51 * From [[OW2 Download stats>>http://stats.ow2.org/downloadStats/]] (requires credentials)
52 * These download figures contain [[all the distributions provided by XWiki on OW2>>http://forge.ow2.org/project/showfiles.php?group_id=170]].
53
54 Interpretation:
55
56 * At one point we had more distributions (workspaces, xeclipse, xoffice, xwatch, etc) and this could have lead to more downloads
57 * Since XWiki 3.3 we now have a [[Debian distribution>>platform:AdminGuide.InstallationViaAPT]] (.DEB), installable through [[APT>>http://en.wikipedia.org/wiki/Advanced_Packaging_Tool]] and we don't count those downloads in the figures above. They could account for an important part, we would need to retrieve their stats.
58 * Since XWiki 8.4 we now have [[Docker images>>https://hub.docker.com/_/xwiki/]] too.
59 * These download figures need to be correlated with the [[Active Installs>>xwiki:ActiveInstalls.WebHome]].
60 * These downloads do not count XWiki Extensions.
61 * The majority of XARs are downloaded from the Extension Manager and are not counted in these stats.
62 * In 2018 we stopped publishing our binaries on OW2 and thus we don't have the download figures since then. In addition, since we have several distribution channels (APT, Docker, xwiki.org, etc), it's impossible to track the download numbers. Thus we're now relying solely on Active Installs figures which provides a better tracking metric.
63
64 **Corrected Graph**:
65
66 We're using the [[Active Install Distribution proportions>>xwiki:ActiveInstalls.DistributionData]] to correct the download figure above.
67
68 Note that the Distribution data are only retrieved for XWiki 8.4.4+ so the corrections make sense only from 2017+ and they only been applied from 2017 forward.

169
170 Interpretation:
171
172 * See also the [[Commit Activity on Ohloh>>https://www.ohloh.net/p/xwiki/commits/summary]] which also shows a small commit slowdown since 2011 (i.e. since we moved to Git)
173 * Starting in 2011 we moved to Git (we were using SVN before) and this could have caused some difference in # of commits. For example sandbox and contrib code was moved in different Git repositories. In addition it's possible that using Git generates less commits because with SVN merges were a pain and thus devs were committing very frequently to not have to perform merges... ;)
174 * Some projects have been deprecated and moved to contrib such as XEclipse, XWatch, XOffice, Workspaces, XEM, etc and this has probably resulted in reduced commits
175 * We had 7605 commits in 2011 means about 20 commits/day. This is to be compared to [[other well known projects in 2011>>http://openlife.cc/blogs/2010/november/how-grow-your-open-source-project-10x-and-revenues-5x]]:(((

203 Analysis:
204
205 * For the full list of committers and their stats see also the [[Hall of Fame>>HallOfFame]].
206 * Seems the number of contributors has been steadily increasing till mid 2011 and from then on it's pretty stable between 8 to 15 different contributors each month.
207 * Thomas Mortagne is increasing his lead and is moving towards a 30% commit share for all times (27% ATM and 30% for 2015)
208 * Sergiu has reduced his participation, that's too bad! Come back Sergiu :)
209 * Jean-Vincent has left the project and is no longer active unfortunately
210 * Vincent is reducing slightly from 20% all time to 17% for 2015
211 * Marius is stable at 9%
212 * Guillaume is increasing: from 2% all time to 15% for 2015
213 * Eduard is also increasing: from 2% all time to 10% for 2015
214 * Pretty stable in # of core committers (but this doesn't take into account the activity on contrib! We need to find a way to analyze this).

238
239 Analysis:
240
241 * Activity has been stable for the past few years. This needs to be correlated with [[the size of the team>>||anchor="HSourceContributors"]] which has also remained stable during the same period.
242 * In the 5.x cycle (From December 2012 to December 2013) we've increased a lot the number of bugs fixed thanks to our [[BFD strategy>>Community.XWikiDays]] (one per week during this period). In the 6.x cycle (Jan 2014 to Dec 2014) we've reduced this by doing other types of XWiki Days but still doing BFDs to keep bugs at bay.

315 * At some points we were releasing other projects in addition to XWiki Enterprise (XWiki Office, XWiki Enterprise Manager, XWiki Watch and XWiki Eclipse).
316 * Pretty stable release cycle which means we're globally following strictly our release plans at a rate of about 30 releases per year, that's 1 release every 12 days, or 2.5 releases per month. Our [[release strategy>>VersioningAndReleasePractices]] is to release a minor version every 2 to 2.5 months in average. However we do release milestones, RCs and bugfix releases too.

344
345 * You need to correlate created vs closed security issues as otherwise it doesn't mean much.
346 * For the past 4 years, we're closing slightly less security issues than there are issues created (77 closed vs 83 created).
347 * Note that there are various criticity levels in security issues and some are of minor importance while others can be important.
