RdfXmlParser
in package
implements
Parser, QuadIterator
Uses
TmpStreamParserTrait
Streaming RDF-XML parser. Fast and with low memory footprint.
Known deviations from the RDF-XML specification:
- Doesn't resolve "/.." in relative IRIs.
- Doesn't support rdf:Seq shorthand syntax
- Doesn't support rdf:Collection shorthand syntax
