Maybe my quest wasn't quite clear. What I need is not any kind of identifier, but a label. An example: the class 025.43 in the Dewey Decimal Classification has the caption "General classification systems". I want to express "General classification systems" AND "025.43" as human-readable labels. Something like [ns declarations omitted] ddc:025.43 rdfs:type skos:Concept ; skos:prefLabel "General classification systems"@en ; skos:notation "025.43" . Of course the notation is implicit from the identifier, but don't we need something explicit, too, even if it's in a way redundant? Lars -- Dr. Lars G.
