The OWL 2 Web Ontology Language, informally OWL 2, is an ontology language for the Semantic Web with formally defined meaning. OWL 2 ontologies provide classes, properties, individuals, and data values and are stored as Semantic Web documents. OWL2 is a W3C Recommendation and is a
I noticed the power of OWL2 knowledge representation in complex software projects, where it was necessary to relate many facts with each other. OWL2 provides a way to relate these facts, and provides flexibility, changeability of these facts. It also provided a possibility to find referring facts, which is extremely useful for impact analysis.
