I haven't used Datomic but I thought its entire premise is that the data is immutable and thus history/versioning was baked in. Am I missing something?

That is indeed the premise of Datomic, so I'm not sure how that would be a differentiator in this case. Beyond that, it's hard to make any statements on the difference between the query languages without more examples.

Baked-in as part of the language; the query language is where it stands out. I'll get you examples of that.

FWIW, You can get transaction-time and the associated wall clock time in datomic's query language as well, though admittedly I can imagine cleaner ways of doing it :)

Cool; I didn't know that. Thanks, Chris.

I'm sorry we missed you at coffee on Saturday. The next one is in two months -- hope to see you then if you have time.
