[Imports] NYC building + address import - to merge or not to merge?

[Pieren]

Another point which was not mentionned about this import is that I
found no "source" tag at all. The changeset comment is just refering
to a wiki link. I'm not sure if it would not be better to add a source
tag directly in the db, then being less dependent of the wiki (a page
can be moved x times and original link lost after some years). If the
Task Manager can insert automagically this in the changeset tags (plus
maybe the year of the original dataset release), it costs no
additional effort from the contributors.
