Some time ago I watched a talk - I can not find it now. It was about a library which parsed Clojure code and stored it into Datomic/Datascript. Does someone have the link?
I believe you are thinking about the codeq library https://github.com/Datomic/codeq
I also seem to remember a video but I cannot find it.
There is this podcast where Rich Hickey talks about the library. http://thinkrelevance.com/blog/2012/10/12/rich-hickey-podcast-episode-019
There was also a library announced on the mailing list recently which does that (I think): https://github.com/jpmonettas/clindex
Read the announcement here: https://groups.google.com/forum/m/?pli=1#!topic/clojure/cV6rvgR9Pfs
That is no talk, but I figured you might be interested anyway.

This refers to a Clojure/conj talk – but I can’t figure out which one it was…
