Basic: Focus more on Linked Data less on RDF

[msporny]

From Kingsley Idehen:

1. Syntactic incompatibility != conceptual incompatibility
2. Microdata, Microformats, RDFa all provide syntax for embedding graphs within HTML documents
3. Linked Data is about using de-referencable URIs in object (resource) description (respresentation) oriented graphs where each URI resolves to a representation of its referent i.e., graph based structured data representation via hyperlinks.

There is no longer a Basic profile for JSON-LD. We have added a section on Linked Data to the spec. This issue has been addressed as much as it can be.
