I will construct differential graded Lie algebra models for classifying spaces of automorphisms of
bundles and I will discuss how to find Chevalley-Eilenberg cocycles that represent generalized
Miller-Morita-Mumford classes in these models. This leads to a new approach to tautological rings
for simply connected manifolds.
