05:49, 2 Aug 2001 UTC | Edd Dumbill

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.
