This data enables and supports research in areas such as software engineering, open source phenomena, social network analysis, data mining, and project management. This newly-formed database containing Concurrent Versions System (CVS) and Subversion (SVN) metadata offers new research opportunities for large-scale OSS development analysis. The CVS and SVN data is juxtaposed with the SourceForge.net Research Data Archive [5] for the purpose of performing more powerful and interesting queries. We also present an initial statistical analysis of some of the most active projects. }, keywords = {berlios, cvs, savannah, scm, sourceforge, srda, subversion, svn}, isbn = {978-3-642-13244-5}, issn = {1861-2288}, doi = {10.1007/978-3-642-13244-5_40}, author = {van Antwerp, M. and Madey, G.}, editor = {{\r A}gerfalk, P{\"a}r and Boldyreff, Cornelia and Gonz{\'a}lez-Barahona, Jes{\'u}s M. and Madey, Gregory R. and Noll, John} } @article {Beecher2009739, title = {Identifying exogenous drivers and evolutionary stages in FLOSS projects}, journal = {Journal of Systems and Software}, volume = {82}, number = {5}, year = {2009}, pages = {739 - 750}, abstract = {The success of a Free/Libre/Open Source Software (FLOSS) project has been evaluated in the past through the number of commits made to its configuration management system, number of developers and number of users. Most studies, based on a popular FLOSS repository (SourceForge), have concluded that the vast majority of projects are failures. This study{\textquoteright}s empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities are formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project{\textquoteright}s potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success.}, keywords = {developers, forge, forges, repositories, repository, scm, software repositories, sourceforge, success, users}, issn = {0164-1212}, doi = {DOI: 10.1016/j.jss.2008.10.026}, url = {http://www.sciencedirect.com/science/article/B6V0N-4TVTJFS-1/2/e32ecee1bcb54bd4a5dff6d5e3daca8d}, author = {Karl Beecher and Capiluppi, Andrea and Boldyreff, Cornelia} }
