Bug#632836: Incorrect qname definition in TRiG parser
Package: libraptor2-0
Version: 2.0.3-1
Severity: normal
Tags: patch upstream
Forwarded: http://bugs.librdf.org/mantis/view.php?id=451
Hello,
Raptor2 TRiG does not parse some qnames properly. This poses a problem for
soprano [1] and the whole KDE stack. Could you include an attached patch or put
more pressure on upstream to include it & release new upstream version?

Problem: QName in Turtle syntax are different from QName in XML Namespaces.
It Turtle qname can miss prefix, local_part or both ( http://www.w3.org/TeamSubmission/turtle/#qname ). So if
@prefix nie: <blablabal> .
@prefix : <http://soprano.sf.net/testdata/> .
then the following
nie:
nie:xxx
:yyy
are all valid qnames. ( Unlike XML Namespaces, where nie: is not a valid QName )
Currently term "nie:" is not recognized as valid qname when used as graph
name. This issue has made all nepomuk ontologies invalid. Test data are given
in "Steps to reproduce" field.
