RDFStore version 0.50 has been released and available on CPAN. This is 
major release
of the toolkit after 3 years - most of the code has been re-written in 
pure ANSI C and a new
native indexing model [1] for RDF has been built in. Several RDF based 
shallow
Semantic Web applications [2] [3] has been successfully built using the 
toolkit from
Asemantics S.r.l and its partners.

Major changes include:

- pure ANSI C and native RDF hash-storage and indexing
- simple RDQL support
- native storage Unicode, free-text, stemming, xml:lang and 
rdf:datatype indexing
- RDF/XML parser made compliant to latest RDF/XML spec - all positive 
RDF-Core
tests are being passed successfully [4]
- simple N-Triples parser
- triples source/provenance support
- fetch_object / CBD support [5]
- RDF/XML, N-Triples and RDF-for-XML [6] output for RDQL queries

Various misc demos are available at

    http://demo.asemantics.com/rdfstore/

In addition to CPAN the code is also available from SourceForge CVS [7] 
repository - and
as tarballs directly from toolkit Web site [8].

Future developments will include support for upciming DAWG/BRQL query 
language, pure C query
interface, ODBC and JDBC APIs. Together with a Jena / Java and PHP 
front-ends.

The project is full work in progress - comments, bug reports and 
suggestions are welcome
