Ontology term

From Schemalet Wiki

The Ontology_term class defines references to a single entry from an ontology or a controlled vocabulary. Other classes can reference to this Ontology_term to harmonize naming of concepts. Each term should have a local, unique label. Good practice is to label it 'sourceid:term', e.g. 'MO:cell' If no suitable ontology term exists one can define new terms locally in which case there is no formal accession for the term. In those cases the local name should be repeated in both term and termAccession. Maps to FuGE::OntologyIndividual; in MAGE-TAB there is no separate entity to model terms
