What is meant by smooth orbifold?
Edit: Nov. 26, 2015
Another example about how diffeology represents the smooth structure of orbifolds: the Seifert Orbifolds, as space of fibers of a "Seifert fibered manifold":
http://math.huji.ac.il … So if you are interested in diffeomorphisms of the orbifolds, go directly to the group, and analyze it. …

Orbifold fundamental group in terms of loops?
I don't really looked how the homotopy for diffeological orbifolds, or the homotopy of the orbits of the group of diffeomorphisms, and the structure groups of the orbifolds (here ${\bf Z}_m$ at the origin … ) are related, but it has its own logic and it is a diffeological invariant (I consider only what is called "effective orbifolds"). …
