Download

You can download a snapshot of the Subversion repository, triple-20040922.tar.gz. Note that the current version has more features (i.e. Java integration, RDF/N3 import, Remove operation for facts and rules...), and is Linux-only.

Previous versions:

• triple-20040311.tar.gz: switched to XSB 2.6, results are returned as Java objects or RDF, facts and rules can be removed, linux-only.
• triple-20020314.zip or triple-20020314.tar.gz: switched to Jena 1.3.2 and XSB 2.5 (you need to upgrade to XSB 2.5 from older versions); UML (XMI) example added; 'triple -tripledump' added; servlet for DAML+OIL added;
• download/triple-20020307.zip or triple-20020307.tar.gz: added 'triple -rdfdump' (allows models to be dumped as RDF files); servlet version added
• triple-20020304.zip or triple-20020304.tar.gz: added support for external inference engines; RACER and FaCT DL classifier support (thus making TRIPLE a DAML+OIL query language; DAML+OIL standalone version for analyzing and visualizing DAML+OIL ontologies
• triple-20020212.zip: added RDF import and DAML+OIL animals example
• triple-20020211.zip: initial command line version
