Abstract:

STEP has provided an architecture and methods for the development of application protocols (APs). An AP is a standards document (a part of ISO 10303) that provides for communication of information in a well defined application context. The use of an AP ensures that the information conveyed is that which was intended. It also ensures that the information conveyed is adequate for specific uses of product data identified as the purpose of the AP. This report presents a tutorial for the development and use of APs using the architecture and methods of STEP. It provides definitions, rationales, and examples of the principle components of the STEP architecture as well as their use for a sample population. The sample population is presented using both clear text endoding and an example relational database implementation. The presented definitions, rationales, and example AP provide a foundation for a strategy to develop and use interrelated application protocols (IAPs).
