Hi, Some on the Sem Web list will have come across the POWDER working group [1], part of the Semantic Web Activity, and some have been kind enough to comment on our work to date. Thank you. We'll go on providing information through the public mailing list [2] and blog [3] however... we need help with a very specific issue that the WG is having great difficulty resolving. Minimal background: What is a Description Resource? It's a little block of RDF/OWL that contains a set of descriptors that can be applied to a group of resources - typically everything on a given Web site. The entity that publishes the Description Resource (DR) is always identified. The idea being that if you can authenticate that the entity really did describe the Web site that way, and if you trust that entity's judgement, the description is useful. So we have 3 equally important components in a DR: - Attribution (Who is saying this) - Scope (what is being described) - Descriptors. The current public working draft of one of our Rec Track documents includes a generic example of a DR [4]. Each of the three components is clearly delineated as part of the DR. The processing model is set out below the generic example (including some sample SPARQL queries). So here's the issue we can't solve. Should the hasDescriptors property that links to the Descriptors Class be a property of the Description Resource or the Resource Set? Arguments for each are set out in the doc. Any input would be extremely welcome as it's doing our heads in trying to solve this. Thank you. Phil.
