- Regresssion test incorporates the RDF Core Positive Parser Tests except XMLLiteral & reification
- xml:base support was added in the parser.
- Use the --rdf=R flag to allow RDF to be parsed even when there is no enveloping <rdf:RDF> tag
- nodeid generated on RDF output
- Automatically generated terms with no URIs sort after anything which has a URI.
- Namespace prefix smarts on output - default ns used for that most frequently used.
- suppresses namespace prefix declarations which are not actually needed in the output.
- Cwm will also make up prefixes when it needs them for a namespace, and none of the input data uses one.-
- Will not use namespace names for URIs which do not have a "#". Including a "/" in the flags overrides.
