OBIOntology for Biomedical Investigations

The Ontology for Biomedical Investigations (OBI) project is developing an integrated ontology for the description of biological and clinical investigations. The ontology will represent the design of an investigation, the protocols and instrumentation used, the material used, the data generated and the type analysis performed on it. Currently OBI is being built under the Basic Formal Ontology (BFO).

MPMammalian Phenotype Ontology

The Mammalian Phenotype Ontology (MP) classifies and organises phenotypic information related to the mouse and other mammalian species. This ontology has been applied to mouse phenotype descriptions in various databases allowing comparisons of data from diverse mammalian sources. It can facilitate in the identification of appropriate experimental disease models, and aid in the discovery of candidate disease genes and molecular signaling pathways.
