General Information
This record was deprecated on March 22, 2016 for the following reason(s): This resource is obsolete and has been replaced by the OBO Relations Ontology (

This record describes the original relations ontology (ID space "OBO_REL"), which was a direct translation of the 2005 RO paper into OBO format. It suffered a number of problems, such as lack of clarity in the semantics of class level relations. The OBO Relations Ontology (RO) has replaced this resource, and a description of how the two resources differ can be found at

Related Databases (3)
Rat Genome Database
The Rat Genome Database stores genetic, genomic, phenotype, and disease data generated from rat research. It provides access to corresponding data for eight other species, allowing cross-species comparison. Data curation is performed both manually and via an automated pipeline, giving RGD users integrated access to a wide variety of data to support their research.

A resource providing data on bioentities and their associated ontology terms for Plant Biology. The database provides access to ontology-based annotations of genes, phenotypes and germplasms from about 90 plant species. A number of internal and external ontologies are used to annotate the biological data available from this resource.

OBO Foundry
The Open Biological and Biomedical Ontology (OBO) Foundry is a collective of ontology developers that are committed to collaboration and adherence to shared principles. The mission of the OBO Foundry is to develop a family of interoperable ontologies that are both logically well-formed and scientifically accurate. To achieve this, OBO Foundry participants voluntarily adhere to and contribute to the development of an evolving set of principles including open use, collaborative development, non-overlapping and strictly-scoped content, and common syntax and relations, based on ontology models that work well, such as the Gene Ontology (GO). The OBO Foundry is overseen by an Operations Committee with Editorial, Technical and Outreach working groups.
