I doubt very much that there is a timeline. It's a product and the last I heard was staying close sourced. Having said that, I would not be surprised if some of its libraries are open sourced. I know of at least one that is in the pipeline.

Datalog for clojure's data structures would take Clojure to a new productivity level. It would also greatly simplify a lot of the code out there today, further driving software to be more data-oriented. Data is the ultimate API. Please make it be Datalog.

The datomic-free jar provides Datalog. I use it myself https://clojars.org/com.datomic/datomic-free.

Datomic Free gives you that capability right now, for free, no strings attached, and no need to use a Datomic db. Not open source, but free as in gratis, a la Creative Commons.

We may trim down the deps a bit for that use case.

A trimmed down version is great news. Datalog makes Clojure so much better! Ideally it would be part of Clojure itself, but I'll take what I can get :)

I would also love to see a trimmed down version just to use datalog.

I'm working on a port of BloomL for clojure which will include a semi-naive datalog interpreter (it will already support naive, monotonic datalog by tonight). It will likely never be as well optimised as the Datomic libs but it is LGPL.

If you say the datalog query aspect of Datomic, I would be tremendously (maybe embarrassingly) happy.
