I think that the core concept here is that RDF provides a common model for representation of content at the conceptual or logical level <<as well as>> for the serialized/wire format level, thereby focusing all interoperability issues on semantics rather than technology barriers, semantic transformation impedance as one moves from conceptual to implementation representations, or other serialization "brittleness" such as what occurs with vanilla XML where it is easy to produce two semantically equivalent conceptual/logical representations that serialize differently and are therefore non-interoperable.

Starting with RDF or OWL representations of the HL7 RIM (actually the MIF since you need data types and terminology bindings and there relationships to the RIM as well as the RIM itself) enables the semantic standards expressed in the "idiosyncratic formats" you mention then becomes an instance of RDF representation drawn from an underlying RDF/OWL representation, i.e. we need to base interoperability on the representation of standards in RDF.  The standards-derived artifacts then become focused on semantics rather than other spurious issues.

The first version of the HL7 MIF in OWL is now available for comment, criticism, evolution, and usage.

Agree with this and want to add one more - this statement from the document:
        "Meaningful Use currently mandates a patchwork of idiosyncratic formats, such as HL7, CCD/ C32, CCR, NCPDP SCRIPT, C-CDA and QRDA. While such formats provide a degree of machine processability, in comparison, RDF offers significant advantages:"

        - How can you compare RDF to these models? Surely you can serialize data that conforms to these standards into RDF, no?

thanks
Sivaram
