is the znear and zfar that I specify in

ortho (T const &left, T const &right, T const &bottom, T const &top, T const &zNear, T const &zFar)

Is it in camera space or in world coordinate system?

The coordinate system is whatever is used by the coordinates you're transforming with the matrix.

The transformation created by glm::ortho() will transform Z=-zNear to Z=-1 and Z=-zFar to Z=1.
