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.
