music-annotation-pattern's Issues

inconsistent ontology - propertyChainError when running reasoner

The property "isAnnotatorOf" is malformed.
The intended meaning is to link the annotator of a MusicAnnotation to each MusicObservation linked with it.

It should be converted to
:isAnnotatorOf o :includesMusicObservation SubPropertyOf :isAnnotatorOf (the chain is moved to :isAnnotatorOf). To avoid inconsistencies, the domain axioms on :hasAnnotator, the range axiom on :isAnnotatorOf and the disjointness axioms on both properties needs to be removed.

For reference, the error using Hermit is

ERROR  16:13:14  An error occurred during reasoning: The given property hierarchy is not regular.
There is a cyclic dependency involving property <http://purl.org/andreapoltronieri/music-annotation-pattern/isAnnotatorOf>.
java.lang.IllegalArgumentException: The given property hierarchy is not regular.
There is a cyclic dependency involving property <http://purl.org/andreapoltronieri/music-annotation-pattern/isAnnotatorOf>
