In addition to Reza's questions i would like to ask whether the WG will consider
linked data in XML and JSON in addition to linked data in RDF.
All the best, Ashok

The fact that the concepts, data models, notations, constraints, ontology, query and access are separated, IMHO, is a hallmark of clean standardization work.  It allows implementers to implement part or all of the standard without creating dependencies on vendor-based ecosystems.
