The Open Biological and Biomedical Ontologies (OBO) Foundry is a group of people who build and maintain ontologies related to the life sciences. [1] The OBO Foundry establishes a set of principles for ontology development for creating a suite of interoperable reference ontologies in the biomedical domain.
Ontology Design Patterns portal [73] is a wiki repository of reusable components and practices for ontology design, and also maintains a list of exemplary ontologies. Protégé Ontology Library [74] contains a set of OWL, Frame-based and other format ontologies. SchemaWeb [75] is a directory of RDF schemata expressed in RDFS, OWL and DAML+OIL.

The MIT 70 is the lowest profile Coast Guard-approved front entry inflatable life jacket on the market, and a dream for boaters who hate life jackets getting in the way of their movement.
"The OBO Foundry: coordinated evolution of ontologies to support biomedical data integration". Nature Biotechnology. 25 (11): 1251– 5. doi:10.1038/nbt1346. PMC 2814061. PMID 17989687. OBI uses the basic formal ontology [3] upper-level ontology as a means of describing general entities that do not belong to a specific problem domain. As such ...
