OWLJessKB: A Semantic Web Reasoning Tool|
This is the homepage of OWLJessKB. OWLJessKB is a description
logic reasoner for the W3C's Ontology Web Language . The
semantics of the language is implemented using Jess, the Java Expert
System Shell . OWLJessKB is a successor to DAMLJessKB,
the webpage for which is here. Reasoning on the
DARPA Agent Markup Language is not supported in OWLJessKB; such
projects should continue to use DAMLJessKB.
Currently most of the common features of OWL lite, plus
some and minus some.
There are some very scant javadocs here.
Please feel free to look at the source code and ask questions
on the mailing list.
The following downloads are available (in reverse
chronological order). Archives are jar files. OWLJessKB works
from inside the jar or can be extracted to retrieve source code.

You will also need to download a few libraries upon which
OWLJessKB is dependent; they're listed in the following section.
As noted above, OWLJessKB uses both the Jena and Jess
libraries. Both are required in order to use OWLJessKB. We do not
currently package these libraries with the OWLJessKB distribution in
order to avoid licensing and installation issues. Both may be acquired
from the following links. Note that OWLJessKB was developed using the
stand-alone distribution of ARP2. It should be compatible with the
version of ARP2 packaged with Jena2. OWLJessKB has not been extensively
tested with ARP1's Java interface or parsed RDF model. It seems to work,
but there are many constructs which ARP1 cannot parse.
