Wikipedia article on STEP
General information about STEP that is of encyclopedic interest.
WikiSTEP
Tutorials and detailed information about STEP and recommended practices on how best to implement STEP.
Recommended Practices for the Use of STEP Application Protocols
This site, maintained by the PDES, Inc. consortium, hosts the recommended practices documents for several STEP Application Modules. These documents are agreements among the implementers of STEP, and provide valuable insight on the meaning and intended use of the Application Protocols, beyond the information contained in the ISO 10303-xxx standard documents themselves.
