Welcome! Please see the About page for a little more info on how this works.
In https://docs.datomic.com/cloud/time/filters.html - the "example inventory database" link to https://github.com/cognitect-labs/day-of-datomic-cloud/blob/master/tutorial/filters.clj is broken/404
These examples were moved into the Datomic Samples (https://docs.datomic.com/cloud/dev-local.html#samples) available in Dev-local. The link in the docs should likely now point to https://github.com/cognitect-labs/day-of-datomic-cloud/blob/master/tutorial/filters.repl
I will address the docs and update! Thanks for pointing this out.
