I've spent a day looking at Irmin, trying to figure out the JSON CRUD interface, but there's just no documentation, and the irc channel is pretty much dead. The code looks good, but it's my first introduction to OCaml, coming from Clojure. Would love to see some more documentation on it.
Irmin's still being developed, hence not many docs at the moment. Apologies there was no-one responding in irc (I assume you mean #mirage - there are usually 30+ folks there). The mailing list is quite active and is a good place to pose questions.
