==================================================================== # The release file for RDF-Core # ====================================================================

Version 0.51
February 19, 2007

• Makefile reporting dependencies in CPAN-compatible way
• added basic test suite
• minor fixes Version 0.50 July 14, 2006

  ---

• a major bug in storing language tags and datatypes for literals fixed (bug 3148, thanks to Pierluigi Miraglia and Gregory Williams), it affects all types of storages (Memory, DB_File, Postgres). The new version is NOT compatible with old storages, so you will have to serialize your data, create new storages and parse it back. Version 0.40 March 2, 2006

  ---

• some code cleanup (thanks to Gregory Williams)
• a new method equals() added to literal object, datatype and laguage tag are taken into account (bug 2306)
• escaping characters in rdf:about attribute fixed (bug 1630, thanks to Norman Walsh)
• rdf:nodeID is produced by serializer when necessary, instead of incorrect deanonymizing resource Version 0.31 August 11, 2004

  ---

• Typo in RDF::Core::NodeFactory fixed
• RDF::Core::Model::Serializer callback functions can be overriden now Version 0.30 March 14, 2003

  ---

  Specification changes:

• datatype and language information are handled wherever needed (parser, serializer, storages, literal object, NTriples output)
• RDF/XML: rdf:nodeID attribute is handled in parser
• RDF/XML: rdf:parseType="Literal" asserts typed literal
• RDF/XML: rdf:parseType="Collection" attribute value is handled

        Fixed bugs:
        - rdf namespace is prepended to about attribute in serializer
        - Namespace/local value separation is kept where
          RDF::Core::Resource->clone() is called. (reported by Dan Berrios)  

Version 0.20
October 14, 2002

• several bugs fixed
• external variables binding supported in query (prepare() and execute() methods)
• comments are allowed in query syntax
• query language syntax changes for (hopefully) better readability

Version 0.16
May 27, 2002

• a new module Schema is added, which provides access to RDF Schema

• parser recognizes and handles xml:base attribute (bug 771)
• parser bug with rdf:bagID fixed (bug 774)

• query results are not returned in array of rows, a callback function is called for each row instead
• query evaluation speed was improved by applying conditions as soon as possible
• DB_File storage handles SIGINT to protect data consistency
• DB_File storage has a new option Sync which says how often it should synchronize cache with disk
