Scope
This part of GB/T 17645 specifies the general EXPRESS resource structure, which is used to describe the aggregate data types and values that appear in the supplier library. For exchange, this part also includes the EXPRESS integration information model expressing the provider library. This integrated information model integrates the above resource structure, other parts of GB/T 17645 and other EXPRESS resource structures in GB/T 16656 into a single model. Suppliers can consist of definitions and representations of part families. They may also allow explicit specification of instance sets. When used with the view exchange protocol, the integrated information model also allows one or several parts representation classes defined in the parts library to be exchanged. The following applies to this standard: a) Generic resource constructs for expressing aggregated data types. According to the definition of aggregate data type in EXPRESS language (GB/T 16656.11), model the aggregate data type and value. b) Generic resource constructs for expressing aggregated values. c) Generic resource constructs to express assemblies (which can include an unlimited number of components). d) A library integration information model for modeling and exchanging vendor libraries (including properties whose values can be aggregated and whose possible class extensions can be explicitly described as sets of instances). The following do not apply to this standard: a) the representation of expressions and variables; b) the implicit description of the set of allowed instances of a class through constraints; c) the ability to manage supplier libraries (expressed in accordance with the information model defined in this standard) Software system requirements.
