Subscriptions are a new feature in UDDI version 3. With a subscription a registry will periodically send a Find or Get type message to an inquiry port and return the results to an email address, service or container attached to your account.
BEA AquaLogic Service Registry 3.0 allows you to publish subscriptions under your user account. Each subscription should be set with a limited time to live based on the number of notification messages to be sent, or an expiration date, or an OR'd combination of the two. However indefinite subscriptions can also be established.
Keep in mind that as when accessing records normally, authorization restrictions still apply when being queried or retrieved by subscription.
