We're working on a project that uses the Datomic Pull API to pull specific attributes out of Datomic entities. Here's an example of query that uses the Pull API:
(d/q '[:find [(pull ?e [:sales/deal_number :sales/deal_close_date :sales/state]) ...]
:in $ ?date
:where [?e :sales/deal_close_date ?d _ _] [(> ?d ?date)]]
