Application module:
Multi linguism |

This clause specifies the information requirements for the
Multi linguism
application module. The information requirements are specified as the
Application Reference Model (ARM) of this application module.
NOTE 1 A graphical representation of the information
requirements is given in
Annex C.
NOTE 2 The mapping specification is specified in
5.1. It shows how
the information requirements are met by using common resources and
constructs defined or imported in the MIM schema of this application
module.
This clause defines the information requirements to which implementations shall
conform using the EXPRESS language as defined in ISO 10303-11.
The following begins the
Multi linguism schema.
EXPRESS specification:
*)
SCHEMA Multi_linguism_arm;
(*
This subclause specifies the ARM type
for this application module. The ARM type and
definition is specified below.
The string_select type is an
extensible list of alternate data types.
Additional alternate data types are specified in select data
types that extend the
string_select type.
NOTE
This empty extensible select requires
extension in a further module to ensure that entities that refer to it have
at least one valid instantiation.
EXPRESS specification:
*)
TYPE
string_select =
EXTENSIBLE
GENERIC_ENTITY
SELECT;
END_TYPE;
(*
This subclause specifies the ARM entities for this
module. Each ARM application entity is an atomic element that
embodies a unique application concept and contains attributes
specifying the data elements of the entity. The ARM
entities and definitions are specified below.
A Language is the identification of a language by its code as defined in ISO 639-2 and possibly its country code as specified in ISO
3166-1.
EXPRESS specification:
*)
ENTITY Language;
language_code : STRING;
country_code :
OPTIONAL
STRING;
UNIQUE
UR1: language_code;
END_ENTITY;
(*
Attribute definitions:
language_code:
the string that specifies the identifier of the Language in the
Alpha-3 bibliographic code of ISO 639-2.
EXAMPLE 1
'eng' for English, 'fre' for French, 'rus' for Russian, or 'ger' for German are examples of language_code.
country_code:
the string that specifies the identifier of the country according to the alpha-2 code of ISO 3166-1.
The value of this attribute need not be specified.
EXAMPLE 2
'GB' for the United Kingdom or 'US' for the United States of America are examples of country_code.
Formal propositions:
UR1:
A Language shall only be specified once.
A Language_indication is the identification of the Language in which a text attribute of one or more instances has been specified.
NOTE
The Language_indication entity data type identifies the primary language of a text attribute while the Attribute_translation_assignment entity data type enables to
convey the translations of that attribute in various languages.
EXPRESS specification:
*)
ENTITY Language_indication;
considered_instance : string_select;
considered_attribute : STRING;
used_language : Language;
END_ENTITY;
(*
Attribute definitions:
considered_instance:
the instance for which the Language of the considered_attribute has been identified.
considered_attribute:
the name of the attribute the Language of which has been identified.
used_language:
the Language used to write the text attribute of the considered_instance.
An Attribute_translation_assignment is the assignment of a translation to a text attribute of an instance.
EXPRESS specification:
*)
ENTITY Attribute_translation_assignment;
considered_instance : string_select;
considered_attribute : STRING;
translation_text : STRING;
translation_language : Language;
UNIQUE
UR1: considered_instance, considered_attribute, translation_language;
END_ENTITY;
(*
Attribute definitions:
considered_instance:
the instance for which a translation is specified for the considered_attribute in the indicated language.
considered_attribute:
the name of the attribute for which a translation is provided.
translation_text:
the text string that specifies the translation in an additional language.
translation_language:
the Language in which the translation is provided.
Formal propositions:
UR1:
For any text-based attribute of an instance, there shall only be one translation of that attribute in a given language,
where the language is represented by
translation_language,
the attribute is represented by
considered_attribute
and the instance, by
considered_instance.
