适用范围：This part of ISO 13584 provides generic EXPRESS resource constructs that support the description ofaggregate data types and values occurring in supplier libraries. It also contains an integrated EXPRESSinformation model for representing supplier libraries for the purpose of exchange. This integratedinformation model integrates the above resource constructs with other EXPRESS resource constructsfrom different parts of ISO 13584 and ISO 10303 into one single schema. Supplier libraries may consistof definitions and of representations of families of parts. They may also define new representationcategories. Supplier libraries may consist only of dictionary elements with or without aggregate datatypes, or they may also contain explicit specifications of the sets of permitted instances.When used together with view exchange protocols, this integrated information model also permits theexchange of one or several representation categories for the parts defined in a parts library.The following are within the scope of this part of ISO 13584:— generic resource constructs for representing aggregate data types. Aggregate data types andvalues are modeled according to the definition of aggregate data types of the EXPRESS language(ISO 10303-11);— generic resource constructs for representing aggregate values;— generic resource constructs for representing of assembled parts that may contain an unlimitednumber of constituent components;— a library integrated information model that provides for modeling and exchanging supplier librariesthat contain properties whose values may be aggregate-structured, and whose possible classextensions are explicitly described as sets of instances.The following are outside the scope of this part of ISO 13584:— representation of expressions and variables;— implicit description of the set of permitted instances of a class by means of constraints;— specification of a software system able to manage supplier libraries represented according to theinformation models defined in this part of ISO 13584.
