Jeff and all,
I wonder if you (or any of you) have studied Topic Maps, the ISO/IEC 13250:2003.

"A topic map represents information using
topics, representing any concept, from people, countries, and organizations to software modules, individual files, and events,
associations, representing hypergraph relationships between topics, and
occurrences representing information resources relevant to a particular topic."[1]

Some underlining ideas of yours seems to align with Topic Maps data model.[2]
Just a thought.

Thanks for the feedback. It is altering my thinking about "the aggregate
model". Now I'm "pretty convinced" that
http://viaf.org/ontology/1.1/#Heading should go away in favor of
straight use of skosxl:Label. What was I thinking?

The real issue I'm trying to work around is the
http://www.w3.org/TR/skos-reference/#S14 integrity constraint on
skos/xl:prefLabel, In "the contributor model" this constraint shouldn't
be a problem. In the aggregate model, though, contributed prefLabels
collide and VIAF isn't (currently?) prepared to pick a winner for each
language tag. It would be a shame to dumb them all down to
skosxl:altLabel. In VIAF 1.1, we coined
http://viaf.org/ontology/1.1/#hasEstablishedForm and
http://viaf.org/ontology/1.1/#hasXrefAlternate to sidestep the S14
constraint. How would people feel about us upgrading these properties
like so:

viaf:hasEstablishedForm a owl:ObjectProperty ;
        rdfs:subClassOf skosxl:altLabel ;
        rdfs:domain skos:Concept ;
        rdfs:range skosxl:Label .

viaf:hasXrefAlternate a owl:ObjectProperty ;
        rdfs:subClassOf skosxl:altLabel ;
        rdfs:domain skos:Concept ;
        rdfs:range skosxl:Label .

Contributed skos:Concepts could then be associated with a common set of
skosxl:Labels using skosxl:prefLabel/altLabel. If and when VIAF picks
language tag winners, these properties could be deprecated.
