(group-by :a1 data) produces the result that Shoeb was looking for.

I didn't see this original email for some reason, but here's a
simplified version:
(reduce
(fn [coll {a1 :a1 :as value}] (update-in coll [a1] conj value))
{}
data)
This takes advantage of update-in passing nil if it doesn't have the
key and conj with nil returning a seq of one value.

Wrote the following function which did the trick:
(defn partn [data]
(let
[add-mapping
(fn [m v]
(assoc m v (filter #(= v (:a1 %)) data)))]
(reduce add-mapping {} (set (map #(:a1 %) data
