SKOS-XL (was RE: SKOS/ synonym provenance (ISSUE-27 AnnotationOnLabel))

Hi Jon,

You just reminded me, after the amsterdam f2f I wrote up a specification for an *extension module* for SKOS, which I think captures your requirements:

[2] <http://www.w3.org/2006/07/SWD/wiki/SkosDesign/SKOS-XL>

This takes the many-to-one position [3].

My current feeling is *not* to include anything like this in the main SKOS recommendation -- i.e. to limit the SKOS recommendation to *only* dealing with labels as RDF plain literals, which would keep it smaller and simpler. 

I think it would then be quite reasonable to publish something like SKOS-XL as a separate, stand-alone, extension to SKOS, for advanced users. 

The SWDWG could itself publish such an extension, or anyone from the SKOS community could do so. E.g. the FAO used their own extension to represent something like this.

If the SWDWG left it to the community, to help promote discovery and convergence, the SWDWG could set up a wiki page where members of the community could "register" their SKOS extensions ... or we could even use your metadata registry to do that :)

Finally, note that [1] doesn't have any "story" to it -- it's just bare bones. Even as an extension module, [1] would need a story to go with it. To be even considered for inclusion in SKOS proper, it would need a very good story. I haven't got a story at all the moment, and I haven't heard anyone tell one yet either, so my position as stated in the summary of [3] still holds. Have you got a good story? 

Cheers,

Al.
