My money would be on duplication, the RDBMS would want to completly 
store the Coverage would it not?
(Your arrow goes both ways in your diagram).

That said you may have more luck keeping the searchable metadata in your 
RDBMS, and running a file cache
on the side to store the actual rasters. If you hide it behind an API it 
would be identical in use to storing the
coverages in the RDBMS, and would be much less risk then taking on an 
RnD task.


Question for coverage types, I was working on the GeoTools RnD Page the 
other day, updating its status & timelines.
Are you still content with the targets (Early next Year = January right 
now), and descriptions there?
