Requirement ----------- It should be possible to query the RDFS structure of an RDF graph to find, for example, the parents and instances of a class or the class tree. Discussion ---------- I'm not sure whether this comes down, in the end, to a semantic requirement or just a request for sugar for a particular kind of query; but what my users need (and we have implemented in a really ugly, API munging way) is the ability to ask for all the instances of a class, all the parents of a class, and so on. Being able to do these queries, and being able to do them "easily" (yes, I know, untestable, but still...) is a real requirement for us. The DIG Description Logic Interface ASK language is, more or less, what we'd like to have. See <http://dl-web.man.ac.uk/dig/>. Best, Kendall Clark
