The characteristic data model specified in ISO/TS 29002-10 is hereby incorporated by reference with the changes described in 5.2.
NOTE The rationale for these changes is as follows:
In ISO/TS 29002-10:
An organization can be identified by an organization code, or by the IRDI of a concept dictionary entry that represents the organization.
The data specification to which the catalogue data conforms can be specified, but need not be specified.
However, within ISO 22745, an organization is always referenced by its OTD-assigned IRDI, and, thus, the organization_ref attribute needs to be present in master data that complies with this part of ISO 22745. (The organization_code attribute can be present as well, if desired.) The identification guide to which the catalogue data conforms can be specified, but need not be specified. (An identification guide is a kind of data specification.)
Change the cardinality of attribute data_specification_ref from [0..1] to [1..1].
The referenced data specification shall be an identification guide that conforms to ISO/TS 22745-30.
NOTE See ISO 8000-110 for the requirement that master data reference the data specification to which it complies.
Remove attribute organization_code.
Change the cardinality of attribute organization_ref from [0..1] to [1..1].
NOTE See ISO 22745-13 for the requirement that an IRDI be assigned for each organization.
