You are underestimate the efforts.

We can make a shout match out of this ("No, I don't" ;-) - but I'd
prefer to use the time more productive.

I still think using the wiki wouldn't be too hard (with some creative
template usage), but I also like your idea of using a WYSIWYG XML

After googling around a bit (see linklist at the end of this mail) I
still tend to using the wiki because there are some (at least at the
first look) working converters available, while using bitflux would
maybe cause more work - it looks like the editor is only the frontend,
and the server-side handling would need to be written.

Another advantage of using the wiki as base would be that we can easily
create an "offline copy" of the wiki (for regions without useable
internet access) or of a set of pages (for example a build service
</written after otherwise completing the mail>

90% of the formatting can be done with plain wikitext, and for the
remaining 10% templates can be used (which can, but don't have to
have a visible effect in the wiki). A "visible" template might be
something like "text printed on screen", an "invisible" template
might contain a keyword for the book index.

We use a feature in DocBook/Novdoc what is called "profiling". We
label one paragraph for business related products and another one
for openSUSE products. When we process the manual, the paragraphs
are being "filtered" so only the requested product is visible in the
end format. Maybe this belongs to the remaining 10%...

That could use something like

{{only_openSUSE|paragraph text}} or {{only_SLES|paragraph text}}

and the template would just be {{{1}}} to show the text and empty to
hide it.

Or, to make it a bit more flexible and to allow multiple targets without
duplicating the content, something like {{onlyIn|SLES,SLED|text}} could
be used in combination with ParserFunctions.

I think we could even develop a "XML skin" for mediawiki so that
the wiki can generate valid docbook/novdoc XML out of wiki pages
(with <para> instead of <p> etc.).
The alternative solution would be to post-process the wikitext or
the HTML to convert it to XML.

Depending on the HTML this sounds scaring.

The advantage of the wiki is that it is _generated_ HTML (from
wikitext), so it won't be too scary ;-)

I'm afraid that the learning curve is too high - lessons for
lizards unfortunately gave you/us that lesson...

Sorry, but I never understood the "XML is too difficult" rant. People
are *not* afraid to learn LaTeX or Wiki, dig into HTML, or even
migrate from Windows to Linux because of "the learning curve is too
high". Why they are not afraid? Because they are _interested_ and
want to _learn_ something new.

Or because they need it (for private usage or for the job) and _have to_
learn it.

Why should it be difficult to learn DocBook/Novdoc? It's just a
format as HTML, WikiText, ASCIIDoc, or anything else. Maybe it's a
bit more verbose, but if you can write HTML and design your webpage,
you can also write documentation in DocBook or Novdoc. It's just a
matter of your XML editor.

I think we should "split" the potential editors in two groups:

a) people that want to do large contributions, for example a new
chapter about <insert topic here>

They will probably have no problem with learning the needed XML, and
they'll probably also fit your "want to learn something new".
Even if they initially didn't want to learn XML, the effort is small
compared to writing all the text, and therefore acceptable.

b) people that "just" want to fix a small error or a typo

I doubt that they will happily learn XML "just" to fix a typo or mark
a link as a link - the effort to result quotient is too bad in this
case ;-)
For those people, having an "Edit" link in the online version of the
manual would be a very big advantage.

I don't know if the learning curve was the only problem there, but
at least it's "I have to learn another thing before I can

I'm afraid, I have to disagree here. "To learn another thing before I
can contribute" is the case for _every_ open source project. If you
want to contribute, you usually use what's there. If you are
interested enough then you are willing to take that "extra step".
If not, you simply don't contribute.

Thanks for confirming my two groups from above ;-) but I'd prefer not to
have that "extra step" so that everybody can contribute.

Just think of this example: People were not afraid to learn CVS.
After some time, it was more or less replaced by Subversion.
Although it was not that different, people were willing to learn the

I think many users could just do
alias cvs=svn
and continue as usual ;-) because the features most people use (co, up,
diff, commit) are basically the same.

Now it seems Git will be the sucessor for Subversion.
And *that* is really different from CVS/Subversion! And what's the
opinion? "Git is soo coool!" is what can I heare a lot. ;)

Again, this depends on your usage and needs. I know that Git has lots of
features, but IMHO that makes it also complicated when compared to SVN.

Personally I'd say I know SVN quite well, but don't really know Git
because I didn't really need it until now. The good thing is that at
least the checkout/clone is quite easy (and copy&paste-ready available
on most project homepages) - without knowing all details of Git, I can
still send a patch or post it in the bugtracker.

Developers who use Git in their daily work will of course know it better
and just ask the upstream developers to pick their changes from their
private Git repo.

Back to the manual: the question is if we need another tool which every
contributor has to learn (XML), or if we can use an existing one (wiki).

Let me suggest another idea:
In my opinion, most people have problems with XML because it's (a)
too verbose, (b) it's too "complicated", and (c) you don't see the
result. At least that's what I hear a lot.

Yes, that sums up the problem quite good.

As most of the functionality thesedays goes through the Web, why not
have a XML editor in, let's say, Firefox?

Of course, it should offer the usual features but would hide the XML
syntax and display just the rendered text. I know, this is
day-dreaming and the idea is not new. However, I think, this would
lower the entrance. We could use the existing XML source without
converting it to Wiki while embracing Web usability. I think, this
should solve the above problems.

Indeed, this sounds like a very good idea.

Since we are already dreaming: the HTML version of the manual should
have an "[Edit]" link attached to every section ;-)

We would also need an easy way to create a new chapter, but that has
lower priority because it isn't needed too often compared to fixing
errors or adding some details in the existing chapters.

If it works as expected, it would be a good solution that would make
contribution easy (that's the main problem with the current manuals).

Maybe we could use Bitflux, see

The description on the homepage looks promising. Unfortunately the demo
seems to be broken (lots of "not found" errors for the JS files)...

I see the public SVN as a fast solution so that people have a
chance to dig into the manual's source. It might even be read-only
in the beginning - having to upload patches to bugzilla or send
them to the -doc mailinglist is still easier than reporting "on
page 123 in section 'foo', there's a typo in 'baar'".

A page number is a bad choice as it can change easily. Better use the
section title or an anchor from HTML. :)

I was more thinking of PDF or printed manuals in this case ;-)

BTW: I think Jana Jaeger can tell you a story about printed manuals and
paperclips. hint: bug 65000 *g*

You have to "switch" from the rendered manual (HTML, PDF, ...) to
the XML source, and you have to know at least some XML basics.

In Wikis you have to know some Wiki basics. What's the point here? :)

I see several points:
- the wiki has a "preview" button where you can see your changes. That's
not WYSIWYG, but not too far away
- lots of people know wiki basics (think of all the people that write in
- and even if you don't know wiki syntax, I'd say it is very easy to
understand - for example, a paragraph is just, well, a paragraph.

More important (and missed in your question) is the "switch" from the
rendered manual to XML source. Finding the correct place to edit in the
XML can be more difficult than doing the actual text change.
That's where the wiki is really good with an "[Edit]" link at every

OTOH the wiki is more like a long(er)-term solution, but makes
contribution much easier - just click "Edit".
Although I'm not that much into the Wiki topic, I have the impression
the Wiki syntax is not very well "established": One Wiki supports a
certain syntax, another don't. If this is really the case, I
wouldn't call Wikis "a long-term solution".

Yes, there is indeed some wiki software with slightly different syntax.
I don't really see a problem in that because the software we use
(Mediawiki) has a well-defined syntax and is broadly used (wikipedia).

BTW: HTML and CSS have a similar "problem" - some browsers understand
additional tags or even misinterpret some tags. Does this mean nobody
uses HTML? ;-)

For easier contribution: See my idea above.

Indeed, an online editor for the manual would be a very good idea.

The main reasons why I proposed using the wiki are:
- the "[Edit]" link - that makes finding the correct place for an edit
easy (no need for grep, searching in the file etc.)
- already well-known or at least very easy to learn syntax
- result visible instantly

When I wrote my proposal, I wasn't aware of Bitflux, and therefore the
wiki was the tool that fulfilled the above requirements best.
If Bitflux can do all that and additionally keep the XML format, then it
might even be better than using the wiki.

Yes, writing a good wiki-to-XML tool will need some work, but it is
possible. And it is worth the effort IMHO.

Why should we write some wiki-to-XML converter when we have already
everything in place, ready to be used?

To make it easier for contributors. But see above...

Let me paste some links that might be useful for the discussion and/or
technical implementation. Note that I just had a quick look at the
following pages. and
overview on several tools for wiki -> docbook
(seems openSUSE is not the only project that has a need for this)
looks like working code, page mentions "partial working", so the
converter might need finetuning
Mediawiki extensions for docbook export
online converter for wikitext -> docbook (and other formats), source
a wiki working with docbook format internally
command-line wikitext -> docbook converter

And now to the fun part:

You compare apples with oranges. :)

Why not? Both are round, and you can eat both of them ;-))
