Hi, I'm not sure about the discovery part - that seems to be more a meta- layer with data describing linked datasets (VoiD [1]). However, I agree that inference would have to be in layer 4 and up. Things like non-explicit object consolidation, vocabulary and ontology mapping, etc. will be necessary to integrate the data even beyond the point of explicit links. @ravinder: I like the three layers you propose - is there a reference for that, or did you come up with it just now? I'd love to reference it in my PhD thesis! Cheers, Knud [1] http://semanticweb.org/wiki/VoiD On 15.12.2008, at 20:54, Juan Sequeda wrote: > Hi Ravinder, > > Interesting points.
