		   Rasqal RDF Query Library 0.9.2
	     http://www.redland.opensource.ac.uk/rasqal/

               Supported by EU IST project SWAD-Europe
		  http://www.w3.org/2001/sw/Europe/

Rasqal is a free software/Open Source C library that handles RDF
query syntaxes, query construction and query execution returning
result bindings.  It currently handles RDF Data Query Language
(RDQL).  Rasqal was designed to work closely with the Redland[1] RDF
library and Raptor[2] RDF parsing library but is entirely separate.

This is a minor release of Rasqal which is beta quality: working but
the API is being modified and extended.  Rasqal is a portable library
and has been tested on multiple POSIX systems and a variety
architectures (x86, IA64, powerpc, alpha, sparc).  It has no known
memory leaks and is suitable for embedding in long running
applications.

The main changes this release are:

 * Fix casts for C++
 * Add win32 skeleton header file
 * Fix a memory leak when using redland inside rasqal

Detailed changes are given in the 0.9.2 release notes at
http://www.redland.opensource.ac.uk/rasqal/RELEASE.html#rel0_9_2

Raptor 0.9.2 requires Raptor 1.3.1[2] or newer to provide RDF parsing
support and also can use either Raptor or Redland[1] 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.
This release was tested as working out-of-the-box (configure; make;
make check) against an installed Raptor 1.3.1 or newer with the
following systems:

    i386-unknown-freebsd4.10    - FreeBSD 4.10-PRERELEASE on x86
    i686-pc-linux-gnu           - Redhat GNU/Linux Fedora Core 2 on x86

The release consists of the full sources, RPM binaries and source RPM
packages for RedHat GNU/Linux Fedora Core 2.
These are also available from the Redland SourceForge mirror site at
  http://sourceforge.net/projects/librdf/
Debian packages should be made available shortly.

The main web site lets you browse and check out the latest version of
the sources in CVS.

I post updates about Rasqal, Redland and Raptor to the redland-dev list
