RE: Brainstorming: Key Issues

It might help if "surrogate" was included on the library terminology page: http://www.w3.org/2001/sw/wiki/Library_terminology_informally_explained. 

I think it's safe to say that a "surrogate" is never "the real thing". The term "surrogate" doesn't exist in any RDF vocabulary, but skos:Concept does exist and can serve the same purpose. As long as the labels (aka headings) are intuitive, neither of these models of abstraction require everyone to agree on the modeling of reality. Nevertheless, foaf:focus provides us with an RDF property to attempt the feat:

ex:1 a skos:Concept ;
 skos:inScheme ex:myScheme ;
 skos:prefLabel "Aristotle"@en ;
	skos:prefLabel "Ἀριστοτέλης"@grk ;
	foaf:focus ex:2 .

ex:2 a foaf:FeatherlessBiped ;
 foaf:name "Aristotle"@en ;
 foaf:name "Ἀριστοτέλης"@grk .
