Title: Derivators as models of a sketch

Abstract:
We construct a sketch enriched in categories, having the 2-category of
derivators as its category of models. Derivators were introduced by
Grothendieck with the purpose of solving some of the flaws of
triangulated categories; however derivators provide also an
alternative axiomatic approach to homotopy theories. As an application we
expect to find an intrinsic characterization for derivators of small
presentation, whose 2-category is equivalent to the pseudo-localization, at
Quillen equivalences, of the 2-category of combinatorial model categories.
