I think the whole issue of verification and sources will need more attention
over time. We don't want to loose the verification back to OS Locator just
because there is a street sign, and what if the are two names with different
sources. source:alt_name? What about the situation where one name is
verified by the streetsign but another by the Street Gazetteer? Being
pedantic one could allow one to code a source as:
The ultimate delinquent case to me is the 1.2 mile section of the A14
running north to join the A1 to the west of Huntingdon. It is know and
referred to for different purposes as A14(M) and the A604(M). Online mapping
shows it as the A14 and the A1(M). Details in the Wikipedia article here in
the designation section.
Use of verified=no as a short-hand for 'I got this from an information
source but haven't yet checked it' allows one to then just click 'delete' on
the tag when it is verified.
