OpenGL documentation source

Question

I know that Khornos group owns opengl. However, both opengl.org and khronos.org domains host the documentation.

What is the official source of documentation for opengl?

Answer 1

Khronos also owns the opengl.org domain. http://whois.domaintools.com/opengl.org

So both can be considered the official source of documentation though it's easier to find on the registry on https://www.opengl.org/registry/
