Tannaka duality originally looked at reconstructing compact Lie groups or linear algebraic groups from their categories of representations, and characterised such categories. Joyal and Street generalised this to recover a coalgebra from its finite-dimensional comodules. I will show how to extend this to dg coalgebras and dg categories, via derived Morita theory.
