NA-MIC Governance Software Sharing: http://grants1.nih.gov/grants/guide/rfa-files/RFA-RM-04-003.html • …software should be freely available … • …permit the commercialization of enhanced or customized versions … • …include the ability of researchers outside the center and its collaborating projects to modify the source code and to share modifications …
BSD Style License • Open Source • No license fees • No restriction on use • Clinical and commercial uses do not require our permission • No guarantees • User is responsible for making sure that the software works, we promise nothing. Same for compliance with all regulations. • E.g. if you want to use our software for clinical trials, you have to apply for the proper authorizations at your institution • NO requirement to give your code back to open source (NOT viral). • You can contribute code back to us, if you want to do that and it is our decision if we will accept it. • Acknowledge our contribution • See http://www.slicer.org for more information
FOSS – A Public Highway… • Open-source is like a Public Road System • Provides Infrastructure for a Variety of Uses • Driveways can Lead to Anything: • a Public Park • a Private Facility FOSS= Free Open Source Software Provided by Pieper, Kikinis
