Re: JSON-LD for emerging healthcare standard (FHIR)?

The context of this work is that the vast majority of the people using 
it will not be using RDF, they will process it simply as JSON.  Thus, 
the requirement to be conveniently processable as JSON is a *much* 
higher priority than the requirement that it also be interpretable as 
RDF.  The idea of using JSON-LD is to enable the JSON format to be 
interpretable as RDF without having to define a third representation 
(beyond XML and JSON) or a separate mapping to RDF.

We RDF folks are guests at this particular banquet -- not hosts.
