It can all be done now - grab a triplestore.

The SKOS vocab can support synsets in various ways, directly like this:

  <skos:Concept rdf:about="http://www.example.com/concepts#folksonomy">
    <skos:prefLabel>folksonomy</skos:prefLabel>
    <skos:altLabel>folksonomies</skos:altLabel>
    <skos:altLabel>taggishness</skos:altLabel>
...

You can express mapping relationships between different (human)
vocabs/concept schemes in quite a few different ways (depending mostly
I guess on what you want to do with the stuff): using SKOS's
broader/narrower, RDF's subClassOf (and owl:equivalentClass) or
owl:sameAs.

Cheers,
Danny.
