Product information modeling based on parts library standard

STEP (ISO 10303) described product model information for life cycle. It was the base of the product data exchange, but there was lack of advanced semantic express. Parts Library Standard (PLIB, ISO13584) studied the rational express and exchange of computational parts library information based on design methodology, and shared the product resource among enterprises. PLIB expressed product model information with General Model, Functional Model, Functional View Model and Representation Category. It provided the capability to describe product information of multi-domain and multi-level perspective. We presented the geometry view model providing a method to build the product view representation.
