The DocBook Assembly document type was introduced with DocBook 5.1 and it is used to define the hierarchy and relationships for a collection of resources. It is especially helpful for topic-oriented authoring scenarios since it assembles a set of resources (such as DocBook 5.1 topics) to form a hierarchical structure for a larger publication.

An Assembly document usually has four major parts:
  • Resources - Identifies a collection of resources (such as topics). An Assembly may identify one or more collections.
  • Structure - Identifies an artifact to be assembled. A document in this case is the particular collection of resources (such as topics) that forms the documentation. Within the structure element, an output element can be used to identify the type of output to be generated and module elements can be used to identify the resources to be included. An Assembly may identify one or more structures.
  • Relationships - Identifies relationships between resources. These relationships may be manifested in any number of structures during assembly. An Assembly may identify any number of relationships.
  • Transformations - Identifies transformations that can be applied during assembly. An Assembly may identify any number of transformations.

For detailed information about the DocBook Assembly document type, see DocBook 5.1: The Definitive Guide - DocBook Assemblies.

File Definition

A file is considered to be an Assembly when the root name is assembly.

Default Document Templates

A default Assembly document template is available when creating new documents from templates and it can be found in: Framework Templates > DocBook 5 > DocBook 5.1.

The default template for DocBook Assembly documents is located in the [OXYGEN_INSTALL_DIR]/frameworks/docbook/templates/Docbook5.1 folder.

Default Schema for Validation and Content Completion

The default schema that is used if one is not detected is docbookxi.rng and it is stored in [OXYGEN_INSTALL_DIR]/frameworks/docbook/5.1/rng/.

Transformation Scenarios

Oxygen XML Editor includes a built-in transformation scenario that can be applied on an Assembly file to generate an assembled (merged) DocBook file. The scenario is called DocBook Assembly and is found in the DocBook 5 section in the Configure Transformation Scenario(s) dialog box.
