Is there a mapping from media type (e.g. application/json) to RDF
literal datatype? In this use case, the data is specifically JSON
embedded in a literal rather than an RDF graph representable as
JSON-LD, e.g.
  :id :prop "{ \"a\": [1, 2, 3]}"^^rdtype:json
where rdtype is some spec which maps
  application/json => "json"
  text/csv => "csv"

Maybe the right thing to do is say that everything in column 1 of
http://www.iana.org/assignments/media-types/media-types.xhtml#application
is an rdtype local name. That would render ambiguous the backward
mapping for media types in e.g. both an app/ and a text/ trees, but
I don't know that there's much use in knowing whether anything in
this list is app/ vs. text/:

      1d-interleaved-parityfec
      activemessage
      dns
      ecmascript
      encaprtp
      example
      javascript
      parityfec
      raptorfec
      rtf
      rtploopback
      rtx
      ulpfec
      vnd.curl
      xml-external-parsed-entity

If there is a usefull difference, we could have different prefixes for
the different trees: application, audio, example, image, message,
model, multipart, text, video, and prefix declarations can call them
e.g. "rdapp", "rdaudio"...
