Bitemporal Data

Datomic's transaction time models the time at which data was recorded. In many domains, it is useful to model other timelines, such as the time for which data is known to be valid.

In Datomic, you can model these additional timelines by creating your own :db.type/instant attributes, and then creating and searching for them with normal transaction and query approaches. It will often be efficient to make such attributes properties of the transaction itself.
