- XWiki downloads have increased steadily to over 30,000 per month since 2014. Active installs have also grown by around 9% per month. - While mailing list activity has decreased and commit activity has remained stable, issues filed and pull requests have increased in 2015, showing greater community involvement. - XWiki SAS contributes the majority of commits but external contributions have grown, although more could be done to attract contributors to projects under xwiki-contrib. - Overall, usage is growing significantly while development activity and the number of contributors has remained steady, suggesting actions may be needed to further engage the community.

2. Downloads
● In the past we had more distributions (XEClipse, Xoffice, Workspaces, etc)
● Good since 2014 (> 30K/month), what happened? :)
●
Note: figure for 2015 is extrapolated, we're at 240K on the 17th
of July
● APT/Deb distribution not included nor Extensions

3. Active Installs
● Progression of about 9% per month (2%+ per week) => +100%/year
● Would be interesting to have the history for total installs too to see how the retention
rate varies over time but more than download progresses (which are about 30%+ per
year on the past 2 years)
● However rate of AS seems to be slighty stagnating recently

4. Mailing List Activity
● Easier to use product? :)
● More knowledgable Devs, asking less questions, other support places on
the web?
● Should we move to Stackoverflow for users?

5. Commit Activity (excl. contrib)
● Moved to Git in 2011, less commits when using Git (no fear of merges)?
● Lost Sergiu
● Edy away for 1 year
● Some code moved to xwiki-contrib
● Seems stable for the past 3-4 years
● Need to do some stats that include contrib

6. Commits – Jul 2014 – Jul 2015
● Total: 46
contributors
● 32 from
XWiki SAS
(70%)
● 14 from
outside
(30%)
● But 80% of
top 24 are from
XWiki SAS

7. Commits (xwiki-contrib)
● No significant evolution of external contributors on xwiki-contrib (maybe 2015?)
● Yet it's the place where we expect contributors (code contributor)
→ We should highlight that extensions contributions is easier for newcomers

8. Source Contributors - Core
● Pretty stable since 2010 in # of core committers (but this doesn't take into account the
activity on contrib! We need to find a way to analyze this).

9. Releases
● Stable, team delivers regularly, on time!
● + 2 XCS releases
● + hundreds of Extension releases
● 39 releases in 2015 (excluding Extensions) => 1 release every 9
days
● Increase from 2014 probably means more bugfix releases

10. Issues
● Stable since 2010, surge in 2015!
● Significantly more improvements and new features in 2015
● More bugs fixed (quality increased) since BFD was put in place 3 years ago

11. Bugs Killing (Quality)
But lagging behind by 76 bugs for
the past 365 days!
Bugs created == Bug closed
over 1600 days (4.3 years)

12. Security Issues
● Roughly, we're closing security issues as they are created but we
have a backlog and we're not catching up with it
● Currently opened security issues: 40 (same as last year)

13. Contributed Extensions
● Relatively stable over
years. 70 new
extensions released
since last Seminar.

14. l10n
● Relatively stable in #
of contributors (about
30)
● Seems to be declining
but maybe simply
because we are closer
to 100% translations.
Would need to have
stats on completeness
for each language
instead!

15. Pull Requests (xwiki)
Nice increase of the external contributions but...

16. Pull Requests (xwiki)
● 7 Pull Requests waiting input from XWiki
● 5 Pull Requests waiting input from the author
● One probably died of exhaustion (26 comments)
→ Big Pull Requests are hard to apply
● One is probably expecting comment on Github
when it's on Jira
→ 2 places to comment can be a problem
● Some don't know which @since they should put
(and moreover, it changes all the time!)
→ @since should be filled by the merger

17. Conclusions & Actions
● No committer/contributor growth
● But usage growth: +9% / month, 100% per year for the past years
● Retention rate seems to be growing too
● Possible Actions/Ideas:
● Join a large foundation such as Apache/Eclipse
● Do a lot of tech marketing (write a book, talk at lots of conferences, write
lots of articles about XWiki)
● Create a Foundation and separate name of the project from company
name
● Join forces with another wiki project. Which one? Check how JSPWiki is
doing?
● Make it simpler to publish Applications to e.x.o (one-click publish)
● Make it simpler to develop Applications: WebIDE
● Organize an XWiki Day/Online Hangout and do that regularly to build up
a tempo
● Organize a Hackathon and do that regularly to build up a tempo

18. Questions?
