OpenGL ES 2.0 is a standard , described in specification document (and headers files) that you can get from khronos (http://www.khronos.org/registry/gles/). It is not an opensource. Based on this specification there are some implementations of opengl es 2.0 being developed. Some of them are listed on: http://www.khronos.org/developers/resources/opengles/ .Â
