Hello! No, I don't know. What you could do is to use a regular linked data property like owl:sameAs with as value the URI of the Wikidata item, like http://www.wikidata.org/entity/Q1391034. So you would have something like (using wd: as prefix for http://www.wikidata.org/entity/):
mydata:writer/561 a efrbroo:F10_Person ; owl:sameAs wd:Q1391034 .
Yes, the preferred way to refer to Wikidata items in RDF is definitely to use their URI, not just their string ID. Whether owl:sameAs is the right property for your case depends on what you use your data for. One could also use weaker notions that provide the link without asserting identity.
An important advantage of using URIs instead of string IDs is that you do not need to encode that this is a Wikidata ID. You can use any property you like to make the connection, and it will still be clear from the URI that you refer to Wikidata.

Hello,
I stored in a database about writers in breton language the wikidata item ID associated to those writers (for instance, Q1391034 for Théodore Hersart de La Villemarqué). Is there a property in a RDF ontology to designate a Wikidata item ID (or should I say entity ID ?) ? So that I could expose my data in RDF with triplets like:
mydata:writer/561 a efrbroo:F10_Person ; wd:????? Q1391034.
Thanks,
