we will support attribute modification in the next version of 
netcdf-java (2.2), which may be ready by end of year (?)

as to whether that can be done without rewriting the file depends on the 
file; we are constrained by the version 1 file format. what would you 
need in that regard?

netcdf-4 (on top of HDF5) should be able to modify attributes without 
rewriting entire file.
