What types of description are not representations? Is a musical score 
a representation of music? Is Labanotation a representation of a 
dance? Is a list of driving instructions (turn left, go 15.2 miles, 
turn right,... ) a representation of a route? Is a list of boundary 
points a representation of a building plot? Is a list of convex 
solids encoded using cyclic homology with numerical coordinates for 
vertex points a representation of a 3-d object in a CAD system?

I would say 'none' for the first question and 'yes' for all the others.

Yes, if "represent" means "copy". But it doesn't, in most of the 
English-speaking world.
