Introduction

GB/T 16656 is a technical standard for computer interpretable expression product information and product data exchange. Its purpose is to Product Lifecycle provides an independent of any particular system, product data can describe neutral mechanism. Its function is not only suitable description for neutral file exchange, but also to achieve the foundation and sharing product databases and archiving. These categories in GB/T 16656.1 in it has been described. This part belongs to integrated resource class.

This section provides representation_schema. The model defines the structure of resources, these resources will be configured for each product data Group elements, used in various aspects of the product description, in particular the characteristics of the product. Figure 1 EXPRESS-G diagram illustrates the patterns in this section and between modes defined in the integrated resource GB/T 16656 other parts of the relationship. EXPRESS-G in GB/T 16656.11 given in Righteousness. application_context_schema, product_definition_schema, product_property_definition_schema, and product_property_representation_schema GB/T 16656.41 defined in. Pattern shown in FIG. 1 is a resource integration Constituent elements.

The revision incorporates the previous upward compatible version edits. If the following conditions are met, made to specification EXPRESS the changes are upward compatible.

--- In line with Examples GB/T 16656.21 coding, and in accordance with this section based on a previous version of GB/T 16656 application protocols, also Based on the present version of the application in line with the protocol revision.

--- Compliance with ISO 10303-22 interface, and in accordance with this section based on a previous version of GB/T 16656 application protocols, also in line with group in the present version of the application protocol revision.

--- Based on previous versions of this part of GB/T 16656 application protocol mapping table, based on the present version of the application protocol revision it is still valid.

1 Scope

This section GB/T 16656 specifies the structure of some resources, these resources will be constructed each element of product data packets used to describe production all aspects of the product, this section can be used to describe the characteristics of the product.

The following content within the scope of this section.

--- Expression related environmental norms;

--- Expression specification elements;

--- Contact element in the expression of one or more related environmental, in these related environment, and to express a concept to express elements be combined;

--- Make another expression element defines a contact element expression;

--- Make a structure involved in another expression defined two relevant expression of expression;

--- A structure of two related expression is not involved in the definition of another expression;

--- Prevent one instance of each recursive element defined constraints expression;

--- Specified by a predetermined conversion of inputs and outputs, the expression of a normative element is converted into another expression element;

--- By a predetermined conversion function, the expression of a normative element is converted into another expression element.

Beyond the scope of this part of the following.

--- Type of expression, the type of expression elements, as well as the expression of the complete specification related environmental type;

--- Expression specification purposes;

--- Contact with any possible use of the expression;

--- Between two expression to the relationship between the desired constraints;

Note. When the A to B is different from the meaning of the relationship between the significance of the relationship between B when A is between term A and term B to the presence of a relationship. Undirected relations in, A and B are equal. There can be used or the provisions of the mode of filling a predetermined pattern to EXPRESS relationship.

--- Prohibit related constraints represent a cyclic structure;

To have the desired relationship constraint --- there is a correlation between the representation of the relevant environment;

--- Prohibit the expression of the constraints of the cyclic structure among related environmental relations.
