But after that future updates can work via conflation. Deletions are the
most important type of update: it remains to be seen how good the USPS data
will prove out here. What's the lag between discontinued collection, and
the database reflecting that? Does the data ever miss a box that's
actually active?
you need to flesh out the update process, "conflation" is easier to say
than it
is to do.
how will you tag so as to allow correlation between previously imported USPS
data and updated USPS data? how do you propose to resolve conflicts where
a mapper has modified previously imported USPS data and the new USPS data
is different from the prior data? how do you propose to determine if a
deletion
is proper or an error on the part of the USPS?
