  1. Discussion • Can we create an Open Source Radiation Belt Community? • Discussion outcomes • List of Space Radiation Climatology codes that may be useful. There is a list of codes at http://virbo.org/#Resources • How can Virtual Observatories help? Implementing algorithms as a service? • List of algorithms that we would like to have in an Open Source form.

  2. Important • The question of how and if old code bases should be “opened” is not part of this discussion.

  3. Important note • Geoscientific Model Development - An Interactive Open Access Journal of the European Geosciences Union • http://www.geoscientific-model-development.net/index.html LANL* V1.0: a radiation belt drift shell model suitable for real-time and reanalysis applications J. Koller, G. D. Reeves, and R. H. W. Friedel http://www.geosci-model-dev-discuss.net/2/159/2009/gmdd-2-159-2009.html

  4. Background for Discussion • “Open Source” versus “Open” • “Open Source” usually mean “OSI-compatible license” [http://www.opensource.org/] • “Open” usually means you can view source, but there are restrictions, often in the “be a good colleague” spirit

  5. Background for Discussion • Does it matter if code is open? • No: Simple code - Easier to write algorithm based on write-up in paper • Yes: Just right code – Long enough so that there is a benefit to investing time in compiling and reading docs • Maybe: Large, complex code - Treat output as result from experiment where very few people have/want access to the instrument?

  6. Background for Discussion • How much duplication is optimal? • Simple code – many • Just right – one or two • Large, complex – Four
