  A map is an abstract visual representation of a region, taken from a given
space, usually designed for final human consumption. Traditional cartography
focuses on the mapping of Euclidean spaces by using some distance metric. In
this paper we aim at mapping the Web space by leveraging its relational nature.
We introduce a general mathematical framework for maps and an algebra and
discuss the feasibility of maps suitable for interpretation not only by humans
but also by machines.
