This grant supports research by information scientists Matt Germonprez (University of Nebraska) and Sean Goggins (University of Missouri) to develop and test rubrics for the evaluation of the health of online, open source development communities. Building on previous work that resulted in the successful Community Health Analytics for Open Source Software (CHAOSS) project and using a rich dataset drawn from GitHub and other sources, Germonprez and Goggins will investigate how definitions of the health of an online community might rightly vary depending on the type of community in question or type of project being jointly developed, how the injection of money into an online development community influences individual contributor behavior, and how individual decisions by contributors impact overall community health.
