Protégé provides a suite of tools to construct domain models and knowledge-based applications with ontologies. At its core, Protégé implements a rich set of knowledge-modeling structures and actions which support the creation, visualization, and manipulation of ontologies in various representation formats. It can be customized to provide domain-friendly support for creating knowledge models and entering data, and can be extended by way of a plugin architecture and a Java-based API for building knowledge-based tools and applications.

Release Notes: It is now possible for users to download and/or update plug-ins even when the Protege distribution is read-only. The annotation editor now remembers which tab was last selected. A bug in the ontology repository mechanism that caused some valid XML catalog files to be rejected and a bug that caused the save operation to add extra axioms from imported to importing ontologies were fixed.
Release Notes: This release improves the interface for the Active Ontology tab to be more readable. Launching the Protege application now opens an empty ontology instead of a welcome screen, to be standard with popular applications. Support has been for Java code generation. Protege no longer requires administrative privileges to run on Windows machines.
Release Notes: The default installation now includes support for executing SPARQL queries from the user interface. This release makes some improvements to the "Ontology annotations" view to more clearly indicate language and type information. It bundles an updated version of the Apache Felix Framework (4.0.1). It fixes a problem with the installer which was preventing users from being able to perform silent uninstalls.
