The following issue has been SUBMITTED. ====================================================================== http://bugs.librdf.org/mantis/view.php?id=516 ====================================================================== Reported By: normang Assigned To: ====================================================================== Project: Raptor RDF Syntax Library Issue ID: 516 Category: api Reproducibility: always Severity: minor Priority: normal Status: new Syntax Name: ====================================================================== Date Submitted: 2012-07-16 12:40 Last Modified: 2012-07-16 12:40 ====================================================================== Summary: rdfxml-xmp output generates prohibited syntax Description: When converting from Turtle to the XMP profile of RDF/XML, librdf generates syntax which is prohibited by the XMP standard. See below.
The rdfxml-xmp output contains the rdf:_1... properties which were included in the input. However, the XMP specification, ISO 16684-1:2011(E) (available at <http://www.adobe.com/devnet/xmp.html>) says: 7.9.3.3 rdf:_n elements and attributes RDF allows a sequence of rdf:li elements to be replaced with elements of the form rdf:_1, rdf:_2, and so on. Because these are unique names, element-to-attribute substitution similar to 7.9.2.2, “rdf:Description with property attributes”, is also allowed in general RDF. The rdf:li element shall be used in XMP and the rdf:_n form shall not be used in XMP. I believe, therefore, that the rdfxml-xmp serialiser should translate rdf:_n properties into rdf:li properties. The workaround is to use rdf:li properties in the input.
