Hello.
Please try not to delete nycdoitt:bin= tag.
It records unique building ID which can be referenced in NYC's building database to get metadata about a given building.
If a building is demolished that tag is usually renamed to old_nycdoitt:bin= but still preserved because using the old id we can look up the new one.
