Hello everyone, This is a post about RDF and SKOS in general and only slightly about Stanbol, so there may be more appropriate venues to pose these questions (please let me know). But I thought I'd tap in to the collective brainpower on this list anyway.
I am struggling with the design of my thesaurus. I have a cancer related SKOS thesaurus full of concepts decorated with standard broader, narrower and related terms. What I would like to do is add some other semantic relations between these concepts (such as concept A (remedy) is a treatment for concept B (disease)). I have tried to add my own namespace with these relations , but haven't been able to do this (see below), so I'm guessing this might not be the way to go. I have also learned that skos has a thing called skos:semanticRelation, but I don't really get what such a generic class would achieve without a lot of redundant rdf:id (I think) attributes. So what would be the best way to go about this? I would be most grateful if you could set me on the right path, or let me know where I can get this kind of help. Thanks, Michel PS: To illustrate what I tried, here is a simplified snippet of my inputfile. --------------- <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; xmlns:skos="http://www.w3.org/2004/02/skos/core#"; xmlns:tzw="http://www.tzw.nl/schema#"; > <skos:Concept rdf:about="http://www.kanker.nl/rdf#alvleesklierkanker";> <skos:prefLabel>Alvleesklierkanker</skos:prefLabel> <tzw:treatment rdf:resource="http://www.kanker.nl/rdf#bestraling"; /> </skos:Concept> <skos:Concept rdf:about="http://www.kanker.nl/rdf#bestraling";> <skos:prefLabel>Bestraling</skos:prefLabel> <tzw:indication rdf:resource="http://www.kanker.nl/rdf#alvleesklierkanker"; /> </skos:Concept> </rdf:RDF> ---------- I added the following to my mappings.txt and the indexing goes OK, but I am never able to query tzw:treatment (namespace tzw is not defined!). http://www.kanker.nl/rdf#* tzw:* I have also tried various mappings (tzw:treatment > skos:related or even > skos:treatment) with various success, but I never seem to really get it right. My understanding is there is a fixed set of hardcoded namespaces that Stanbol relies on? Or is there an easy way to add one?
