RDF/XML Handling in Jena

This section details the Jena RDF/XML parser. ARP is the parsing subsystem in Jena for handling the RDF/XML syntax.

• ARP Features
• Using ARP without Jena
• Using other SAX and DOM XML sources

ARP Features

• Java based RDF parser.
• Compliant with RDF Syntax and RDF Test Cases Recommendations.
• Compliant with following standards and recommendations:
  • xml:lang
    xml:lang is fully supported, both in RDF/XML and any document embedding RDF/XML. Moreover, the language tags are checked against RFC1766, RFC3066, ISO639-1, ISO3166.
  • xml:base
    xml:base is fully supported, both in RDF/XML and any document embedding RDF/XML.
  • URI
    All URI references are checked against RFC2396. The treatment of international URIs implements the concept of RDF URI Reference.
  • XML Names
    All rdf:ID's are checked against the XML Names specification.
  • Unicode Normal Form C
    String literals are checked for conformance with an early uniform normalization processing model.
  • XML Literals
    rdf:parseType='Literal' is processed respecting namespaces, processing instructions and XML comments. This follows the XML exclusive canonicalizations recommendation with comments.
  • Relative Namespace URI references
    Namespace URI references are checked in light of the W3C XML Plenary decision.
• Command-line RDF/XML error checking.
• Can be used independently of Jena, with customizable StatementHandler.
• Highly configurable error processing.
• Xerces based XML parsing.
• Processes both standalone and embedded RDF/XML.
• Streaming parser, suitable for large files.
• Supports SAX and DOM, for integration with non-file XML sources.
