Query: Translation Groupoids and Orbifold Bredon Cohomology   We show that the bicategory of (representable) orbifolds and good maps is
equivalent to the bicategory of orbifold translation groupoids and generalized
equivariant maps. We use this result to define an orbifold version of Bredon
cohomology.
