|Type||Virtual reality and augmented reality API|
OpenXR is an open, royalty-free standard for access to virtual reality and augmented reality platforms and devices. It is developed by a working group managed by the Khronos Group consortium. OpenXR was announced by the Khronos Group on February 27 2017 during the GDC 2017. A provisional version of the standard was released on March 18, 2019 to enable developers and implementers to provide feedback on it.
The standard aims to eventually provide two components: an API aimed for application developers, and a device layer aimed for the virtual reality or augmented reality hardware, presenting an abstraction interface with the device itself. The 0.90 provisional release contained an API, with the device layer being planned as a plugin interface for post-1.0 releases.
In March 2017, the Khronos Group tentatively planned to release the first version of the API in late 2018. The API was released in March 2019 as a provisional release, with a plugin device interface being planned for post-1.0 releases.

The OpenXR standard comes in two parts. First, the Application Interface, which application developers and middleware providers write to, and which serves to define and combine common, cross-platform functionality(...)Next, the Device Layer allows VR/AR runtimes to interface with various devices

With regard to their OpenXR effort for an industry standard VR, we won't see the fruit of this work until next year. Currently, the tentative target appears to be for holiday 2018 but we may see some companies showing off efforts earlier in the calendar year
