Following this  discussion, it appears that the conditions into which
some documents are released by the Indian government are nearly the same as
CC-BY. However some people on Commons think that we need a confirmation.
Could the WM India ask whether the conditions specified here  are
compatible with such a license (or another free license)?
More precisely the requirement that images such be "Reproduced accurately"
is a moral rights clause -- a reproduction should not be modified to
misrepresent what the original work was. The rest of that clause also gives
a hint they are referring more to moral rights, as Carl Lindberg said.
