Simon-thanks for the suggestions, and sorry I haven't been able to get back
to you on them yet. I hope to get to look at them this weekend, I'm eager to
get 201202 into tags and see the vocab services deployed.

Subject: Some observations on the CGI vocabs


Hi Steve - prompted by the flurry of email today, I've taken a look at a
couple of the vocabs. 

Good work. I'm seeing some basically minor issues that would make them even
better ... 


1.      For each of the vocabularies, you have used the Ontology URI to
identify the ConceptScheme. This is beyond OWL-DL (or OWL2-RL), so is
generally frowned on by DL-nazis. Mind you, these days I'm relatively
unconvinced that ConceptSchemes provide much utility, so I just use a
placeholder URI, like AlterationType:Scheme. 

2.      OTOH I find that a skos:Collection for each partial URI, ending in
"/", helps navigation, as you can use skos:member to point to all the
initial members. 

3.      Not clear why all the concepts are type=owl:NamedIndividual as well
as skos:Concept?  And is it necessary to include the superclass owl:Thing? 


None of these will have much direct effect on the things that matter (the
concepts, the concept hierarchy, labels and definitions) but will make the
vocabularies more digestible to SemWeb types. 


I've processed two examples where I have done the suggested remediations.
