Allows creation and edition of ontologies. Protégé is an ontology editor and framework, with support for the OWL 2 Web Ontology Language, that provides a suite of tools for ontology development and use. The tools range from creating the terminology (GUI, visualization, and versioning support) to deployment and application development (user feedback management, API, and application support). The software is also available as WebProtege, a Web-based tool for the collaborative development of OWL 2 ontologies.
An open source, platform-independent ontology editor developed and maintained by the Gene Ontology Consortium. Implemented in Java, OBO-Edit uses a graph-oriented approach to display and edit ontologies. OBO-Edit is particularly valuable for viewing and editing biomedical ontologies.
A high level application programming interface (API) for working with OWL ontologies. The OWL API is closely aligned with the OWL 2 structural specification. The OWL API supports parsing and rendering in the syntaxes defined in the W3C specification (Functional Syntax, RDF/XML, OWL/XML and the Manchester OWL Syntax); manipulation of ontological structures; and the use of reasoning engines.
Generates new ontology terms, term annotations and logical axioms. Ontorat assists for the building of an ontology and the creation of new terms and axioms are based on a specific ontology design pattern (ODP). This software enables the reuse and the storage of axiom setting files and input template files. It allows also the annotation of ontology terms by following design patterns.
Facilitates the use of both OWL API and OWL Reasoner API. OWLTools proposes a set of methods to manage OBO-style annotation properties and give access to gene ontology utilities. The application aims to provide an interface to run features allowing users to retrieve ancestor edges of a class, gather ontologies, apply several standard semantic similarity methods as well as the possibility to formulate query that uses a reasoner.
