Hello Robert, I wasn't familiar with the situation in Dorset but MapThePaths uses the 'SE 4/22' scheme (actually it appears as 'SE 4 22') so if people want to use MTP as a source for prow_refs, then that would be the format to use. In terms of how I arrive at the references, I sourced the data from the rowmaps site and applied a script which looked for a particular field (I forget its name) in the rowmaps data. This is done consistently across all counties. I don't really mind too much what people use to be honest, obviously something like 'Studland FP 1' or similar would be more descriptive, but would require an extra step to look up the parish name. Maybe we should develop some sort of (crowd-sourced?) service which looks up parishes based on parish codes to allow easy contribution of descriptive prow_refs? On the other hand some counties do not use parish refs at all in hhe number, though they do mention them in the full ref (e.g. FERNHURST 1254). The Chichester district of West Sussex (not OGL, by the way - unfortunately from my POV as it's an area I'm interested in) appears to use a simple number for all PROW refs, ranging from about 1-3500. This is not consistent in a given parish, e.g. numbers between 1200-1299 appear to be spread between Fernhurst, Lynchmere and Milland parishes.

In particular, I've been looking at the data from Dorset. I've hit a small issue though, in that the council uses two different formats for their Right of Way Numbers. We really need to just select one for the county in order to be consistent in OSM. One format has a parish code followed by a slash and then the route number within the parish (e.g. "SE4/22" for path number 22 in Affpuddle and Turnerspuddle parish). The other would be to use the full parish name, right of way type, and number. I asked their Definitive Map officer about this and got the response: "Both systems are used in parallel. For mapping (where the status and parish are obvious) and for internal use, we use the numbering system, but when reporting to Committee members or members of the public who will not be familiar with the numbering system, we name the parish and describe the status. Our sealed statements are listed by named parish, status and route number. Our working statement spreadsheet uses parish number, status and route number." The "SE4/22" style numbers are what are used on Dorset Council's own online map at https://www.dorsetcouncil.gov.uk/countryside-coast-parks/rights-of-way/rights-of-way-map-where-to-walk-ride-or-cycle.aspx . Currently in OSM we have about 394km of routes in Dorset using this style in the prow_ref tag, and another 98km using this style with a space instead of the slash. That a total of around 492km based on the parish codes and numbers. Conversely, there's only around 125km of routes in Dorset that have a prow_ref tag that includes a parish name. Based on this, my preference would be to standardise on the "SE4/22" style format for the prow_ref in Dorset, and convert any other instances found to this. What does everyone else think? I'll invite Nick Whitelegg (who developed the "map the paths" site) and also a few mappers who've made significant contributions to Dorset PRoW's in OSM to this thread to get their input too.
