The second edition, ISO 10303-21:2002, included the corrigendum and extensions for several data sections. The third edition, ISO 10303-21:2016, added anchor, reference and signature sections to support external references, support for compressed exchange structures in a ZIP-based archive, digital signatures, and UTF-8 character encoding.

ISO 10303 is an ISO standard for the computer-interpretable representation and exchange of product manufacturing information. It is an ASCII -based format. [ 1 ] : 59 Its official title is: Automation systems and integration — Product data representation and exchange .
Part 216 - Ship moulded forms; Part 218 - Ship structures; Part 219 - Dimensional inspection information exchange; Part 221 - Functional data and their schematic representation for process plant; Part 223 - Exchange of design and manufacturing product information for cast parts, currently on CD level
ISO 10303-21: Data exchange form of STEP with an ASCII structure; ISO 10303-22: Standard data access interface, part of the implementation methods of STEP; ISO 10303-28: STEP-XML specifies the use of the Extensible Markup Language (XML) to represent EXPRESS schema; ISO 13584-24: The logical model of PLIB is specified in EXPRESS; ISO 13399: ISO ...
STEP-NC interface on a CNC, showing product shape and color-coded tolerance state. STEP-NC is a machine tool control language that extends the ISO 10303 STEP standards with the machining model in ISO 14649, [1] adding geometric dimension and tolerance data for inspection, and the STEP PDM model for integration into the wider enterprise.
ISO 10303-22 is a part of the implementation methods of STEP with the official title Standard data access interface or simply SDAI. SDAI defines an abstract Application Programming Interface (API) to work on application data according to a given data models defined in EXPRESS. SDAI itself is defined independent of a particular programming language.
The STEP ISO 10303 Application modules define common building blocks to create modular Application Protocols (AP) within ISO 10303. Higher-level modules are built up from lower-level modules. The modules on the lowest level are wrappers of concepts, defined in the Integrated Resources (IR) or Application Integrated Constructs (AIC). Modules on ...
STEP-XML specifies the use of the Extensible Markup Language to represent EXPRESS schema (ISO 10303-11) and the data that is governed by those EXPRESS schema. It is an alternative method to STEP-File for the exchange of data according to ISO 10303. The following specifications are within the scope of ISO 10303-28:
