Wikidata:WikiProject Freebase/Mapping - Wikidata

The goal of this page is to build a mapping from Freebase properties to Wikidata ones in order to feed the Primary Sources tool.

To map a Freebase property to a Wikidata property, one just appends it with the property number using the P template. If the property can not be mapped to an existing Wikidata property and is the reverse of another one that is already mapped to Wikidata or is not really relevant to Wikidata, just remove it. If you think the property is relevant to be added to Wikidata, you could create a property proposal and add a link to it.

Example:

* https://www.freebase.com/people/person/date_of_birth {{p|569}}

That gives:

• https://www.freebase.com/people/person/date_of_birth date of birth (P569)

The main discussion page for this project is: Wikidata talk:WikiProject Freebase.

Mapping of the 1000 most used properties.

Freebase Schemastaging was an area for work-in-progress schema that had not been officially promoted to /commons. The schema here was influx and under constant revision by Google and the Experts community until it was promoted to /commons. Recommended not to import, but perhaps to use as a basis for creating New properties that Wikidata might like to have.
