OSVR HDK Module Development Kit License FAQ
What Open-Source licenses are being use?
OSVR has two separate parts that are both made available open-source:
  • Software - The Software Development Kit License will be, like Android, under Apache 2.0.
  • Hardware – For hardware there is no clear standard for open-source licenses, so we modelled the Module Development Kit (MDK) after Google’s Project Ara Module Development Kit.
What do I need to know about the MDK?
It is fully open-source (i.e. you can download it freely and make derivative works to it). However, any derivative work and modifications to the Hacker Development Kit and schematics are automatically licensed back to Razer who can then re-license it back to the community under the MDK.
Will my own existing Intellectual Property be licensed back to Razer?
Absolutely not. The only IP that is licensed back to Razer is any directly modified work of the Hacker Development Kit which is licensed under the MDK (i.e. derivative works). For example, if a gesture camera company downloads the CAD of the HDK and modifies the frontplate to allow for a mount for their gesture camera, the mount itself (as a derivative work of the HDK) will be licensed back to Razer (for onward licensing to the community), but the rest remains the IP of the gesture camera company.

Integrated Gesture Camera Faceplate
Licensed back under the MDK:
Not licensed back:
Faceplate Mount (as derivative work to the HDK)
Gesture Camera
Why the need to license back my work to Razer in the first place then?
This is to prevent 3rd parties from taking advantage or control of the hardware ecosystem.

That clause is in place so that Razer can ensure all derivative work to the HDK can be licensed back to the community via the same open-source license. This prevents any developer that creates hardware based on the MDK to create a closed off system based on work derived from the HDK. As such, this guarantees that the OSVR Hardware stays completely open while allowing any company to still protect their own IP.
I still have concerns. How can I let you know?
Please do provide your feedback to us directly in the MDK Discussion thread on the OSVR Forum here. We’re open to feedback and will take all feedback into consideration for potential improvements/clarifications on the MDK license.
