 The Occupation Ontology (OccO) is an ontology in the domain of human occupations. OccO is an initial ontological presentation of information taken from a standardized occupation taxonomy, the US Standard Occupational Classification (SOC) as enhanced by the **O*Net** system.  These systems have been developed by the following US Federal agencies:
