IDO
The Industrial Data Ontology (IDO) is a W3C OWL 2 ontology. The IDO is intended for use in all life cycle phases of industrial assets and processes, to build vocabularies and manage asset models that employ Reference Data Libraries (RDLs).
IDO is suitable as a “top-level” ontology for industrial data terminology that defines generic terms for things that exist in more than one industrial domain. The ontology has previously been deployed successfully in the oil and gas industry under the title of ISO TR 15926-14.
IDO is the initial part of the new multipart ISO standard ISO/NP 23726 Ontology Based Interoperability with the number ISO/NP 23726-3. The initial working draft of IDO is available here.
