They should be moved to OHM but then ANY information that is superseded 
should be automatically archived to SOMETHING since we are now in a 
situation where much accurately mapped material is simply dumped when 
there is a change to the current situation. The 'delete' process should 
be handled in a manor more sensitive to the hard work that has gone before!

I have always disagreed that 'historic changes have no place in the 
database', since the vast majority of the material making up the 
historic data such as boundaries IS the same as the current 'live' data. 
Simply not downloading data that has a prior end date does not make 
anything 'unmanageable', in fact it makes life a hell of a lot easier 
since one can simply tag a section of the boundary as 'end_date=xxx' and 
add a new section with the boundary change as 'start_date=xxx'. The ONLY 
question is what happens to the data once it has an end date ... which 
may be some time in the future ...
