ISO 10303 STEP product-data exchange architecture

Document status: reviewed. Canonical source.

Summary

STEP is a family of product-information representation and exchange standards designed to survive exchange among heterogeneous systems across a product lifecycle, with explicit data specification methods and modular parts.

NUIF relevance

The lesson is organizational: a durable interchange specification needs modular normative parts, conformance classes and schema discipline. Avoid STEP’s complexity explosion by aggressively constraining the NUIF core and using profiles/extensions.
