Subject Re: Joining data by attributes

This might be a good case for LookupRecord [1] with a LookupService.

There appears to already be a SimpleCsvFileLookupService [2]. I think
that implementation is taking two columns out of the CSV and making a
map from them and then using that for the lookup. Not sure if that
works for what you are trying to do, but you could potentially
implement a custom LookupService if necessary.
