In contrast with the centrally-organised curation of the Gene Ontology, many biological ontologies are developed by loosely-organised groups who develop their ontology remotely. These groups tend to be formed from scientists and bio-informaticians from research groups with a common interest, who want to create a resource that will be useful to the community, rather than being formally mandated.
