Oops sorry all I actually forgot to transfer it to the SWD list. -------- Message d'origine-------- De: public-esw-thes-request@w3.org de la part de Antoine Isaac Date: mar. 17/06/2008 11:58 À: Bernard Vatant; Thomas Bandholtz Cc: SKOS; Jérôme Mainka; Thomas Francart Objet : [SKOS] transfering formal comments to SWD group (was RE : When did SKOS namespace change, and why?) Hi Bernard (and others) By the way if you have formal comments (or insults ;-) do not forget that as stated in the reference > All comments are welcome and may be sent to public-swd-wg@w3.org; please include the text "SKOS comment" in the subject line. Once again, I transfer it to the SWD list myself, but I think you should re-write yourself the mail below to make it more 'serious' (it's not the content, but the fact that I'm transfering an ongoing discussion without any edition).

Let me explain my use case and concern. We've been using SKOS in Mondeca for quite a while, among other things, for outcoming workflow towards search engines (Antidot, in cc). This is not for toys, it's implemented in production workflow with major customers. See e.g., http://itis1.antisearch.net/fpnrportal/. You won't see it, but there is SKOS under the hood of the faceted classification. And also we've been importing vocabularies published in SKOS, like GEMET which you know well. Consider we have been as careful as to use only SKOS features we considered stable, and actually they are, (so none of the above), namely we've been using only so far in this workflow. skos:Concept skos:ConceptScheme skos:inScheme skos:hasTopConcept skos:prefLabel skos:broader skos:narrower skos:definition All of those have been there since the early SKOS drafts, even well before it was on the W3C track, and they are still there in the new release, but with a new namespace. Why? The semantics of those has not changed, or has it? > So you shouldn't just change a namespace without considering the need > of further changes in structure, if you want to do so.

Thomas, I don't follow you here. If we don't change anything, we keep using the 2004/ namespace, what happens next? Nothing in our internal workflow, but no compatibility with vocabularies and applications using the new namespace. What I find *very* unwise, to say the least, is that the new draft does not even contains a warning that the namespace has changed! And I can't remember having this discussed on line. Are there any pointers to where/when/why this decision was take? There has been a lot of debate on this list for much more minor points. I will not write down here the various reactions of people involved in the production chain here, first because I'm not used to be rude on line, and second because I'm afraid it would go beyond the average knowledge of french for most people in this forum :-$ . Looking forward to more explanations from SKOS editors.
