Antoine, 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.
