Description

The MIME / media / content types for N3 and Turtle are currently defined as text/rdf+n3 and application/x-turtle respectively: http://repo.aduna-software.org/svn/org.openrdf/sesame/trunk/core/rio/api/src/main/java/org/openrdf/rio/RDFFormat.java .

They need to be updated to text/n3 and text/turtle. For Turtle see the latest specification at http://www.w3.org/TeamSubmission/turtle/#sec-mediaReg . The N3 specification is a bit buggy with regard to that, it switches between text/rdf+n3 and text/n3: http://www.w3.org/TeamSubmission/n3/ . However see also http://www.w3.org/blog/SW/2008/01/15/w3c_team_submission_on_n3_and_turtle , http://chatlogs.planetrdf.com/swig/2009-04-01.html#T14-00-16 and some more discussion on http://lists.w3.org/Archives/Public/semantic-web/2009May/0021.html .

Since RDFFormat accepts a collection of MIME types perhaps it would be even better to add the old ones as well so that the right parser can be selected for data served with the old types. For Turtle the type application/turtle could be added to such a collection as well, as it was the primary type mentioned on http://www.dajobe.org/2004/01/turtle/2007-11-20/#sec-mime .
