Based on those notes, and giving things more thought, here are a
couple of other ideas.
How would people feel about keeping document structures as they are
now (each flavor has its own, complete branch), but identify in the
wiki which components are shared between which versions? Then, during
earlier parts of the documentation cycle, all doc-team members
(regardless of the particular flavor they usually contribute to) would
work primarily on the shared documentation (e.g., basic-commands,
advanced-topics, add-applications, administrative, etc.) in the
official Ubuntu branch repository.
As the cycle draws to a close, documentation team members who
primarily work on other another flavor of Ubuntu could extract the
common documentation topics from the Ubuntu docs, and apply them to
their flavor's branches. For example, I would copy out the "internet"
section from Ubuntu and apply it to Xubuntu. From there, it would
only require a few tweaks to suit Xubuntu. (I think that this
approach might not benefit Kubuntu quite as much, as their docs are
oftentimes quite different.)
I think this would be better than doing a lot of merges to stay up to
date. The above approach would allow people to spend more of their
time focusing on their flavor-specific elements in their own
repository, and bring over the close-to-complete documents from Ubuntu
toward the very end of the cycle. They would then just have to modify
a little content and (perhaps - see below...) the linking structures
to suit their flavor (i.e., remove all of the ghelp links and replace
them with xrefs, ulinks, or kde-style links).

Agreed. I didn't really think of the bzr speed issue. Bzr has gotten
a bit better, but it's still not lightning-fast with larger branches.

That's a good point, too.

Right. The person who I saw speak on this at the conference did
comment about how architecting content for reuse in this way affects
(and in some ways, constricts) how you are able to phrase things.
As Jim pointed out, linking would also

Changing our approach to linking may be helpful, I think. What if we
used entities to handle all of our links? If we store all of our links
in entities we could reduce the amount of time that we spend typing
links, reduce the opportunities for incorrectly-formatted links in the
documentation, and make it easier to update the links of URL's that no
longer work due to changes on the internet (if we update the link from
the entity once, and all applicable links would be updated).
This could also make it a lot easier to accommodate links across
flavors. It wouldn't matter that Ubuntu uses ghelp links and Xubuntu
doesn't... we would just have to use different entity files, and note
that a different entity file is being used in the top-portions of our
I know that yelp uses the actual xml files - would using entities
instead of the actual ghelp links break things in yelp at all?

Merging is easy but sometimes the changes can come in
fast-and-furious, so it can be hard to keep up sometimes. Also, even
though merging is quite easy when there are no conflicts, it can eat
up time when having to resolve conflicts, especially where it is not
immediately clear where there are differences. This isn't a huge
issue, it's just time that could be better spent documenting other
stuff (or eating or sleeping, etc.)

If people have other ideas, feel free to share. Thanks,
