Unless you've been given permission by the copyright holder to make use of a map like that, then it's off-limits for use in OSM. The map at https://www.lancashire.gov.uk/roads-parking-and-travel/public-rights-of-way/public-rights-of-way-map/ is currently not working for me, but is does say "(c) Crown copyright and database rights 2020 Ordnance Survey 100023320" below it. It's likely that it was showing lines for Rights of Way on top of an Ordnance Survey base map -- in which case it certainly couldn't be used for OSM mapping. You might be able to get permission to use the overlay lines, but you'd have to detach them from the base map before using them. Otherwise you might be inferring location details from the OS base map. Ordnance Survey are quite strict on what they consider to be derived data from their maps, so OSM needs to be very careful around them. What we do have permission to use in OSM is the raw GIS files from Lancashire. As already noted, these contain both the parish IDs and names. It's up to whoever renders them what to show as labels. Hopefully we can agree on a prow_ref format here, and then any tool authors will follow that in what they display to mappers. > It is then complicated that other sources use an mix of formats.

Both myself (who runs PRoW Comparison tools) and Nick (who runs MapThe Paths) intend to ensure our tools show whatever prow_ref format is agreed. So that should be two common sources of data for mappers to use.
