Hi Ron, Sue, > Frequently in multilingual thesauri, we want to capture a relationship > of equivalence between different tokens used as altLabels in different > languages. This feature is frequently used in multilingual thesauri such > as the OECD Macrothesaurus, the ILO Thesaurus or Agrivoc (there are > undoubtedly others, but these are the ones that I know about). In Could you give some concrete examples from these thesauri? > I'm hoping that some of the proposals being put forward for > accommodating notes on altLabel tokens will also be able to accommodate > this multilingual requirement. Sue also refers to a future terminological extension of SKOS. I think it might be possible to make the SKOS Core a little bit more complex (by introducing a class Label or Token as range for alt/prefLabel) that allows extension, while in the current design (literals as range for alt/prefLabel) this would be much more difficult to accomodate. Regards, Mark. P.S. sorry for my sloppy wording by using "term"; so deep into this community-of-practice that I thought it was the right word to use. > Ron > [1] Sorry if this use of the word concept offends but I don't know what > other word to use here. > > At 12:29 1/11/2005, Mark van Assem wrote: > >> Hi Alistair, >> >> I'm leaving the "use cases" that I wrote about for later, in this post >> I to summarize what I think Sue Ellen Wright, Bernard Vatant, Phil >> Carlisle and Stella Dextre Clark have been saying (please correct me >> if I'm wrong!)
