scope:

This part of ISO 13584 specifies generic EXPRESS resource constructs that support the description of different kinds of information about supplier libraries. It also contains a set of integrated EXPRESS information models for representing supplier libraries for the purpose of exchange. These integrated information models integrate EXPRESS resource constructs from different parts of ISO 13584 and ISO 10303 into a single schema. Supplier libraries may consist of definitions or representations of families of parts. Supplier libraries may also define new representation categories. Supplier libraries may consist only of dictionary elements, or they may also contain specifications of permitted instances. When used together with view exchange protocols, these integrated information models also permit the exchange of one or several representation categories for the parts defined in a parts library.
