16 Language schema

16.1 General

The subject of the language_schema specifies the data structure for the representation of language support. This clause defines the information requirements to which implementations shall conform using the EXPRESS language as defined in ISO 10303-11. The following EXPRESS declaration begins the language_schema and identifies the necessary external references.

Each implementation of an AP that uses this schema and that encodes entity names shall use the encoding specified in Annex A. Each reference to this schema in an open system shall use the identifier encoding specified in Annex B. This schema is illustrated in Annex D using the EXPRESS-G notation.

EXPRESS specification:

*)
SCHEMA language_schema;

REFERENCE FROM group_schema    --  ISO 10303-41
  (group);
(*

NOTE 1   The schemas referenced above are specified in the following parts:

group_schema ISO 10303-41

NOTE 2   See Annex D for a graphical representation of this schema.

16.2 Fundamental concepts and assumptions

This specifies the representation of the language used in text attributes and the association of translations to these texts.

16.3 language_schema entity definition

16.3.1 language   EXPRESS-G

A language is a type of group that is a specification of the language in which an information is given. The group shall specify in its name a language code according to ISO 639-2, and, if present, in its description a country code according to ISO 3166-1.

EXPRESS specification:

*)
ENTITY language
  SUBTYPE OF (group);
WHERE
  WR1: SELF\group.name <> '';
END_ENTITY;
(*

Formal propositions:

WR1: The name attribute of the language shall be specified.
