DBpedia, which frequently crawls and analyses over 120 Wikipedia language editions, has ample information about
# which facts are in infoboxes across all Wikipedias
# where Wikidata is already used in those infoboxes
# potential conflicts across Wikipedia language versions
[[metawiki:Grants:Project/DBpedia/GlobalFactSyncRE|GlobalFactSyncRE]] will extract infobox facts and their references to produce a tool for Wikipedia editors that detects and displays differences across infobox facts in an intelligent way to help synchronization and maintenance of infoboxes between Wikipedia versions and/or Wikidata.
