Representation of regulation in the Gene Ontology (biological process) 
We have created a standard template for the definition of classes for the regulation of a biological process. This includes the definitions for positive and negative regulation. The equivalence axiom templates are "GO:0065007 and 'regulates' some X" (regulation), "GO:0065007 and 'negatively_regulates' some X" (negative regulation), and "GO:0065007 and 'positively_regulates' some X" (positive regulation), where X is a biological process.
