That would apply to the Open Annotation situation as well.

Our context defines prefixes for skos, dc, dcterms, content in rdf,
foaf and so on.
It also defines names for the predicates used from those ontologies by
typical uses of the data model.

eg, from http://openannotation.org/spec/core/publishing.html#Serialization:

{"@context" : {
   "oa" :     "http://www.w3.org/ns/oa#",
   "cnt" :    "http://www.w3.org/2011/content#",
   "dc" :     "http://purl.org/dc/elements/1.1/",
   "dcterms": "http://purl.org/dc/terms/",
   "dctypes": "http://purl.org/dc/dcmitype/",
...
    "chars" :        "cnt:chars",
    "bytes" :        "cnt:bytes",
    "format" :       "dc:format",
...
  }
}

So we should ask for our own context document? Or define these in our
ontology document?
