from our previous communications I assume that you are interested in=20
data for statistical analysis across a large number of projects, for=20
research purposes?

You already know that CVS log data can be used to quantify individual=20
developer contribution over time and code area (insert disclaimer here=20=

about validity of Lines of Code as a productivity measure).

CVS Tags and CVS Branches can provide some insight into the versions=20
and releases of a software product. Time between releases, number and=20
patterns of commits between releases etc.

Brian has already pointed out that CVS comments are often used to refer=20=

to bug numbers from bug tracking software. These CVS comments might be=20=

used to analyse # of bugs fixed per developer, time of bugfixes and=20
similar things.

On a related note: You have already mined SourceForge.net for CVS data.=20=

SourceForge also provides bug trackers for projects, similar to those=20
mentioned by Brian. You might use screen scraping technology to extract=20=

data about bugs from these trackers (date opened, date closed,=20
developers involved). CVS comments might be used to cross-correlate=20
this data with data from the CVS.

The problem with all those data sources is that they are not used in=20
the same way across projects. Analysis would involve *much* more manual=20=

labour. That's why I'm not sure if that will be practical.
