Turtle (and N-triples for dumps), RDFa, JSON-LD.  RDF/XML is an optional 

Conneg sorts this out - this WG can provide guidance that Turtle (or NT) 
is always available). (RDF/XML is expensive to produce; nice RDF/XML 
even more so).

But it is not a full metamodel - that runs into the problem of separate 
domains having the same metamodel but no interchange.  metamodels can be 
too abstract.

Interchange is critical to this WG - it's not standards for closed 
systems where shared understanding (developer skills etc) is the only 
shared aspect.

There is "linked data" where all the links are in Link headers, or 
<meta> tags.  That gives document-document links.  RDF gives 
entity-entity links.
