Extension Modules from the Common Core Ontologies, curated by Cameron More and other NCOR ontologists, and openly free to use by anybody for anything.
This module extends CCO to reason over manufacturing entities, but currently contains terms to reason over vehicles, models, years, and major manufacturers. My core strategy is to assert that manufacturers like General Motors are instances of some cco:IncorporatedOrganization that is the 'agent in' some Act of Artifact Processing. Artifact Models, such as Accord or Civic, specify the Artifacts that are produced, and those models are the specified input of the Act of Manufacturing. The user manual can be found on the wiki here.
