Sequoia Reasoner


Sequoia is a consequence-based ontology reasoner that supports the SRIQ subset of OWL 2 DL — that is, it supports all OWL 2 DL features apart from nominals and datatypes. The system is released under an academic license that allows free use for noncommercial purposes.


Using EOLO

The reasoner is fully compliant with the OWL API, and it can also be used as a Protégé plugin.
