Intellectual Property Considerations
All materials contributed to nanoHUB.org must have clearly defined rights and privileges. The NCN has instituted the following guidelines for all materials uploaded onto nanoHUB.org:
Simulation tools can be made available online through nanoHUB.org's unique middleware, so users don't have to download or install any source code. As such, the source code for your tool can be completely protected, and may not require any license. We do encourage our developers, however, to release their tools as open source so that others can build upon their work. Purdue University has a process in place at the Office of Technology and Commercialization (OTC) to approve code written by Purdue employees for open source release. The Purdue OTC office prefers the NCSA-style license. Other NCN universities may have their own policies for licensing and code release. Please check with your local institution for details. If you decide to make your source code available for download, we do require that you include some well-defined license so that our users clearly understand how they are allowed to use your source code.
Online Presentations and Other Materials
We strongly encourage contributors of online presentations, teaching materials, animations, and other materials to adopt the Creative Commons 2.5 license. This allows others to use your work for non-commercial purposes, but they must acknowledge you as a source and share their derivative works under the same license. Note that this also gives you an opportunity to build upon their work!
