		   Rasqal RDF Query Library 0.9.15
		      http://librdf.org/rasqal/

Rasqal is a free software / Open Source C library that provides
querying of Resource Description Framework (RDF) with multiple query
languages syntaxes, query construction by API and execution of
queries returning results as bindings, boolean, RDF graphs/triples
or syntaxes.  It supports the SPARQL and RDQL query languages.

Rasqal is designed to work closely with the Redland[1] RDF library
and the Raptor[2] RDF parsing and serializing library but is entirely
separate from both.

Rasqal is beta quality: mostly working but the API is still changing.
It is a portable library and has been tested on multiple POSIX
systems and architectures.  Rasqal has no known memory leaks.

The main changes in this version since the last release 2007-04-22 are:
 * Many updates for supporting W3C SPARQL Proposed Recommendation.
   Passes over 92% of the DAWG SPARQL Test Suite.
 * Many query engine improvements.
 * Substantial improvements to datatypes support and evaluation.
 * Many improvements and fixes for use in low-memory situations
 * Several new APIs were added including a new XSD decimal class
 * Fixed issues: #0000190, #0000191, #0000193, #0000196, #0000197,
   #0000198, #0000199, #0000200, #0000201, #0000203, #0000204, #0000219,
   #0000220, #0000221, #0000225, #0000234, #0000235 and #0000236

Rasqal 0.9.15 requires Raptor 1.4.16[2] or newer to provide RDF, web,
XML and URI support. Optional requirements include a POSIX regular
expression library such as PCRE or one built into the C library to
handle regex matching and a multi-precision decimal library such
as GNU MP or MPFR.

Binary deb packages for Debian unstable will be made available
shortly via the standard debian archive and download.librdf.org.

Sources and binaries are also available from the Redland
SourceForge mirror site at http://sourceforge.net/projects/librdf/
