HermiT is reasoner for ontologies written using the Web
Ontology Language (OWL). Given an OWL file, HermiT can determine whether or
not the ontology is consistent, identify subsumption relationships between
classes, and much more.
This is the maven build of HermiT and is designed for people who wish to use
HermiT from within the OWL API. It is now versioned in the main HermiT
version repository, although not officially supported by the HermiT
developers.
The version number of this package is a composite of the HermiT version and
an value representing releases of this packaged version. So, 1.3.7.1 is the
first release of the mavenized version of HermiT based on the 1.3.7 release
of HermiT.
This package includes the Jautomata library
(http://jautomata.sourceforge.net/), and builds with it directly. This
library appears to be no longer under active development, and so a "fork"
seems appropriate. No development is intended or anticipated on this code
base.
