5 Characteristic data model

5.1 General

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:

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.)

5.2 Modifications to existing entities

5.2.1 item

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.

5.2.2 reference

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.
