- — the rules to group parts into leaf characterization classes of parts and non-leaf characterization classes of parts;
- — the rules for the choice of the appropriate properties to be associated with the characterization classes of parts;
- — the attributes to be provided by informationsuppliers to describe the characterization classes and properties of parts;
- — the mechanisms for connecting characterization classes of parts to classification systems;
- — the mechanisms for connecting characterization classes belonging to different characterization hierarchies;
- — the specifications of those entities and attributes in the EXPRESS information model that provide for the exchange of such dictionary data.
- — the description of any other object than part that can be characterized by a class belonging and a set of property-value pairs and to which the whole methodology defined in this part of ISO 13584 applies.
EXAMPLE
Description by means of a dictionary compliant with this part of ISO 13584 can be used for describing any kind of products, as defined in Clause 3.NOTE 1 The complete EXPRESS information model for the exchange of dictionary data, known as the common ISO13584/IEC61360 dictionary model, is defined in ISO 13584‑25. Several levels of allowed implementations for the common ISO13584/IEC61360 dictionary model, known as conformance classes, are also defined in ISO 13584‑25. Conformance class 1 consists of the various schemes documented in this part of ISO 13584 (that duplicate information contained in IEC 61360‑2), as well as the ISO13584_IEC61360_dictionary_aggregate_extension_schema documented in ISO 13584‑25 (duplicated in IEC 61360‑5 ). More advanced conformance classes, identified as conformance classes 2, 3 and 4, are documented in ISO 13584‑25.
The following are outside the scope of this part of ISO 13584:-
— properties of which values have an aggregate structure;
NOTE 2 An EXPRESS information model for the exchange of properties of which values have an aggregate structure is defined in ISO 13584‑25.
- — the description of the parts themselves;
- — the descriptions of the functional models that can refer to some class of parts;
-
— the description of tables, program libraries and documents that can refer to some class of parts;
NOTE 3 EXPRESS resource constructs for the exchange of these information elements are defined in ISO 13584‑24:2003.
- — the description of the systems intended to manage parts libraries.
- — integration in the same data repository of different parts libraries originating from different informationsuppliers with uniform access mechanism provided by a dictionary;
- — referencing another supplier library assumed to be available on the receiving system;
- — referencing a standardized characterization hierarchy when such a hierarchy exists;
- — definition by an end-user of a local categorization or search hierarchy, and the mapping of these hierarchies onto the supplier libraries available on its system.
