An Ontology Model for Manufacturing Grid Service by Extending OWL-S

Manufacturing grid is a new pattern developed to answer unprecedented challenges in manufacturing industry, one of the most important foundations of which is encapsulating or modeling manufacturing resources into grid service. But this kind of grid service is restricted by ambiguous and insufficient service description. This paper presents an ontology model, called M-service profile ontology, which provides the framework for explicitly encoding semantics of domain-specific engineering information. The model is generated by extending OWL-S with two classes. One is ManufacturingProfile class which provides formal engineering indexes needed during collaborative work. Anther is the QoSProfile class which provides a mechanism to represent quality of service. This ontology model enriches semantic descriptions of grid service which will be very conducive for later service discovery and management.
