WikiData







Project plan: 3 phases

Phase 1: Language links

Phase 2: Infobox augmentation

Phase 3: Inline queries


Phase 1: Language links

Current: every language links to every other

In Wikidata: create one page for each entity, list representations in each language

In Wikipedias: pull language links from Wikidata


Phase 2: Infobox augmentation

Current: each article calls an infobox with values

In Wikidata: centralize the values

In Wikipedias: just call the infobox and populate it with values from Wikidata


Phase 3: Inline queries

Enable inline queries in WikipediasWith several formats
