Industrial automation systems and integration -- Parts library -- Part 25: Logical resource: Logical model of supplier library with aggregate values and explicit content
détails du produit
When used together with view exchange protocols, this integrated information model also permits the exchange of one or several representation categories for the parts defined in a parts library.
The following are within the scope of ISO 13584-25:2004:
- generic resource constructs for representing aggregate data types. Aggregate data types and values are modelled 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 assembled parts that may contain an unlimited number of constituent components;
- a library integrated information model that provides for modelling and exchanging supplier libraries that contain properties whose values may be aggregate-structured, and whose possible class extensions are explicitly described as sets of instances.
The following are outside the scope of this part of ISO 13584-25:2004:
- 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 the information models defined in ISO 13584-25:2004.
