Re: wher is the Schema.org context?

Hi Robert,

I see from subsequent mail that you figured out the conneg that lets you get the
JSON-LD context for Schema.org.
Important to note this is *just* the context document, not a representation of
the entire vocabulary.

Here's a link to an example I made for another vocabulary:

It doesn't, it only knows how to use the JSON-LD context to map the value for
"@type" key to a URI. If you then 'follow your nose' and dereference
http://schema.org/Person then you get a representation of that thing that tells
you that schema:Person has type rdfs:Class [1]. If that thing does not exists
e.g. http://schema.org/Foo then you get a 404 response.
