In particular we had Wikipedia in mind.
In the RDF mapping of Wikidata, we currently use schema:about for this relationship. E.g. on <https://www.wikidata.org/entity/Q42.ttl> you will find: <http://de.wikipedia.org/wiki/Douglas_Adams> a schema:Article ; schema:about entity:Q42 ; schema:inLanguage "de" . Note that we say that the Wikipedia page is about the *concept* with the URI <https://www.wikidata.org/entity/Q42>, not about the *page* with the URI <https://www.wikidata.org/wiki/Q42>. As mentioned, foaf:primaryTopic/foaf:isPrimaryTopicOf can also be used to describe such a relationship between an article and a concept/topic. I'm tempted to add that the the RDF mapping, actually... Anyway: wikidata already defines the schema:about relationship for this. So I suggest to use <link rel="schema:about" href="https://www.wikidata.org/wiki/Q42";> in the HTML header on Wikipedia. The Wikibase client extension could actually just do that. -- daniel -- Daniel Kinzler Senior Software Developer Wikimedia Deutschland Gesellschaft zur Förderung Freien Wissens e.V. _______________________________________________ Wikidata-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikidata-l
