What is the dictionary between Witten's (Chern-Simons) invariants and Reshetikhin-Turaev (quantum group) invariants?

Question

Using Chern-Simons theory, Witten defined invariants of a framed link in a 3-manifold that are intrinsically 3-dimensional. From a mathematical perspective there is some ambiguity surrounding how well-defined these invariants are (they involve a path integral over the space of flat connections), but are thought to generalise the Jones polynomial. Around the same time Reshetikhin and Turaev defined invariants of tangles/links and 3-manifolds using quantum groups (I assume anyone who attempts to answer this question knows how these are defined). In one of their papers they state: "We believe that our invariants may be viewed as a mathemematical realisation of Witten's program". Does anyone know to what extent the dictionary taking me from one viewpoint to the other is now established?
