Raptor RDF Parser Toolkit 1.4.19

Raptor RDF Parser Toolkit 1.4.19 is a very serviceable software / Open Source C library that provides a set of parsers and serializers generating Resource Description Framework (RDF) triples by parsing syntaxes or serialize the triples into a syntax.

The supported parsing syntaxes are RDF/XML, N-Triples, TRiG, Turtle, RSS tag soup including all versions of RSS, Atom 1.0 and 0.3, GRDDL and microformats for HTML, XHTML and XML and RDFa. The serializing syntaxes are RDF/XML (regular, and abbreviated), Atom 1.0, GraphViz, JSON, N-Triples, RSS 1.0 and XMP.

Raptor was designed to work closely with the Redland RDF library (RDF Parser Toolkit for Redland) but is entirely separate. It is a portable library that works across many POSIX systems (Unix, GNU/Linux, BSDs, OSX, cygwin, win32). Raptor has no memory leaks and is fast.

Major Features:

1. Designed to integrate well with Redland
2. Parses content on the web if libcurl, libxml2 or BSD libfetch is available.
3. Supports all RDF terms including datatyped and XML literals
4. Optional features including parsers and serialisers can be selected at configure time.
5. Language bindings to Perl, PHP, Python and Ruby when used via Redland
6. No memory leaks
7. Fast
8. Standalone rapper RDF parser utility program

Enhancements:

• Many improvements to RSS tag soup (RSSes and Atom) parser and the RSS 1.0 and Atom serializers
• Several fixes and improvements to the N-Triples, RDFa and RDF/XML parsers and Turtle serializer
• Improved the use and configuration of static libxml functions for better compatibility
• Several Win32 portability fixes - Lou Sakey
• Many internal changes for upcoming Raptor V2 - primarily by Lauri Aalto
• Many other fixes and resilience improvements.
• Fixed:
• • Fix NFC check for legal combiner sequence
    
  • Error when raptor_new_uri() fails in Turtle parser
    
  • Invalid turtle output syntax on empty integer/double/decimal literals
    
  • Default/atom namespace in atom serializer output
    
  • strstr is called in raptor_parse_chunk() on a buffer string, where it should be called on a null-terminating string.
    
  • RSS serializer fixes for g++
    
  • Fix raptor_sequence_set_at() when setting beyond end
    
  • broken collection abbreviation in turtle serialization
    
  • Fix raptor_sax2_parse_chunk() calling raptor_log_error_to_handlers() with expat raptor_get_feature function does not return feature value
    
  • Fix RDFa parser problem when there is a subject and predicate specified on an element, but no child nodes for the object literal
    
  • Fix performance problems when turtle parsing with lots of namespaces
    
  • Fix RDF/XML Parser problem with legacy ordinal predicates
    
  • Avoid calling xsltSetDefaultSecurityPrefs()
