Hi Dan
I bit my tongue in my previous message not to re-open this issue, but
since you opened it ...

Again, +1.

I really like that idea.
But was puzzled by this "malign syntax", and tried to figure how tools
support that.
Added it to my test ontology, and imported it in my favourite ontology
editors to see how this syntax flies
In Swoop 2.3, the "implicit blank node" was just ignored. :-(
In Protégé 3.2, got as value of skos:as this string
'SimpleInstance(nullA0 of [Cls(protege:ExternalResource, FrameID(0:9106
0))])'. Cool :-D
Just to make sure, tried a less simplified syntax, with an explicit
blank node class
<owl:Class rdf:ID="Person">
<skos:as>
<skos:Concept skos:prefLabel="Person" skos:altLabel="Guy"/>
</skos:as>
</owl:Class>
Seems a bit better digested by Swoop, at least in the GUI, but after
saving re-exports this
<owl:Class rdf:about="#Person">
<skos:as rdf:resource="#genid1"/>
</owl:Class>
Looking for the #genid1 definition ... hmm, it's not in the file.
But I find a poor lonesome concept
<skos:Concept skos:altLabel="Guy" skos:prefLabel="Person"/>
Did not even try in Protégé. Actually OWL editors are not happy with
blank nodes which are not built-in OWL constructs (complex classes such
as unionOf ...)
So ... maybe DL compatible, but not OWL-editors-of-the-market-friendly
Devil is in the details ...
