Dear Mike: If you critize the proposal for deferring part of the semantic alignment to the consumer, and claim that an approach that allows preserving that much of meta-data as can be easily provided by sites is useless, then you must also claim that RDF is useless. RDF does not bringt more to the table than a portable mechanism for exchanging very lightweight conceptual structures. Still, the whole Web of Data and Linked Open Data Cloud celebration, in essence only uses RDF from the Semantic Web technology stack. So if you say that a proposal that allows preserving a few core data modeling primitives in Web data is not an advancement, you must also say that all enthusiasm over existing work on the Web of Data and the Linked Open Data Cloud is a hollow, useless celebration, for there is not semantic reconcilitation of the underlying data schemas.
