A STEP-file is ASCII text with the format defined in ISO 10303-21 Clear Text Encoding of the Exchange Structure. [2] ISO 10303-21 defines the encoding mechanism for representing data conforming to a particular schema in the EXPRESS data modeling language specified in ISO 10303-11. A STEP-File is also called p21-File and STEP Physical File.
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 .
STEP (ISO 10303 – STandard for the Exchange of Product model data) The work with the ISO 10303 standard was initiated in 1984 and initially published in 1994, with the objective to standardize the exchange of product data between PLM systems. It is a very comprehensive set of specifications covering many different product types and many life ...

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 ...
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.
