Are FLOSS developers committing to CVS/SVN as much as they are talking in mailing lists? Challenges for Integrating data from Multiple Repositories

This paper puts forward a framework for investigating Free and Open Source Software (F/OSS) developers activities in both source code and mailing lists repositories. We used data dumps of fourteen pro jects from the FLOSSMetrics (FM) retrieval system. Our intentions are (i) to present a possible methodology, its advantages and disadvantages which can benefit future researchers using some aspects of the FM retrieval system’s data dumps, and (ii) discuss our initial research results on the contributions developers make to both coding and lists activities.
