Which reminds me - 7% of the US population has two middle initials in their
So why does most every computer system stateside insist on allowing only one
I get around this by putting in my first name as 'David RR' since there is no
checking on spaces in First names!
I emphasize on street addresses. I've never quite figured out why the USA
decided on 4 digit house numbers. In Europe you start from 1 and proceed. Very
few streets have more than 9,999 houses on them!!
The UPU has actual developed very good rules for all this stuff - but as I noted
earlier - there is no incentive - or means - for the schema-herd to avail
themselves of all this good work.
Notice how automation itself tries to impose artificial constraints to make the
life easier for the developers (another of my pet peeves). So instead of
permitting and managing edge conditions - they simply attempt to bulldoze them
away - aka only allowing a single middle initial is "good enough for most
In Venezula mail is still sorted by hand - this means that addresses have very
flowery and creative formats - depending on which part of town mail is for.
E.g. business district, posh part, or scruffy. In England you used to be able
to get mail delivered by putting just the Postal Code (which gets you to the
street, and side of the street) and then putting things like, 'third house on
the left, with pink shutters, past the 'Rose and Crown'. This of course is
very useful if you want to send a 'Thank You' note to the kind people who let
you sleep in their coal shed after a heavy session in the aforementioned
hostelry! But we digress...
Having constraint systems that can manage local contextual needs is clearly the
