All aspects of the jfish project are licensed under open source licenses. The spirit of the project licensing is to prevent restriction and control of the project by any individual or commercial entity; to encourage the sharing, development, improvement and extension of jfish ‘works’; and by doing so to help empower health care workers in the developing world.

If your involvement runs counter to these ideals, then you are probably working outside of the project’s licensing.

In this context ‘work’ is used to mean any intellectual property derived from the jfish project, including, but not limited to:

  • Project documents and web-pages.
  • Specifications, design notes, manufacturing, maintenance and usage documents.
  • Circuit schematics, component lists and printed circuit board artwork.
  • Software and firmware source code.
  • Postings to project discussion forums, announcements and mailing lists.
  • Any other creative or intellectual product of the jfish project.

Under the project licensing you are free to:

  • Manufacture, use, copy, distribute and display the work.
  • Make derivative works.

Under the following conditions:

  • Attribution - You must attribute the work to the jfish project and the copyright holder.
  • Noncommercial - You may not use this work directly for commercial purposes (ie. sell it) but you can use it in a commercial context (ie. a private hospital).
  • Share Alike - If you alter, transform, extend or build upon this work, you must make the resulting work available for distribution under a license identical to this one. You must make clear to others the license terms of this work by including the full text of relevant project licences.
  • No warranty or liability is assumed or implied by the project contributors, authors or copyright holder(s).

Any of these conditions can be waived if you receive permission from the copyright holder(s). The FAQ covers further discussion on licensing issues and real world examples.
