Project plan: 3 phases
Phase 1: Language links
Phase 2: Infobox augmentation
Phase 3: Inline queries
Denny Vrandečić58 07.02.2012 Wikidata
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
Denny Vrandečić59 07.02.2012 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
Denny Vrandečić60 07.02.2012 Wikidata
Phase 3: Inline queries
Enable inline queries in WikipediasWith several formats
