OpenXR is from Khronos and allows developers to create applications for virtual and augmented reality that can run on any platform that has OpenXR APIs.

Unity, Valve, Intel,AMD, Oculus, and several other large companiescurrently publicly support OpenXR according to Khronos' website. Earlier this year, Microsoft's Alex Kipman weighed in on the importance of OpenXR.
