Hi Leonard, No, this is something a bit different. Others will be able to explain the intention more clearly than I, but here's a brief go (I hope I don't do more harm than good) ... The principle motivation is to provide a bridge between two *styles* of describing things, which collide on the semantic web. The 'ontology style' describes things in terms of their properties (i.e. with *logical* constructs). For example, you can use OWL (and FOAF) to talk about 'the Person with email address <mailto:a.j.miles@rl.ac.uk>'. The 'thesaurus style' describes concepts by using their indicative lexical labels, explanatory prose, and links to semantically related concepts (i.e. with *linguistic* constructs). For example, you can use SKOS Core to talk about 'what I have in mind when I use the term [Alistair Miles]'. The proposal here is to model 'the Person with email address <mailto:a.j.miles@rl.ac.uk>' and 'what I have in mind when I use the term [Alistair Miles]' in RDF as *separate resources*. A special predicate (i.e. skos:denotes or whatever) may then be used to link them. It would be nice to have a firm philosophical basis for this proposal, but I think the primary motivation is pragmatic (i.e. how to cope in practise with co-existence of OWL and SKOS Core) so ... hmmm. That's it for now.
