Technical approach and business requirement do not relate one two one, giving rise to potential hybrid approaches.

Event The reference Architecture for the DE4A projects focusses the Subscription and Notification Pattern on Event Notification, which can be combines with the Lookup Pattern to cover the updating previously shared evidence use case.
