The Protégé-OWL editor is an extension
Protégé that supports the
Web Ontology Language (OWL)
. OWL is the most recent
development in standard ontology languages, endorsed by the
World Wide Web Consortium (W3C)
to promote the
Semantic Web vision
"An OWL ontology may include descriptions of classes, properties and their instances. Given such an ontology, the OWL
formal semantics specifies how to derive its logical consequences, i.e. facts not literally present in the ontology, but
entailed by the semantics. These entailments may be based on a single document or multiple distributed documents that have
been combined using defined OWL mechanisms" (see the
OWL Web Ontology Language Guide
The Protégé-OWL editor enables users to:
- Load and save OWL and RDF ontologies.
- Edit and visualize classes, properties, and SWRL rules.
- Define logical class characteristics as OWL expressions.
- Execute reasoners such as description logic classifiers.
- Edit OWL individuals for Semantic Web markup.
Protégé-OWL's flexible architecture makes it easy to configure and extend the tool. Protégé-OWL
is tightly integrated with Jena
and has an
open-source Java API
for the development of custom-tailored user interface
components or arbitrary Semantic Web services.
Further documentation about Protégé-OWL is available in the
of the Protégé-OWL Web site,
including the popular
Protégé OWL Tutorial
and the Protégé-OWL FAQ
