Topology is the natural setting for studying continuity (even though
its definition
looks rather counter-intuitive, but it makes much more sense if one
sees its emergence from metric spaces). "Preserving properties" is something
assigned to functions and transforms and not topological spaces themselves,
or any algebraic structure or mathematical constructions of this kind.

What we're talking about here, if we decide to be mathematically rigorous,
is rather a Directed Graph Isomorphism.
