The following issue has been SUBMITTED. ====================================================================== http://bugs.librdf.org/mantis/view.php?id=495 ====================================================================== Reported By: normang Assigned To: ====================================================================== Project: Raptor RDF Syntax Library Issue ID: 495 Category: api Reproducibility: always Severity: major Priority: normal Status: new Syntax Name: RDFa & Turtle ====================================================================== Date Submitted: 2012-02-19 21:21 Last Modified: 2012-02-19 21:21 ====================================================================== Summary: RDFa parser produces unexpected results with CDATA sections and entity references Description: Consider the examples below.
Tests content1, 2, 4 and 5 are, I think wrong. For content1, 2, 4 and 5, the CDATA marked section is simply omitted. Although http://www.w3.org/TR/rdfa-syntax/ doesn't mention CDATA marked sections, there's nothing there that seems to warrant ignoring them. Tests content1, 2 and 5 produce XMLLiteral data which includes both elements and entities. However in each of the three cases, the Turtle output has the characters denoted by entities (the &<>) appearing literally in the rdf:XMLLiteral, making it not valid XML. Ie they're not escaped in any way. I can't find anything, in either http://www.w3.org/TR/REC-rdf-syntax/ (which I suppose is the definition of rdf:XMLLiteral) or http://www.w3.org/TeamSubmission/turtle/ which spells out what the content of an rdf:XMLLiteral should be, but I would be surprised if invalid XML is allowed. I don't know whether this is an RDFa parsing error or a Turtle serialisation error.
