ISO 10303-21:2002 Industrial automation systems and integration - Product data representation and exchange - Part 21: Implementation methods: Clear text encoding of the exchange structure
This part of ISO 10303 specifies an exchange structure format using a clear text encoding of product data for which the conceptual model is specified in the EXPRESS language (ISO 10303-11). The exchange format is suitable for the transfer of product data among computer systems.
The mapping from the EXPRESS language to the syntax of the exchange structure is specified. Any EXPRESS schema can be mapped onto the exchange structure syntax.
