Both.  In the lower level, tags are added by the camera adapter, the 
circular buffer, and supplemented by everything the Core knows about the 
system (i.e., the complete system state cache is added). Metadata are 
then transferred to the Java layer, where some normalization happens, 
and a few things are added.

For fast acquisitions, it would be clearly beneficial for the lower 
layers to only send the full system state with the first image, and 
things that change from the previous image from then on out.  Not a 
trivial undertaking, as the upper layers also needs to ways to 
understand this alternate organization of metadata, and want to stay 
backward compatible.  Definitely something to look at, but there is 
quite a bit to deal with already:
