The heavy concentration of Apache developers here at the ApacheCon US
in Atlanta got me thinking about how the various Apache projects are related and whether we could come up with some ways to visualize the existing (and emerging) community patterns.
As a quick first step I just took the committer lists of all Apache projects (excluding meta-projects like Jakarta
) and ran it through an ad-hoc Perl script that identified any pairs of projects that have five or more committers in common. Running those relationships through Graphviz
produced the following diagram:
Interesting stuff... Of course the committer lists are not a very accurate source of information as many committers are no longer active in the projects they once contributed to, so I perhaps should be looking at svn commit logs instead, but as a first approximation the above diagram is already quite nice.
