EXPRESS dictionary mode. " this portion of the GB/T 17564.2-2005 comparison, the main changes are as follows.

1) increasing the number of terms and definitions;

2) In the dictionary mode chapter, added "references to other dictionaries" and "dictionary identifies" two;

3) increased public dictionary "class_constraint_schema" and "item_class_case_of_schema" two chapters (ie Chapter 7 and Chapter 8);

4) delete the last version in Chapter 7, "Template";

5) A "(normative) Value Format" and Appendix.

1 Scope

This section provides a formal model of data representation in order to provide the means for the computer can recognize such data expression and exchange.

The purpose of this section is to provide a common information model of IEC/SC3D and ISO TC184/SC4 work in order to achieve the system dictionary System is able to meet the two technical committees handling standard data.

The scope of this section is based on the public GB/T 17564.1 and two basic standard range of the associated portion formed to develop ISO 13584-42 Total ISO/IEC dictionary mode.

EXPRESS model gives the two common forms of standard model and to facilitate coordination of the two standards.

GB/T 17564.2 is the primary standard, ISO 13584-42 adopted GB/T 17564.2 informative appendix EXPRESS model.

In some, by independent public EXPRESS model allows to define, GB/T 17564.1 methodology section defines the autonomous definition limit.

This section applies to the dictionary definition of the system to achieve two optional selectable modes. Each selectable mode is called consistency classes.

--- ISO 13584_IEC 61360_dictionary_schema2 predetermined data element type definitions associated with the use of classification model Technical data element types of modeling and exchange, the model constitutes consistency class IEC 61360 Part 1.

--- ISO 13584_IEC 61360_language_resource_schema provide resources to allow different language strings. due to it is extracted from the dictionary mode, so it can be used in other modes. It is largely based on ISO 10303-41:2000 the support_resource_schema basis, it can be seen as an extension. When using a multi-language, allowing the entire exchange Context (physical file) in a non-specific language often quoted.

When and GB/T 16656.21 used together, each mode defines a single exchange format.

Class 1 conformance interchange format is fully compatible with the GB/T 17645 series of standards.
