Re: How create collections in Skos?

Dear Maya,

1. I'm not so sure about SkosEd; perhaps you can go and create your collection as an individual (in the Individual tab), and then relate it (via skos:member) to the concepts you want in your collections, using the "Object property assertions" feature of Protégé.
But to tell the truth, it wouldn't surprise me too much that Collections are not perfectly supported. SKOS Collections are inherited from the very first version of SKOS, they were never widely adopted. There are quite many proposals to use them around, e.g.,[1,2,3], which adopt slightly different perspectives. None of them is illegal, really, but this does not help interoperability.
So the question would be, do you need skos:Collection, really? Or can you do with simple skos:Concepts instead of them?

2. It is better if concepts come with some context, and concept schemes can be a good way to do this. But you can perfectly create instances of skos:Concept (or instances of a sub-class of skos:Concept) without relating them to a skos:ConceptScheme.

Best,

Antoine
