I agree with Jason's comments on the ID, though. Post-import, it's
pretty useless. I think the idea is that it would be useful several
years down the road when a new data dump is taking from an upstream
source to match changed buildings, but there's no guarantee that the
ID's from the external source would even be consistent (i.e. the
building on the corner of Dauphine and Contie with ID=1234 may not
have the same ID 2 years from now after the upstream system goes
through upgrades, software changes, etc.)
+1. as serge is fond of pointing out, many imports have gone to the
trouble of
preserving ids with the idea that they'll help with conflation of
updated data
sets years down the line. there are no known examples of this actually
happening.
