Hi François-Paul

There is a consensus to use foaf:focus for this, at least major users of
SKOS (hereafter OCLC) use it

See e.g., the VIAF identifier for Michelle Obama
http://viaf.org/viaf/81404344/
In http://viaf.org/viaf/81404344/rdf.xml there is one concept defined for
each VIAF concept source (concept scheme),
e.g., for BNF :

<skos:Concept rdf:about="http://viaf.org/viaf/sourceID/BNF%7C15968083#skos:Concept"><skos:inScheme
rdf:resource="http://viaf.org/authorityScheme/BNF"/><skos:prefLabel>Obama,
Michelle, 1964-</skos:prefLabel><foaf:focus
rdf:resource="http://viaf.org/viaf/81404344"/></skos:Concept>

As for distinction between the concept and the page about it, seems to me
the general consensus is to consider a skos:Concept as a non-information
resource, so it should have a URI distinct from the one of the page
representing it.

Best

Bernard
