I think that the symbols are effectively preferredTerms in a particular person's vocabulary - it's just that they use what we think of as pictures instead of the glyphs that represent "normal" fonts. So the question is more the range of the "term" properties and whether they are fixed sa text or can be resources. It might be interesting to make a subproperty of preferredLabel and altLabel that is also a subProperty of foaf:depicts, and suggest the use of that specifically for symbols, but it might be overkill - it still depends on having an appropriate range to start with. I certainly think it is more important that the symbols are represented as first class terms in SKOS than that they are linked to other vocaublaries such as FOAF, although I think that is a vry positive step. (Providing ways of linking to Dublin Core subject vocabularies is more along the lines of using foaf:depicts - very helpful but not the core problem). There are similar possibilities in VoiceXML, where there are a handful of options available in an interaction designed to be through voice, and developers will define assorted ways of recogninsing from a user's speech which of the relevant concepts is being matched. (It is not real natural language processing, but more pattern matching in situtations which are tightly enough constrained that it looks like it...) This all gets further complicated by the fact that Unicode are in the process of encoding a set of these symbols (Bliss) which effectively means encoding a number of these concepts as single characters which we expect to have available in general... cheers Chaals On Tue, 24 Feb 2004, Miles, AJ (Alistair) wrote: > >*Chaals: >One thing that struck me is that I am not sure if we have set up for the >idea that a preferred term for a concept, in a particular vocabulary, might >be represented by an image or multimedia object rather than a text term... > >I had thought about using the foaf:depiction property to allow an image >representation of a concept.
