Abstract

ISO 10303 specifies a language by which aspects of product data can be defined. The language is called EXPRESS. ISO 10303-11:2004 also specifies a graphical representation for a subset of the constructs in the EXPRESS language. This graphical representation is called EXPRESS-G. EXPRESS is a data specification language as defined in ISO 10303-1. It consists of language elements that allow an unambiguous data definition and specification of constraints on the data defined.

The following are within the scope of ISO 10303-11:2004:

  • data types;
  • constraints on instances of the data types.

The following are outside the scope of this part of ISO 10303:

  • definition of database formats;
  • definition of file formats;
  • definition of transfer formats;
  • process control;
  • information processing;
  • exception handling.

EXPRESS is not a programming language.
