This is to announce the first release of 3store version 3, an alpha
release of 3store version 3. It breaks database compatability with 3store
version 2, but both versions can coexist on one machine.
Available from
http://triplestore.aktors.org/releases/ or
http://sourceforge.net/project/showfiles.php?group_id=64823&package_id=163670
The query language implemententation is fairly compete, but there is no
RDFS infererence support yet, hence the alpha status. At this stage I
would welcome feedback from users.
The major improvement in this version is SPARQL query processing.
Known bugs/ommisions:
* Nested OPTIONAL blocks (results are undefined)
* Nested UNION blocks (results are undefined)
* FROM and FROM NAMED (not implemented until I have a security system)
* Case sensitive regex matches not supported
(run without case sensitivity for now)
* RDQL queries do not allow the 4th "model" slot to be used.
See the README for more information.
TODO list:
* Implement RDFS inference
* Back compatibility with v2 XML results format
* Scalability testing and improvements (currently only tested to 10MT)
* FROM (NAMED) support
* More efficient protocol implementation (apache module or similar)
* SOAP support
