The creation of the Enterprise Open Source Directory (short: EOS Directory) in 2007 by Optaros has been triggered by a clear need of enterprises and organizations asking for help and advice to identify and select Open Source technologies. With roughly 250 Open Source platforms, solutions and frameworks listed and rated initially, EOS was able to establish itself as a source of reference in this space. Since then EOS Directory has continuously grown, listing more than 350 projects today and building up a vibrant community of visitors and input contributors. The EOS Directory Blog has become one of the key voices in the Open Source scene.In early 2009 Optaros has handed over the EOS Directory platform to Bruno von Rotz, a well known Open Source specialist and consultant and the initial sponsor of the initiative. To strengthen the neutral approach to ratings and selection of the technologies, the new EOS Directory Advisory and Expert Board has been established over the last weeks. Initial members of the EOS Directory Advisory and Expert Board include Aleksander Farstad, Ce?dric Walter, David Nu?scheler, Gianugo Rabellino, Roberto Galoppini, Hannes Gassert, Hans Waarle, Joel Gardet, Matt Asay, Matthias Geisler, Michael Hanisch, Olivier Pe?pin, Raju Bitter, Ralf Hauser, Seth Gottlieb, Stephen Walli and Tiberiu Fustos, representing user and provider communities as well as international expert audiences. The Advisory and Expert Board will be both instrumental in guiding the future development of the EOS Directory Platform as well as in making sure that the content is accurate, relevant and fairly represented.During the next months the EOS Directory Platform will also be rejuvenated and updated to even better support Enterprises and Organizations in need for Open Source technologies’ selection and evaluation help.
