Root directory content of the Khronos Registry (at khronos.org/registry/). Includes redirects for the old, pre-Github setup of the registry in .htaccess. Each API registry is maintained in a separate Github repository.
On the Khronos webserver, clones of these independent registries are located as immediate subdirectories of the root repository clone. They are renamed for brevity, e.g. Github repository KhronosGroup/OpenGL-Registry is kept in a local clone directory named just 'OpenGL'. This general pattern is followed with a couple of exceptions (Vulkan-Web-Registry -> vulkan, for example).
This repository rarely require updates. Its contents are little more than the toplevel registry index page, the Khronos Implementer's Guide, and the redirects. If it does need updates, they can be proposed at pull requests to the www.github.com/KhronosGroup/Registry-Root repository.
