Re: Using iso-thes to publish 1:n-relations between skos:Concepts from different concept schemes

Hello Lars,

Sorry for the delay answering this email.

You are right in your understanding of ISO-THES' CompoundEquivalence is rather between terms/labels and concepts.

MADS/RDF may have something better, with madsrdf:ComplexType and madsrdf:componentList
http://www.loc.gov/standards/mads/rdf/

But perhaps the closest thing available is the XKOS pattern for correspondences:
http://www.ddialliance.org/Specification/XKOS/1.0/OWL/xkos.html#correspondences

(in fact I've delayed this mail because I wanted to review XKOS)

I'm not sure it does all you need, though. XKOS doesn't have 'typed correspondences' of the form of 'OR' and 'AND' combinations, which were identified as a requirement in the SKOS context.
The names they use are also not so great. See
https://github.com/linked-statistics/xkos/issues/31

Best,

Antoine

We don't publish those relations yet since we haven't found a best practice. I've been looking at madsrdf which sort-of-works and last week I delved into iso-thes which has CompoundEquivalence which looks like a good starting point. However, if I understand the documentation correctly CompoundEquivalence can only be used between _terms_ (within one KOS?) and not between _skos:Concepts_.
