Welcome to the Protege Ontology Library!

This page is organized into the following groupings:

If your ontology is available in multiple formats, please feel free to link to it from multiple sections.

Please make insertions in alphabetical order. Thank you !!!


OWL ontologies

Information on how to open OWL files from the Protege-OWL editor is available on the main Protege Web site. See the Creating and Loading Projects section of the Getting Started with Protege-OWL Web page. Other ways to search for OWL ontologies include using Google: http://www.google.com/search?q=filetype:owl+owl, or the new Semantic Web search engine called Swoogle.


  • AIM@SHAPE Ontologies: Ontologies pertaining to digital shapes. Source: AIM@SHAPE NoE - Advanced and Innovative Models And Tools for the development of Semantic-based systems for Handling, Acquiring, and Processing knowledge Embedded in multidimensional digital objects.
  • MOD Ontology: MOD stands for Metadata for Ontology Description and publication. MOD proposes a set of metadata elements which can be used to describe the ontologies, for instance, in ontology libraries and repositories. Like any other resources, ontologies also need to be described. The proper descriptions of the ontologies will enable us in discovering, identifying and selecting the right ontologies from the ontological libraries, and repositories. The details of this ontology can be found here. Contributed by Biswanath Dutta DRTC, Bangalore.
  • bhakti.owl: An OWL ontology for the transcendental states of consciousness experienced by practitioners of bhakti-yoga, a form of Vedic consciousness engineering.

  • Monetary_ontology_0.1d.zip: A zipped Protégé project of an ontology for currency creation and use. Also contains an "owl". The objective is an active description of all forms of "money" from barter to clearing systems, from precious metal coinage to debt-based fiat. It is oriented towards designers of payment systems and community currency systems. Here is a preview GIF image ! First begun 2008/05/04 and last updated 2008/05/12. v0.0 Contributed by Martin "Hasan" Bramwell
  • MR-MPS-SW : Enterprise Ontologies as a complementary tool to support the adoption of software process quality models. The model selected for this work was the Reference Model MPS for software development (RM-MPS-SW), which is part of the Brazilian Software Process Improvement Program (MPS.BR). The RM-MPS-SW was developed focusing micro, small and medium-sized enterprises (MSMEs), although it is completely suited to large organizations. In this context, this work presents a methodology for the ontology development on the levels G and F of the RM-MPS-SW. Concepts of the PMBOK (Project Management Body of Knowledge) are included to support adherence to its principle by software companies. The inclusion of BSC (Balanced Scorecard) indicators approximates the model with the strategic planning of the company. The intention is that this methodology can be used as a basis for the representation of the other MPS-SW levels and other software process models.
  • Communication Network A domain ontology of the SNMP-managed TCP/IP-based communication network system. Contributed by Sameera Abar
  • New Testament Names: A semantic knowledge base describing named things (people, places, and other classes) in the New Testament, as well as their attributes and relationships. It includes both an ontology and a substantial amount of instance data. NTNames is part of SemanticBible.org.

Frame-based ontologies

In the context of this page, the phrase "frame-based ontologies" loosely refers to ontologies that were developed using the Protege-Frames editor. For more information on how to open an ontology from the Protege-Frames editor, see the Protege-Frames User's Guide.
