Associating with Wikidata

P4, exact match, can be used to link items on this wiki as follows:

• Q1 (Wikidata) → http://www.wikidata.org/entity/Q2013
• P4 (exact match) → http://www.wikidata.org/entity/P2888

Note:

• HTTP, not HTTPS
• The "www" is required

You can also use this method to link entities to other Wikibases, as you can see on the "exact match" property page.
