4.2.172 Document_file_relationship

A Document_file_relationship is a relationship between two Document_file objects. It specifies that the related Document_file is referenced from the relating Document_file.

EXAMPLE A service manual may contain graphics for explanatory reasons. In this case the Document_file objects that contain the graphics are referenced as related from the Document_file object that contains the body of the service manual with relation_type 'reference'.

The data associated with a Document_file_relationship are the following:

4.2.172.1 description

The description specifies additional information about the Document_file_relationship.

See document_file_relationship to multi_language_string for the application assertion.

The description need not be specified for a particular Document_file_relationship.

If present, there shall be exactly one object that defines the description for a Document_file_relationship.

4.2.172.2 related

The related specifies the second of the two objects related by the Document_file_relationship.

NOTE The semantics of this attribute are defined by the attribute relation_type.

See document_file_relationship to document_file for the application assertion.

4.2.172.3 relating

The relating specifies the first of the two objects related by the Document_file_relationship.

NOTE The semantics of this attribute are defined by the attribute relation_type.

See document_file_relationship to document_file for the application assertion.

4.2.172.4 relation_type

The relation_type specifies the meaning of the relationship. The values 'addition', 'decomposition', and 'peer' are only allowed if neither the relating nor the related Document_file are included in a Document_representation.

Where applicable the following values shall be used:

The values 'addition', 'decomposition', and 'peer' are used for the purpose of creating logical structures of documents. These values shall only be used for the relation_type of Document_file_relationship, if the referenced Document_file objects do not participate in a Document_representation. In the latter case, Document_structure shall be used instead.
