No, indeed: we've just barely got past the point of agreeing that there should be vocabularies/thesauri.
Indeed, this need will be common to all VO contexts, so it would be great to have a standard solution. I once suggested using the rdf:Bag et al. elements, e.g.
<rdf:Bag id="LMSAL:FilamentEruption"> <rdf:li resource="ivoat:solarfilaments"> <rdf:li resource="ivoat:eruptions"> </rdf:Bag>
but I admit that it's not an elegant solution (assuming that our computers care). Our original idea of using a UCD-like may have had many faults, but the ease of concatenation wasn't one of them. Now that the semantics crew is about to suggest SKOS as the IVOA standard, we've almost defined the path but haven't defined the goal.
