Presentation of co-authored MSR 2013 paper "A historical dataset for Gnome contributors", presented by Maelick Claes at MSR 2013, San Francisco. Abstract: We present a dataset of the open source software ecosystem GNOME from a social point of view. We have collected historical data about the contributors to all GNOME projects stored on git.gnome.org, taking into account the problem of identity matching, and as- sociating different activity types to the contributors. This type of information is very useful to complement the traditional, source-code related information one can ob- tain by mining and analyzing the actual source code. The dataset can be obtained at https://bitbucket.org/ mgoeminne/sgl-flossmetric-dbmerge.

Identity merging, Activity types
Identity merging
CSVAnalY2 hack
Semi-automatic identity merging based on name and e-mail.
5,923 after merging.
Activity types
Regular expressions on file extension, file name and path.
Coding activity e.g. .c, .h, .cpp, .py, .java.
Future work: CVSAnalY2 extension with refined activity types.
