Application Summary AI generated
This standard defines the EXPRESS language, a formal data specification language used to describe product data models within the STEP framework. It is applied in industrial automation and integration contexts, enabling engineers and software developers to create unambiguous, computer-interpretable definitions of product information for exchange across different CAD, CAM, and PDM systems. The reference manual serves as the authoritative guide for implementing EXPRESS in data modeling and system interoperability testing.
