Subscribers need to support querying for all data of interest to them when they first enter a zone. After that, if they are subscribed, they can stay up to date by listening to events.</p> <p>A well-written subscriber agent should have the capability to resynchronize at any time, so that if the administrator of the agent thinks that it is out of date, it can sync up. In addition, a good subscriber agent should expect to resynchronize every year at the start of school. There is no guarantee that SIF events alone will be able to keep the subscriber in sync during end of year processing in the SIS, so the subscriber should plan to resync after that is complete.</p> <p>A subscriber should not unregister when it shuts down. If it does, any events that it could have received during that period will be lost.</p>
