Abstract

Most empirical studies about Open Source (OS)projectsor products are vertical and usually deal with the flagship,successful projects.There is a substantial lack of horizontal studies to shed light on the whole population of projects,including failures.This paper presents a horizontalstudy aimed at characterizing OS projects.We analyze a sample of around 400 projects from a popular OS project repository.Each project is characterized bya number of attributes.We analyze these attributes statically and over time.The main results show that few projects are capable ofattracting a meaningful community of developers.Themajority of projects is made by few (in many cases one)person with a very slow pace of evolution.
