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.

There is a newer version: 1.3.8.4

A package containing various binary and unary operations on automaton 
objects.

Documentation

This package offers a lot of standard transformations on automata objects:
concatenation:
concatenate two automaton so that L(A.B) = L(A).L(B),
union:
union of two automaton , L(A+B) = L(A) U L(B),
star closure:
the standard kleene-closure operator, L(A*) = epsilon U L(A).L(A*)
minimization:
compute the minimal - canonical - DFA from a given DFA
determinization:
make an automaton deterministic: Each state has at most one transition labelled with a given letter,
epsilon transition removals:
Removes transition labelled with null while keeping the same language
complementation:
complement the language over the alphabet of the automaton, for an alphabet X, L(-A-)=X*\L(A)
synchronization product:
Compute the synchronization product of two automaton, also named mixed product
parametric intersection:
compute the intersection of two automaton with a synchronization object,
normalization:
normalize an automaton: One start state, one end state, no incoming transitions on start state
prefix closure:
an automaton with all states made terminal
pruning:
remove all states that are neither accessible from a start state nor can reach a terminal state
projection over an alphabet:
remove all transitions from an automaton that are not in an alphabet
reversal:
reverse the language of an automaton so that it recognizes mirrored words from the original automaton.
shuffle product:
compute all possible interleavings of words from two automaton
These transformations are usually not very efficient so that applying any one of them on large automaton may yield poor performances. Possible exceptions are the epsilon transition removal, synchronization products and intersections which compute the results using reachable states set only so that the cartesian product of the involved automata is not computed.

Work is underway to improve ultimately performance of this library.
