Integrity validation in semantic engineering design environment

A collaborative engineering design environment has been devised based on semantic Web technologies. The Semantic Engineering Design Environment (SEDE) consists of Engineering Ontology, Design Rules, Design Database, and Design Data Web Service. The Design Data Web Service provides users APIs (Application Programming Interface) so that distributed Design Participants interface each other. The domain knowledge of design objects can be logically expressed by OWL (Web Ontology Language). Design rules regarding change management are encoded in XQuery and stored as database triggers. Once design data changes, associated design rules will be validated by database systems. In this paper we introduce the overall architecture of the collaborative engineering design environment and present working scenarios with examples.
