Common Core Ontologies

The Common Core Ontologies (CCO) comprise twelve ontologies which are designed to represent and integrate taxonomies of generic classes and relations across all domains of interest.

CCO is a mid-level extension of Basic Formal Ontology (BFO), an upper-level ontology framework widely used to structure and integrate ontologies in the biomedical domain (Arp, et al., 2015). BFO aims to represent the most generic categories of entity and the most generic types of relations that hold between them, by defining a small number of classes and relations. CCO then extends from BFO in the sense that every class in CCO is asserted to be a subclass of some class in BFO, and that CCO adopts the generic relations defined in BFO (e.g., has_part) (Smith and Grenon, 2004). Accordingly, CCO classes and relations are heavily constrained by the BFO framework, from which it inherits much of its basic semantic relationships.

The CCO provide semantics for concepts and relations that are used in most domains of interest. The utility of the CCO comes from preventing BFO-compliant domain-specific ontologies from needlessly duplicating common concepts or from forcing such ontologies to include concepts outside of their domain (e.g. organization in the Ontology of Biomedical Investigations).

This utility has been realized by a number of U.S. Government sponsored projects in which either existing BFO compliant ontologies were aligned to the CCO or domain ontologies were created by using the CCO as a starting point and adding classes and properties as needed.

The names of a sample of these domain ontologies are provided in the list below.

The U.S. Government holds Government Purpose Rights on all of these domain ontologies. To obtain one or more of these domain ontologies for a government purpose it will be necessary for a government representative to contact the government sponsor of the development of the ontology. CUBRC can faciliate these connections so if interested please use the contact link at the bottom of https://www.cubrc.org/index.php/data-science-and-information-fusion/ontology .
