The Web Ontology Language (OWL) is a family of knowledge representation languages for authoring ontologies.Ontologies are a formal way to describe taxonomies and classification networks, essentially defining the structure of knowledge for various domains: the nouns representing classes of objects and the verbs representing relations between the objects.
Multimedia Ontology language (M-OWL) is an ontology representation language that enables such perceptual modeling. It assumes a causal model of the world, where observable media features are caused by underlying concepts. In MOWL, it is possible to associate different types of media features in different media format and at different levels of ...
The NeOn Toolkit is an open source, multi-platform ontology editor, which supports the development of ontologies in F-Logic and OWL/RDF.The editor is based on the Eclipse platform and provides a set of plug-ins (currently 20 plug-ins are available for the latest version, v2.4) covering a number of ontology engineering activities, including Annotation and Documentation, Modularization and ...
Semantic Application Design Language (SADL) is an English-like open source language for building formal models composed of an OWL ontology, rules expressed in terms of the ontological concepts, queries for retrieving information from the model, and tests to validate and re-validate model content and entailments (implications).
OWL-S is an ontology built on top of Web Ontology Language (OWL) by the DARPA DAML program. [1] It replaces the former DAML-S ontology. "OWL-S is an ontology, within the OWL-based framework of the Semantic Web, for describing Semantic Web Services. It will enable users and software agents to automatically discover, invoke, compose, and monitor ...
OWL and RDF were initially defined to provide an XML-based machine to machine interchange of metadata and semantics. ODM now integrates these into visual modeling, giving a standard well-defined process for modeling the ontology, as well as, allowing for interoperability with other modeling based on languages like UML, SysML and UPDM.
Protégé is a free, open source ontology editor and a knowledge management system. The Protégé meta-tool was first built by Mark Musen in 1987 and has since been developed by a team at Stanford University. [4] The software is the most popular and widely used ontology editor in the world. [5] [6] [as of?]
The OBO file format is a biology-oriented language for building ontologies. It is based on the principles of Web Ontology Language (OWL). As a community effort, standard common mappings have been created for lossless roundtrip transformations between Open Biomedical Ontologies (OBO) format and OWL.
