Re: [Talk-GB] PRoW Ref codes (WAS:Hampshire Rights of Way Data released under OS OpenData licence)
Is it not sensible to use the reference format of the place you are in, rather than create some sudo standard? If a footpath is in County Durham, and I see OSM has it as ref=Footpath 5, then I know I can call Durham council and say Repair footpath 5 please.. If another footpath is in Newcastle, and I see OSM has it as ref=NE/06-b, then I can call that council and say Repair path NE slash 06 dash b, please.. If I call Durham council and ask them to fix Footpath DH slash 5. they will just be confused why I'm saying DH and slash. Should there be a national referencing system introduced, or at least planned and adopted by some areas, then we can think about using tags such as *ref:uk*, *{name_of_standard}_ref*, or perhaps just *ref* and *old_ref* for the number/format previously used in the area.

Counties won't check with each other about uniqueness of the value, so it's only guaranteed unique and unambiguous within the context of a certain county. Hence, the ref must be accompanied with an indication of which county generated the ref. So ref=organisation:num is one way, ref:organisation=num is another. Just think of what happens in the case of a new path: who or what generates its ref? It would be nothing short of best practice to include the organisation in the tagging. Just like the principle which says that amounts are never recorded in financial systems without a currency code and timestamps must always have a timezone - to avoid all possibility of ambiguity.

Re: [Talk-GB] PRoW Ref codes (WAS:Hampshire Rights of Way Data released under OS OpenData licence)
Fantastic news about Hamps PRoW data :-) Anyone else contacting their local council can use this as an example case. Q: Do we need to have a suggested way of tagging the reference numbers in ref=* ? So far I have seen the following in use: * Parish / path no. / link no.== For example: 417/26/1 (where the parish is a number code) * Area RoW_type Path_no.== For example: North Tawton Bridleway 18 Delimiters seen include ' ' , '/' and '-'. A: Can I throw out the suggestion that we use: * Parish-RoWType-PathNo-LinkNo. (where the bit in brackets is optional). I assume that use of '-' is allowed.

Re: [Talk-GB] PRoW Ref codes (WAS:Hampshire Rights of Way Data released under OS OpenData licence)
I guess the thing to do is just use the most common reference. I am aware of several schemes: Hampshire uses parish plus number e.g. Tichborne Footpath 5, West Sussex uses a county-wide, 3 or 4 digit number (e.g. 1263, 2005) and I've also seen XXX/YY (in Wrexham borough, Wales) and very large, 6-digit numbers (Cumbria). We should probably just make it free form rather than enforce a particular format.

I think this is going to be complicated by the fact that different councils use different schemes for their numbering. I believe that the traditional method would be for paths to be numbered with a sequential number within each parish. The Definitive Statement forms often make use of the abbreviations FP, BR, RB and BY for the four classes of right of way, so I've been using the following format: ref = Parish Name Type Number where Parish Name is the name of the parish (which may itself contain spaces), Type is one of the strings FP, BR, RB and BY, and number is the path number (usually an integer, and without any leading zeros, and without any spaces). I've used spaces as separators, as it's the simplest option, and the one typically used on the definitive statements themselves. I don't see any reason to artificially introduce something different. Some councils seem to have adjusted their numbering schemes in recent years, possibly as part of the process of creating digital mapping. I've seen an example where the parishes are given a numerical ID, and where a council has given each path a new number that is unique within the whole county. (This is Worcestershire, and at the same time, they've also split the paths up at every junction so that no path has two routes leaving a junction, i.e. a path always ends at the first junction of rights of way it comes to, and its continuation is now a separate new path. I think this may have something to do with geometries in GIS software.) I'm not sure what's best to do for for an overall format. I think we may probably have to consider things on a county by county basis, trying to keep things as consistent as possible. I would have thought for those using a traditional numbering we could agree on a single format. I'm not so sure about new variants though.
