Abstract: Many open source projects have long become commercial. This paper shows just how much of open source software development is paid work and how much has remained volunteer work.

This paper provides a model of individual product features, rather than full-fledged business models, and their perceived value to customers. The model is the result of a three-iteration study, including interview analysis, literature review and the implementation of an…
