As a Wikidata reuser, I want to have a canonical URI for EntitySchemas in order to identify them as concepts and access them in various formats e.g. RDF.
Problem:
Although a URI scheme for EntitySchemas is being created in T225778, for it to be useful we will need to add the EntitySchema URIs in the RDF output of Items, Properties and Lexemes where EntitySchemas are addressed in the statements.
Before this is merged we will need to send an Item with a statement linking to an EntitySchema in .ttl format to @dcausse at WMF that can then be loaded into the Wikidata Query Service to see if it all is fine. (P49105)
BDD
GIVEN an EntitySchema
AND an RDF export for a Wikibase entity (Item, Lexeme etc.)
WHEN the value of a statement is an EntitySchema
THEN the EntitySchema ID in the RDF output is prefixed by wd:
Acceptance criteria:
- A .ttl file has been sent to the WMF and has been confirmed that it doesn't break the Query Service
- The EntitySchema ID in the RDF output is prefixed by wd: when the value of a statement is an EntitySchema
