While Rob's OSM Stuff is technically third-party, it's the best tool we have to try to get the UK Public Rights of Way mapped and correctly tagged, and to find missing ones.  If tags are removed, we will be going backwards.

The wiki demonstrates adding "foot=designated" to all PRoWs: public footpaths, public bridleways, byways and restricted byways.

https://wiki.openstreetmap.org/wiki/Access_provisions_in_the_United_Kingdom#Byways

https://wiki.openstreetmap.org/wiki/Access_provisions_in_the_United_Kingdom#Restricted_byways

Therefore, ideally they will contain the below tags.

Public footpaths:
designation=public_footpath
foot=designated
highway=*
prow_ref=*
surface=*

Public bridleways:
bicycle=designated
designation=public_bridleway
foot=designated
highway=*
horse=designated
prow_ref=*
surface=*

Byways:
bicycle=designated
designation=byway_open_to_all_traffic
foot=designated
highway=*
horse=designated
prow_ref=*
surface=*
vehicle=yes

Restricted byways:
bicycle=designated
designation=restricted_byway
foot=designated
highway=*
horse=designated
motor_vehicle=no
prow_ref=*
surface=*
vehicle=yes
