Hello,
I am reading the documentation of WikiData where I learned that new properties
could be suggested for discussion. But this means adding knew properties to
WikiData. However, is it possible to use existing RDF vocabularies
Not directly. At the moment, you would just rely on a convention saying that a
given wikibase property is equivalent to a concept from some other vocabulary.
However, we are in the process of allowing claims on properties however. Once
this is possible, you will be able to connect properties to external
identifiers, much in the way data items about people etc are cross-linked with
external identifiers.
This would allow you to model the equivalence between wikidata properties and
other vicabularied. However, the software itself would not be aware of the
equivalence, so it would not be explicit in the RDF representation of data
items. But it would be easy for an external tool that knows how to interpret
such claims on properties to build an appropriate mapping using owl:sameAs or a
similar mechanism.
