17. 11/17/15 OW2 con' 2015
Community

18. 11/17/15 OW2 con' 2015
Governance
● XWiki.org is an Open Source project
● LGPL license
● Driven by its community

19. 11/17/15 OW2 con' 2015
The community
● As many open source projects, our
community gets together on the mailing
lists.
● There are 3 active lists, recently
accumulating 95 messages per day
● 2 main lists:
● «users» where users get help from the team
● «dev» where developers discuss new
features, technical issues, etc...

20. 11/17/15 OW2 con' 2015
«Committer»
● A developer who have the right to push
commits on the official repository
● But being a «committer» involves more:
● Right to vote (when new features are
proposed, when some important changes are
going to be made)
– It's actually a duty.
● A veto: a committer can «block» a proposal
(but he needs to have good reasons)

21. 11/17/15 OW2 con' 2015
Committer
● A committer has also priviligied access to
the infra (bug tracker, official website, ci
server, github administration, etc...)
● Duty to perform releases (at least one
per year)
● Duty to watch everything that happens
in the repository and verify its quality.

22. 11/17/15 OW2 con' 2015
Committer
● Duty to look at contributions (Pull
Requests, etc...) and apply them if
possible
● More generally, discuss about the
direction of the project
● And more...
● See:

ommittership

23. 11/17/15 OW2 con' 2015
Committership
● Important: all committers have the same rights.
● There is no leader, no boss, no «Benevolent
Dictator for Life».
● All the decisions have to be democratically made.
● It's the Apache Software Foundation model.

24. 11/17/15 OW2 con' 2015
How to become a committer
● When a developer has proved himself (by
doing pull requests, etc...), one of the
committers can propose to give him the
status.
● Then, other committers vote to decide
whether or not the candidacy is
accepted.
● Newcomers are welcome!

25. 11/17/15 OW2 con' 2015
Roadmap
● Each year, a «roadmap» is discussed by
the committers
● Define the objectives for the comming
year

26. 11/17/15 OW2 con' 2015
Sponsoring Company

27. 11/17/15 OW2 con' 2015
XWiki SAS (my employer)
● XWiki SAS is the company founded by
XWiki's creator, Ludovic Dubost.
● Provides support, hosting, and services
for clients interested in XWiki.
● Fund some committers (full-time jobs):
● Currently 6 committers are salaried of XWiki
SAS
● Most of the work done on the product comes
from these 6 persons

28. 11/17/15 OW2 con' 2015
XWiki SAS
● XWiki SAS also provides:
● The infrastructure (servers, etc...)
● A «quality team», who is in charge of
testing the new versions of XWiki and
contributing to the documentation

29. 11/17/15 OW2 con' 2015
XWiki SAS: angel or devil?
● XWiki SAS plays the game of Open
Source
● There is some committers who have no
relation with this company
● And that is good!
● Some committers are former employees
who keep their committer status (the 2
entities are distrinct so it's logical)

30. 11/17/15 OW2 con' 2015
XWiki SAS: angel or devil?
● Once a year, XWiki SAS employees
proposes a roadmap but then it's
discussed/modified by the committers.
● Nothing is imposed!
● XWiki SAS would love to see more
companies funding the XWiki.org project:
a win/win situation.

31. 11/17/15 OW2 con' 2015
XWiki SAS: angel or devil?
“Since XWiki SAS fund most of the
developers, the company must have a
great influence on the project...”
● Indeed... But other committers have still
veto, and developers from other companies
can join the project so that it would be more
«balanced».
● The current situation of being the main
sponsor is not an objective of the company.

32. 11/17/15 OW2 con' 2015
XWiki SAS: Open Core?
● The company does not apply an «Open
Core» strategy. All contributions are free.
● Consequence: the distinct between the
project and the company is well
managed.
● Maybe it could be more explicit by renaming
the project. The question has been asked
already.

33. 11/17/15 OW2 con' 2015
XWiki SAS: What is XCS?
● XWiki Collaborative Suite (XCS) is a new
project of XWiki SAS (the company).
● It's a distribution of XWiki (the product)
packaged with a collection of extensions.
● Including an extension to interact with
their (paying) support team.

XWiki SAS: What is XCS?

35. 11/17/15 OW2 con' 2015
XWiki SAS: What is XCS?
● XCS is still not an «Open Core» strategy.
● Actually, XCS is open source too (the
source code is available on github)
● But this project is not lead by the
community
● It has been developed to answer the
XWiki SAS needs for more customized
environnement (integration with the
XWiki SAS infrastructure, etc...)
●

36. 11/17/15 OW2 con' 2015
XWiki SAS: What is XCS?
● XCS is definitively not a danger for the
XWiki.org project.
● It's actually a good way to test our
extensibility: we try to make the project
modular enough so that a lot of different
distributions could exists, depending on
the users' needs.

37. 11/17/15 OW2 con' 2015
Health

38. 11/17/15 OW2 con' 2015
Health
● XWiki.org is healthy:
● Mailing lists are active
● Frequent releases
● A lot of downloads
● The XWiki democracy works and we are a
serious product in the competition
