5 Terminology Service data model

5.1 General

The Terminology Service data model specified in ISO/TS 29002-20 is hereby incorporated by reference with the changes described in 5.2.

NOTE   The rationale for these changes is as follows:

In ISO/TS 29002-20, a language can be identified by an ISO language code and, optionally, an ISO country code; or by the IRDI of a concept dictionary entry that represents the language. However, within ISO 22745, a language is always referenced by its OTD-assigned IRDI, and, thus, the code attribute cannot be present in input or output to a service that complies with this part of ISO 22745.

5.2 Modifications to existing entities

5.2.1 concept_search_specification

Change the cardinality of attribute language_code from [0..1] to [0..0].

Change the cardinality of attribute country_code from [0..1] to [0..0].

Change the cardinality of attribute language_ref from [0..1] to [1..1].

NOTE   See ISO 22745-13 for the requirement that an IRDI be assigned for each language.
