"Wikidata is a free knowledge base that can be read and edited by humans and machines alike."

Or in other words, dbpedia done right. It also uses sensible opaque identifiers, rather than relying on abusing Wikipedia article titles.

Please can you add support for linking entities to Wikidata.

For example:

• U2: http://wikidata.org/wiki/Q396 => a3cb23fc-acd3-4ce0-8f36-1e5aa6a18432
• Arcade Fire: http://wikidata.org/wiki/Q58608 => 52074ba6-e495-4ef3-9bb4-0703888a9f68

Open questions:

• Should this replace Wikipedia links (and then infer various Wikipedia language pages automatically using the API?)
