With the introduction of DocBook V5.0, there have been several new initiatives started to take advantage of the increased flexibility and customizability of the standard. Two of these initiatives have become subcommittees of the OASIS DocBook Technical Committee:
- OASIS DocBook Publisher’s Subcommittee
This subcommittee is chartered to develop and maintain official variants of DocBook in support of the publishing industry. In May, 2009, this subcommittee released The DocBook Publishers Schema Version 1.0, a draft based on the DocBook V5.0 standard.
- OASIS DocBook eLearning Subcommittee
This subcommittee will develop enhancements to the DocBook standard for eLearning applications, including materials for online learning, instructor-led training and other related educational activities.
In addition to these two subcommittees, there is a current effort to create markup for an “assembly” capability to better support development of documents using a modular approach.
Most modular methodologies use a topic-oriented approach, where writers create independent units of information that are meant to stand alone. Topics are then collected into a library in much the same way that programmers create libraries of functions. Authors select the topics they need to assemble the documentation for a particular system from the library.
In order to support modular methodologies, you need support for marking up individual topics, which DocBook does well. You also need support for some kind of “map” or “assembly” file that identifies which topics are required for a particular deliverable, and at least for print deliverables, what order they should be presented in.
The proposed DocBook assembly would serve this purpose. While still under consideration as this book is being written, the general outline of an assembly is clear. It would identify a collection of resources (which could include topics and other modules), an ordering of those resources for a particular document, a set of relationships between resources, and the transformations that are to be applied to the collection.
While DocBook already supports many aspects of topic-oriented writing, the assembly mechanism is being designed to provide a more capable and intuitive model for this type of methodology.
