The set of nilpotent rational homotopy spaces with given cohomology algebra H forms a "moduli space". In fact, it has the form M = Aut H\ W /U, where W is the cone over a projective algebraic variety, and U is a unipotent algebraic groupoid. We outline the construction, which proceeds from the observation that W is the base of the "miniversal deformation" of the formal space F with cohomology H. We also relate the construction to the classifying space BAut(F) and give examples and problems.
