Jeremy Carroll has announced ARP, Another RDF Parser, released by HP Labs in Bristol, UK, home of the popular Jena Java RDF API.

ARP will be the default RDF/XML parser in future releases of Jena. Distinguishing features include:

• compliance with latest working group clarifications.
  • compliance with following standards and recommendations:
  • RDF model and syntax
  • rdf:parseType="daml:collection"
  • xml:base, both in the RDF and its embedding document.
  • W3C XML plenary decision on relative namespace URIs.
  • rdf:aboutEach for containers of user defined types.
• command-line RDF/XML to N-triple functionality.
• command-line RDF/XML error checking.
• streaming parser, suitable for large files.

Describing the parser's design, Carroll writes that it is "based on a modular XML InfoSet design," using SAX2 to tokenize the InfoSet, and utilizing a JavaCC generated RDF parser with a grammar over the InfoSet.
