Hrushovski established a correspondence between definable groupoids and
internal covers, using the notion of binding groupoids. It was later shown to
be an equivalence of categories by Haykazyan and Moosa. They also managed to
extend it to the case of 1-analysable covers with independent fibers. There
was a suggestion to treat the more general case of 1-analysable covers using
simplicial groupoids. In this talk, I will present the internal case, describe
how the suggestion can (hopefully) be realised, and give a few examples.
