I've started adding Prow_ref=* to the paths within my Local Authority. I've

I noticed another mapper has already added a few, but using the format by
Barry Cornelius at rowmaps.com. I think this shouldn't be used as it's
Barry's own concoction.
As the LA is the organisation someone would most likely converse with about
PROWs, it seemed sensible to use the format issued by them. It makes
verification of any updates *much* easier.
I'd agree with that. However, one should be careful about drawing
conclusions about what the LA's official referencing system actually
is. The legal record of Rights of Way is held in the Definitive Map
and Statement, whereas we may well be using an electronic
representation of the definitive map for our mapping. In translating
the data to their computer systems, the LA may have altered the
reference format from that used on the Definitive Map. As others have
already noted, there are also inconsistencies in how an LA itself will
refer to their own paths.
I'm unsure why or how often "altered reference format" happens, but
would be a LA internal matter & irrelevant to OSM. We should be using
the references provided to us under OGL even if "different LAs use
different reference styles and with different degrees of consistency" or
there's "obviously different de facto standard in use by an LA".
OSM can't use any other format used by LA's if not issued under OGL.
OSM has to use a reference that relates to other databases. Concocting
our own makes these paths impossible to be "uniformly interpreted and
processed". AFAICS "Parish FP 12" isn't a "common standard"?
I've had a conversation with someone at my LA about a FHRS
establishment. I was able to indicate precisely & immediately which
restaurant by using the FHRS:ID number which was include in OSM
directly, *without* alteration, from their database. I would not be able
to do that for the equivalent footpath using OSM's wiki recommendations.
Are any LAs, that you've looked at, not including parish codes within
their refs?
But I would agree that we need to allow different formats to be used for
different LAs.
Good to hear.
