FAIRsharing record for: OBO ReLationship

This FAIRsharing record describes: 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 https://github.com/oborel/obo-relations/wiki/DifferencesWithOldRO.
