Comment: Migrated to Confluence 5.3




FeatureEvents have long been something missed in the GeoTools library; the uDig project has hacked a few DataStores into submission way back in GeoTools 2.2. Now that we have updated to GeoTools trunk it is time to talk about what we have learned and see what can be cleaned up. Conversely FeatureEvents have not been implemented by the various DataStore implementations; in part that is probably due to a lack of clarity and available test cases; we need to take implementation experience into account and provide an event notification system that can be implemented.
