 * categories: the subject field of an ontology can be specified using one or more categories
 * tasks
 * license models: you can select among various licences
 * formality levels: you can select among different formality levels:
 * vocabulary (list of words)
 * terminology (list of concepts with definitions)
 * taxonomy (terminology with subsumption hierarchy)
 * axiomatization (ontology with axioms beyond a pure subsumption hierarchy)
