CDM Core: A Manufacturing Domain Ontology in OWL2 for Production and Maintenance
Ontology engineering is known to be a complex, time consuming, and costly process, in particular, if an ontology has to be developed from scratch, and respective domain knowledge has to be formally encoded. This paper presents the largest publicly available manufacturing ontology CDM Core in the standard formal ontology language OWL2 (available at: http:/sourceforge.net/projects/cdm core/ The CDM Core ontology has been developed within the European research project CREMA in close collaboration with the user partners in order to sufficiently cover the CREMA use case domains of metal press maintenance and automative exhaust production. CDM Core makes use of many relevant standard vocabularies and ontologies, with only about one fifth of its size being CREMA use case specific. The practical applicability of CDM Core for semantic annotation of domain related process models, sensor data and services has been approved by the user partners, and its quality according to selected common criteria of verification and validation was successfully evaluated. From the public release of the CDM Core, we expect to cover the lack of a base common ontology for the manufacturing domain, thanks to feedbacks from industrial reuse and improvements from the community.
