		   Rasqal RDF Query Library 0.9.11
		      http://librdf.org/rasqal/

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

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: working but the API is being modified and
extended.  It is a portable library and has been tested on multiple
POSIX systems and a variety architectures (x86, IA64, powerpc, alpha,
sparc) along with win32 and other systems.  It has no known memory leaks.

The main changes in this version since the last release 2005-06-09 are:

 * Updated to SPARQL Query Language for RDF W3C Working Draft, 2005-11-23
   making several additions and changes to the syntax and functionality.
 * Using ordering, distinct and limit with query results now works.
 * Created an enhanced API reference manual with gtk-doc
 * Many updates to the literal and expression handling.
 * Major internal source code re-organisation.

Detailed changes are given in the 0.9.11 release notes at
  http://librdf.org/rasqal/RELEASE.html#rel0_9_11

Rasqal 0.9.11 requires Raptor 1.4.8[2] or newer to provide RDF, web,
XML and URI support.  Rasqal can use either Raptor or Redland
1.0.0[1] or newer to provide a source of triples.  An optional
requirement is a POSIX regular expression library such as PCRE or one
built into the C library to handle regex matching.

Rasqal 0.9.11 was tested as working out-of-the-box (configure; make;
make check) against an installed Raptor 1.4.8 with the following
systems:

    alphaev67-unknown-linux-gnu - Debian GNU/Linux 3.0 on Alpha
    i386-pc-solaris2.9          - Sun Solaris 9 (SunOS 5.9) on x86
    i386-unknown-netbsdelf2.0.2 - NetBSD 2.0.2 on x86
    i686-pc-linux-gnu           - Debian GNU/Linux unstable on x86
    powerpc-apple-darwin8.4.0   - Apple OSX 10.4.4 on powerpc
    powerpc64-unknown-linux-gnu - SuSE Linux ES 9 on powerpc64
    sparc-sun-solaris2.9        - Sun Solaris 9 (SunOS 5.9) on sparc
    x86_64-unknown-linux-gnu    - Debian GNU/Linux unstable on AMD64
    x86_64-unknown-linux-gnu    - Redhat GNU/Linux Fedora Core 3 on AMD64

The release consists of the full sources and source RPM packages
which are also available from the Redland SourceForge mirror site at
  http://sourceforge.net/projects/librdf/

Redhat packages for Fedora Core 4 and Debian packages for unstable
will be made available after release.

The main web site lets you browse and check out the latest version of
the sources in CVS and use Rasqal in various demos (as part of
Redland).  Rasqal will be migrating to use Subversion after this
release, the latest state is recorded at http://svn.librdf.org/
