Hi devs,
I'd like to propose forking wikimodel (http://code.google.com/p/wikimodel/) and
move its source code into our code base in XWiki Rendering as a separate module
for now.
Motivation
========
* Wikimodel has been inactive for years (since 2009). Actually that's not quite
true, there's been one developer working on it regularly, it's Thomas Mortagne…
* We heavily depend on wikimodel in the XWiki Rendering module (for our syntax
parsers) which is a key module for XWiki
* It's more difficult for us to contribute to the wikimodel project since it
means:
** committing in a different project with different rules
** there's nobody doing releases on the wikimodel projet and we need the
releases to be synced with our releases since otherwise we cannot release on a
SNAPSHOT dependency
** there's no community there so it's not fun and doesn't help for quality
control/reviews/etc
** since we push XWiki Commons and XWiki Rendering to Maven Central we also
need the wikimodel releases to be pushed to Central which is not happening now
* The wikimodel project has a different scope than our need. Mikhail (owner and
admin of Wikiodel - not active since 2009 - some commits here and there) wanted
it to remain only for wiki syntaxes. We added support for HTML parsing in it
but Mikhail never liked it and wanted us to move it to XWiki.
* We have some impedance mistmatch between the wikimodel model and the xwiki
rendering model which causes us to do some circumvolution in the code which
leads to issues still beeing open in our JIRA (they've been opened for a long
time now)
* We believe wikimodel would benefit from a larger and active community within
the XWiki ecosystem. Wikimodel has been stagnating for years and we'd like it
to live on and evolve.
Action Plan
=========
Thus Thomas and me are proposing to do the following:
* Move the sources in a new rendering module as is and use it as a library
(same as now except we rename the module name and release it under the XWiki
umbrella).
* Modify all header to put our LGPL headers everywhere
* We keep the attribution as is recommended by the ASL (see
http://www.apache.org/foundation/license-faq.html#Distribute-changes) by adding
a comment to all sources explaining where the source come from and in which
license it was and who authored the initial code and how XWiki committers have
participated to the wikimodel project. We also put that information in the
NOTICE file.
* We modify the source code slowly over time to integrate it cleanly without
our code and remove the hacks we had to do, and we bring improvements
* We post a mail on the wikimodel mailing list explaining all this and inviting
the current wikimodel committers to become committers on the xwiki rendering
module (provided they agree to follow our dev rules). We also explain how
contributors can contribute (link to jira, link to github for pull requests,
etc)
+1.
What name will it have? It can't have the exact name as before, but it
would be OK to just prefix it, like xwiki-rendering-wikimodel or something.
An estimated timeline? Do you want to do this in 3.5 or 4.0?
Do we remove code that we don't use? For example, will we keep both WEM
and WOM?
Related question (not part of the vote)
=============================
* We could decide to move XWiki Commons and XWiki Rendering under the ASL since
they're libraries and as libraries the ASL is the license that makes it the
easier possible to use from all other licenses. Right now ASL code cannot use
our Rendering module because we're LGPL.
Here's my +1 to this plan.
I'm also currently +1 to brainstorm about moving XWiki Commons and XWiki
Rendering to the ASL.
Thanks
-Vincent
