ARP Features

• Java based RDF parser.


• Compliant with the last call candidate
  
  syntax and
  
  
  test cases
  editors' working drafts.


• Compliant with following standards and recommendations:
  

  
  
  

  daml:collection

  
  

  
  
  rdf:parseType='daml:collection' is supported.

  
  
  

  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 follows the approach of anyURI in
  XML Schema Datatypes.
  

  
  
  

  XML Names

  
  

  All rdf:ID and rdf:BagID's are checked against
  the XML Names specification.

  
  
  

  International URI refs

  
  

  rdf:about, rdf:ID and rdf:BagID's are processed according to
  the Character Model working draft.

  
  
  

  Unicode Normal Form C

  
  

  String literals and URIs 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, and
  treating namespace (re)declarations as visible uses of the namespace.

  
  

  Relative Namespace URI references

  
  

  Namespace URI references are checked in light of
  the W3C XML Plenary
  decision.

  
  
  

  aboutEach

  
  

  Is no longer supported, in line with working group decisions.
