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 .
The ISO 10303 STEP standards also handle a wide range of PMI information. 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 ...
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 standard for cutting tool data representation and exchange
For example, IUPAC has, since 1982, defined standard reference conditions as being 0 °C and 100 kPa (1 bar), in contrast to its old standard of 0 °C and 101.325 kPa (1 atm). [2] The new value is the mean atmospheric pressure at an altitude of about 112 metres, which is closer to the worldwide median altitude of human habitation (194 m). [10]

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:
