[Talk-us-massachusetts] MassGIS address import -- on duplicates and weird housenumbers

[John Goodman]

Indeed. Two additional special situations that import scripts should be 
aware of:

1) Adjacent parcels that are both numbered the same in Mass GIS, but 
really one has an "A" or "REAR" suffix. For example, 28 and 28A.

2) "Half" addresses. Not too uncommon in the older neighborhoods around 
Boston. I've been entering these as, e.g., "10-1/2" -- not sure if 
there's a better syntax.
