dc:identifier has recently occurred to me here also.

What if we go ahead with the deprecation of skos:externalID, and replace with 
dc:identifier?  (And drop the proposal for a new property skos:localID).

The problem of how to cope with concepts that may have more than one identifier 
(possibly deriving from different schemes) still remains, however.

What if we recommend here that a sub-property of dc:identifier is created by the 
scheme owners for each identifier?  So e.g.

<skos:Concept rdf:about="http://example.org/topics/098">

Where ex:conceptNumber and ex2:id are both hypothetical properties created by 
scheme owners, and both are declared to be subPropertyOf dc:identifier by scheme 
owners.  (Scheme owners can also declare these props as inversefunctional if 
they choose).
