The synchroniser updates EBRIM with ISO19139 data. So the data goes from ISO19139 to EBRIM, never the other way around. The Ebrim Updater does this every time ISO19139 is added or updated in the GN persistent storage.

Other behavior:

• EBRIM client only reads from GN
• ISO 19139 client can read and write (harvest)
• Ebrim Updater does a one time conversion of all the ISO 19139 data into EBRIM
• Ebrim Updater updates EBRIM Persistence whenever GN Persistence gets updated
• All information at course grained level can be found either via CSW/EBRIM or CSW/ISO19115
• All information at fine grained level can be found via CSW/ISO19115
• Not all information at fine grained level can be found via CSW/EBRIM. This because the EBRIM model does not cover all the details/semantics of the ISO19115 model
