Looking into unit conversion for the Commons Query Service (
   phab:T281468 <https://phabricator.wikimedia.org/T281468>)
   - Improving RDF export performance problems for very large Items (
   phab:T281272 <https://phabricator.wikimedia.org/T281272>)
   - Fixed entity suggestions not showing all Items defined in that
   Property's constraint (phab:T280650
   <https://phabricator.wikimedia.org/T280650>)
   - Removed edit buttons that had reappeared on old revisions of Items
   where they shouldn't be (phab:T281587
   <https://phabricator.wikimedia.org/T281587>)
