Robert, et al:

I'm using DocBook SGML (and could as easily be using XML) for a
home-grown help system with our web UI. We have help buttons on web
pages that use javascript to generate a pop-up window with the help
topic.

To create "help files" (really a series of HTML docs), I perform the
following general procedure:
1. Write content using a text editor. I place all DocBook markup in the
documents by hand.
2. Convert DocBook files to HTML using "jade", an SGML processing tool.
For XML, similar tools exist and go by names such as Saxon and Xalan.
3. Communicate HTML file names (hooks) to the developers so the help is
context sensitive.

I've worked with RoboHelp before and found the general procedure to be
very similar. My only problem is that DocBook has a steep learning
curve. Not a problem for me, per se, but its a problem for getting
others integrated into the help writing process. The DocBook->HTML
solution is more like development than like writing. But, the more I
think about it, I had these problems with RoboHelp...

Markup in DocBook is very rich. I can mark a word as <command> for a
command line term, write a <procedure> when needed, and give cross
references (<xref>) when the need arises.

The only thing lacking from DocBook at this point for writing help
systems is a paradigm for help topics. DocBook documents are written
with a <section> within a <chapter> within a <book>...etc. The
topic-based nature of help doesn't shoehorn in very clearly to DocBook's
current state. I wrote each help topic as a <section> within a
<chapter>. When I think about the topics, I would think it'd make more
sense to tag a help topic as <topic>.

Interestingly, on the DocBook list (docbook -at- lists -dot- oasis-open -dot- org), there
is a conversation going on right now about adding help topic tags to the
DTD. The thread is archived here:
http://lists.oasis-open.org/archives/docbook/200110/msg00082.html.

To learn more about using DocBook (available in both XML and SGML
versions) for help authoring, I'd suggest you check out the docbook and
docbook-apps mailing lists (subscription and archive info at
http://lists.oasis-open.org/archives/). Also, many Open Source
development projects are using DocBook for their help systems. Check out
GNOME Documentation Project (http://developer.gnome.org/projects/gdp/).
John Fleck at GNOME is working on a help rendering system with XML at
its core.

The DocBook approach does have a big learning curve (like learning HTML
plus learning all the document conversion/processing tools that are
somewhat tricky). If you want to stick with the Windows/GUI route, I ran
a search and noticed Webworks has XML support:
http://www.webworks.com/company/pr050800.asp.

Good luck!

Meg
