I will describe a universal encoding of string links in terms of Hopf algebraic structures. For this, I will introduce the notion of Hopf diagrams. Computing a quantum invariant of a 3-manifold reduces then to the purely formal computation of the associated Hopf diagram, followed by the evaluation of this diagram in a given category.
