You can get the OWL version of OGMS at http://purl.obolibrary.org/obo/ogms.owl.

The development version of OGMS can be found at http://purl.obolibrary.org/obo/ogms/dev/ogms.owl.

The Ontology for General Medical Science (OGMS) is an ontology of entities involved in a clinical encounter. OGMS includes very general terms that are used across medical disciplines, including: 'disease', 'disorder', 'disease course', 'diagnosis', 'patient', and 'healthcare provider'. OGMS uses the Basic Formal Ontology (BFO) as an upper-level ontology. The scope of OGMS is restricted to humans, but many terms can be applied to a variety of organisms. OGMS provides a formal theory of disease that can be further elaborated by specific disease ontologies. This theory is implemented using OWL-DL and OBO Relation Ontology relations and is available in OWL and OBO formats.

OGMS is based on the papers Toward an Ontological Treatment of Disease and Diagnosis and On Carcinomas and Other Pathological Entities. The ontology attempts to address some of the issues raised at the Workshop on Ontology of Diseases (Dallas, TX) and the Signs, Symptoms, and Findings Workshop(Milan, Italy). OGMS was formerly called the clinical phenotype ontology. Terms from OGMS hang from the Basic Formal Ontology.

NEWS: The OGMS-based Cardiovascular Disease Ontology was the winner of this year's Ontology Competition at the FOIS (Formal Ontology in Information Systems) conference in Rio de Janeiro. http://fois2014.inf.ufes.br/p/paper-and-competition-awards.html

We are always interested in application-specific use cases for OGMS, such as those described here. Existing and planned extensions of OGMS include:

• Sleep Domain Ontology (SDO)
• Infectious Disease Ontology (IDO) and its suite of extensions.
• Ontology of Medically Relevant Social Entities (OMRSE)
• Vital Sign Ontology (VSO)
• Mental Diseases
• Examples of OGMS applied to specific diseases.
• Oral Health and Disease ontology
• Cardiovascular Disease Ontology
• Mental Functioning Ontology
• Ontology for Newborn Screening Follow-up and Translational Research
• Drug Ontology
• Model for Clinical Information (MCI)
• Ocular Disease Ontology (ODO)
