The Future of DITA

DITA (which stands for “Darwin Information Typing Architecture”) is the hottest new technology in the technical publishing market. While still early in its adoption cycle, it has the potential to become the future de facto standard for not only technical publishing, but for all serious content management and dynamic publishing applications. Whether this happens, however, will depend on the vision and creativity of the DITA standards committee, DITA vendors and DITA consultants.

While IBM originally designed DITA for technical documentation, its benefits are potentially transferable to encyclopedias, journal articles, mutual fund prospectuses, insurance policies, retail catalogs, and many, many other applications. But will it really be flexible enough to meet these other needs?

At Flatirons Solutions we’ve been testing the boundaries of DITA’s extensibility, taking DITA out of its comfort zone and thereby creating some interesting proof points for its flexibility. So far, the results are very positive. Four specific applications illustrate this:

  • User personalized documentation – designed to support a variety of enterprise content libraries out of a single set of specializations, this application involved the use of 15 conditional processing attributes to drive dynamic production of personalized documents. An initial DocBook-based prototype was later re-designed for DITA.
  • Scholarly research database – this solution involved marrying DITA with the venerable Text Encoding Initiative (TEI), a nearly 20 year old scholarly markup standard originally written in SGML. DITA was used to split the historical material into searchable topics; TEI provided the rigorous scholarly markup and annotations.
  • Dynamic web publishing – designed for a large brokerage and business services firm, this application combines a single-source DITA-based authoring environment with an optimized dynamic processing pipeline that produces highly-personalized Web pages.
  • Commercial publishing – we are currently exploring the use of DITA for encyclopedia, journal, and textbook publishing, for clients who have traditionally focused on print, but who are now also moving to increasingly sophisticated electronic products.

Of course, in pushing the boundaries we’ve also found issues. A classic example is the restriction in DITA’s “task” specialization that each step in a procedure must begin with a simple declarative statement. To make it as readable as possible, the procedure cannot begin with a statement that includes a list or multiple paragraphs or a table or a note. But what do you do if your content breaks these rules? DITA’s answer is that you rewrite your content.

Rewriting content is not unreasonable if you accept that you’re moving to DITA in order to adopt industry best practices. However, what if you don’t agree that DITA’s built-in “best practices” are the only way to write good content? Or what if you have 500,000 pages of legacy content, all of which needto be rewritten before they can conform to DITA? Would you still consider it practical?

You can solve this by making up your own “task” specialization, bypassing the constraints of the built-in “task” model. That’s an advantage of DITA. But if you do that, you’re taking a risk that you won’t be able to leverage future vendor product features based on the standard “task” specialization. And in other cases, such as limitations in handling print publishing, workarounds can be harder to find.

DITA 1.1 has made great progress toward resolving some of these issues. To be truly extensible, however, I believe that future versions of DITA will need to:

  • Add more “out-of-the-box” specialization types which DITA vendors can build into their tools (for example, generic types for commercial publishing).
  • Further generalize the existing “out-of-the-box” specialization types (for example, allowing more flexibility in procedure steps).
  • Better handle packaging of content into published books, rather than focusing primarily on Web and Help output, and adapting this model for books.
  • Simplify the means to incorporate reusable content, handle “variables” within text, and link to related content.

At conferences I’ve heard it suggested that if people don’t want to obey DITA’s particular set of rules, they should consider using another standard. I’ve even heard people say that DITA doesn’t need to focus on book publishing because print is “old school.” In my opinion, this kind of parochial thinking needs to be seriously reconsidered.

Today, DITA stands at the crossroads. If it can be aggressively generalized and extended to meet the needs of commercial publishers, catalog and promotional content, and financial services and other vertical industry applications, then it has the chance to be “the” standard in XML-based dynamic publishing. If this doesn’t happen, DITA runs the risk of being relegated to a relatively elite technical publishing standard that’s only useful if you meet its particular set of assumptions and rules.

As an industry, which way will we go?

Look ahead a bit: here, here, and here.

    I’m not sure if it’s all or nothing for DITA — the whole crossroads imagery is a little alarmist. DITA has wide (and growing) acceptance in the technical documentation arena and from where I stand that’s big enough. No, I don’t think it has to be generalized enough for the big publishing industries or die. Rather, I think it’s future lies in it’s ability to support small and quickly changing publishers who are looking for ways to get smaller amounts of procedural and technical information to readers. Right now big enterprise content management systems people seem to be adopting DITA but I’m wondering about a simple technology like blogging that allows any of us (big or small) to take content development and delivery in a different direction. Some of my ideas about the importance of integration (and not generalization) are expanded in my article about process and tools:
    But your point is a good one to bring up and discuss.
