To enable maximum visibility among the developer community, these projects are often hosted in community project management portals. The current work studies one such portal, sourceforge. net by analysing the data of 200,000 projects and 2 million developers for the period Feb 2005 to Aug 2009. The scope of the present study includes the analysis of developer contribution. The slow growth rate of developer community and high number of single developer projects are the major findings of the present work.<\/jats:p>","DOI":"10.1145\/1943371.1943389","type":"journal-article","created":{"date-parts":[[2011,3,15]],"date-time":"2011-03-15T16:38:06Z","timestamp":1300207086000},"page":"1-5","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Analysis of Projects and Volunteer Participation in Large Scale Free and Open Source Software Ecosystem"],"prefix":"10.1145","volume":"36","author":[{"given":"Raj P.
