>The systems which have been accredited for supply of BS7666 data will reject punctuation as part of their business rules
Which, of course, is just because it is easier for the implementation, not because the standard calls for it. But then, as Christopher Roper, in an official memorandum to the Select Committee on Transport, Local Government and the Regions back in 20021 said:
Christopher Roper said:
All kinds of data (including the NLPG) claim BS7666 compliance, but it is gradually dawning that this standard can be applied in a variety of different ways, and says nothing about the consistency, currency or completeness of the dataset. All it guarantees is the structure of each record
What he didn't foresee was that a limited interpretation of the structure would then become the de facto
It's a bit like deciding we want a database that is to store real numbers. Except we all know that it is difficult to store real numbers accurately on a computer, so a decision is made to only store integers (every integer is a real number, so from a standards point of view that's ok). Only now we turn things around and use that limitation, perhaps by ensuring that no system that interfaces with the database can accept anything except integers (and possibly helped by legislation), to dictate that the only real real numbers are integers.
I'm looking forward to the day that, when someone asks where I live, I reply "Oh, 100023336956" which is of course the logical extension of where the NLPG is going ...
(I leave it as an exercise for the reader to figure out to which address the UPRN above actually refers)
>The NLPG is gradually being recognised as the authoritative UK gazetteer
Certainly Intelligent Addressing's propoganda would have you believe that ... but I'd counter that the Ordinance Survey's* Address-Point and the Royal Mail's PAF are rather popular. And both allow apostrophes; sadly the number is dwindling because, as local government arbitarily removes them from old addresses Address-Point and PAF are obliged to follow suit since, as Rosie has said, thanks to an Act of Parliament, local government is the authoratitive arbiter of address names.
*As far as I can tell from my reading Ordinance Survey and Intelligent Addressing loathe each other ...
