    Like many in the professional open source business, we have been experimenting with our license. There is no model company that any startup can point to say that’s the way to do it. Companies like SugarCRM, Zimbra, Pentaho, Jasper and Alfresco have altered our licenses as we navigate through the development of our respective businesses. We were particularly concerned when we were starting up that people would take advantage of our innovations before we had a chance to build our brand.

    We have now built one of the stronger brands in open source and so our original concerns around the protection that we had from attribution no longer apply. We have also been tracking the conversations on attribution that have occurred in the OSI through our colleague Matt Asay who is on the board of the OSI.

    Look forward to an announcement from Alfresco in this area soon.
