Introduction

GB/T 20719 is a national standard for the use of computer-interpretable information exchanges related to the manufacturing process.

The GB/T 20719 standard contains all the parts that are combined to provide a language for describing the manufacturing process throughout the entire production process (The production process may be located in an industrial company, may also span several industrial sectors or companies), and independent of any particular representation of the mold type. The essence of language makes it suitable for sharing process information related to manufacturing at all stages of the production process.

This part of GB/T 20719 provides a description of the core elements of the language defined in GB/T 20719.

All parts of GB/T 20719 are independent of the representation or model of any particular process used in the software industry of manufacturing management.

All parts of this standard work together to provide a structural framework for improving the synergy of these applications.
