--- this is another kettle of fish then. I guess there is two houses
of thought on this.

1) If they user didn't explicitly state the structure then you
shouldn't mess with it. Is it better to have some false positives and
more data, or less data, but have it be more correct? In this case,
the bot shouldn't add anything.

2) The other idea is that if it looks like a duck, quacks like a duck,
then it's a duck. Would attempt to make anything that looks like an
ADR into an ADR.

You are attempting #2 and trying to minimize any false-positives.

OK, i think we're on the same page now. There is a LABEL property in
vCard for a "label" representing an address. This is unstructured, and
therefore probably not much use when it gets fed to external
applications like Operator to a Map.

The vCard RFC says:

The structured type value corresponds,
   in sequence, to the post office box; the extended address; the street
   address; the locality (e.g., city); the region (e.g., state or
   province); the postal code; the country name.

It gives an example of what "locality" could mean (e.g. city) but
doesn't discount what it can't be. The same for 'street-address' it is
not explicit about that it MUST have a number or if just the
street-name would suffice. The only other sort of "catch-all" is

I personally would probably use 'extended-address', but that would be
just personal preference. (partly because an importing app like
Outlook might not accept multiple locality "cities" and drop one,
whereas the chance of extended-address colliding with others is very
low) The important part would be to get the data into the customer's
address book, then they can easily copy-paste-CrUD as needed.

i hope this helps,
