An annotationURI is an > identifier isn't it? -- it is a property name (in fact an annotation > property name). Hm, yes, maybe I was a bit cryptic. What I meant is that every element has a URI-attribute that denotes its identity. Only for annotations the URI is not the identity of the annotation itself, but the identity of the annotation property. >> It would be good to distinguish between the two, as it can get >> really confusing (e.g. when trying to understand annotations). >> Secondly, these names are based on the datatype of the value, and >> not on their intended interpretation (trying to avoid the word >> meaning here...). > > Sorry, but I didn't get this either. Which names did you mean? Ok, this is a bit picking nits, but it is not very elegant to have properties be named after their datatypes. For instance, as 'owlClassURI' denotes an identifier, a better name would be 'owlClassID'. Using 'owlClassURI' as identifier for classes is a bit like using 'personString' as names for persons. -Rinke > > > Ian > > > >> >> -Rinke >> >> ----------------------------------------------- >> Drs.
