Datashapes.org content negotiation

[ashleysommer]

HTTP GET request to http://datashapes.org/schema with header Accept: text/turtle or Accept: application/rdf+xml both return the schema.html response, with HTML content, and content-type is always "text/html".

That breaks import statements in RDF that look like this:

<http://datashapes.org/sh/tests/core/complex/personexample.test>
  rdf:type owl:Ontology ;
  rdfs:label "Test of personexample" ;
  owl:imports <http://datashapes.org/schema> ;  #<-- This returns HTML

Note, after changing it to "http://datashapes.org/schema.ttl" works, however there are other inconsistencies after that:

• "http://datashapes.org/dash" works as expected, it returns exactly the format from the Accept header, and response content-type is correct
• "http://topbraid.org/tosh" does not include a Content-Type response header. It will return RDF in either text/turtle or rdf/xml however if you use an Accept header like "Accept: text/turtle, application/rdf+xml", it will return one of those formats but there is no way to know which one without attempting to parse the file.
