4.2.177 Document_structure
A Document_structure is a relationship between two Document_representation objects.
The data associated with a Document_structure are the following:
- description;
- related;
- relating;
- relation_type.
4.2.177.1 description
The description specifies additional information about the Document_structure.
See document_structure to multi_language_string for the application assertion.
The description need not be specified for a particular Document_structure.
If present, there shall be exactly one object that defines the description for a Document_structure.
4.2.177.2 related
The related specifies the second of the two objects related by the Document_structure.
NOTE The semantics of this attribute are defined by the attribute relation_type.
See document_structure to document_representation for the application assertion.
4.2.177.3 relating
The relating specifies the first of the two objects related by the Document_structure.
NOTE The semantics of this attribute are defined by the attribute relation_type.
See document_structure to document_representation for the application assertion.
4.2.177.4 relation_type
The relation_type specifies the meaning of the relationship.
Where applicable the following values shall be used:
- 'addition': The application object specifies that the related document provides supplementary or collateral information with regard to the information provided by the relating document;
- 'copy': The application object defines a relationship where the related Document_representation is a copy of the relating Document_representation;
- 'decomposition': The application object defines a relationship where the related Document_representation is one of potentially more sub documents of the relating Document_representation;
EXAMPLE The decomposition of a document into clauses is an example for the use of this value.
- 'derivation': The application object defines a relationship where the related Document_representation is derived from the relating Document_representation;
EXAMPLE A raster image may be derived from a 3D CAD model.
EXAMPLE A html version may be derived from a text document as an alternative.
- 'peer': The application object specifies that the related document provides required information with regard to that provided by the relating document. The peer document is essential for a complete understanding;
- 'reference': The application object defines a relationship where the related document is referenced from the relating;
EXAMPLE A hyperlink is an example for a 'reference'.
- 'sequence': The application object defines a logical sequence where the related Document_representation comes after the relating Document_representation;
EXAMPLE A sequence of clauses.
- 'substitution': The application object defines a relationship where the related Document_representation replaces the relating Document_representation;
- 'translation': The Document_structure specifies that the related document is generated through a translation process from the relating document.
