I've received a tweet drawing my attention to a thread with the subject "Local Authority rights of way information". I wasn't receiving the emails for this list and I can't see a way of replying to an e-mail if you didn't receive it.  So I guess I'm starting a new thread which is annoying.

If you go to:
   http://www.rowmaps.com/datasets
and then go to the pages for each of North Lincolnshire, Oldham, Portsmouth, Salford, Wigan and the Wirral, you'll see that these datasets are released with the OGL.

The datasets for most of the other local authorities were released under terms equivalent to the OS OpenData Licence.  When I e-mailed the Ordnance Survey about the local authorities that had, during the last few years, successfully obtained an exemption from the Public Sector Mapping Agreement and released their data under terms equivalent to the OS OpenData Licence, Richard Mortara [Public Sector Contracts Manager, Ordnance Survey] replied: "All data exempted by Ordnance Survey is now covered by the Open Government Licence (OGL), which superseded its own OS OpenData licence in April 2015."

Actually the website www.rowmaps.com does not yet provide data for Hull.

As far as East Yorkshire is concerned, I received an e-mail from Judith Rockliff [Engineer (Definitive Map), Asset Strategy, Planning and Economic Regeneration, East Riding of Yorkshire Council] on 10th January 2013 that said "I am pleased to be able to tell you that a request from East Riding of Yorkshire Council for a derived data exemption in relation to its Public Rights of Way (PRoW) datasets has now been approved. As a consequence, the terms equivalent to OS OpenData (see http://www.ordnancesurvey.co.uk/oswebsite/opendata/docs/os-opendata-licence.pdf ) may now also be applied to the dataset being released."

When I requested an update in 2014, I received a reply from Gordon Grimley [Assistant Engineer (Definitive Map), Asset Strategy (AS 67), Planning and Economic Regeneration, East Riding of Yorkshire Council] on 27th February 2014 saying "Attached is the most recent copy of the shapefile.  All the same licences etc apply."

I don't normally ignore e-mails.  So maybe your e-mail didn't get to me.

Although I don't do the hard grind of adding to OSM, it has always been my view that's it's irrelevant as to what licence the data has been released with.  As others have pointed out in this thread, the data from www.rowmaps.com can best be used to identify a PROW that needs surveying: what's in the data may be quite different from what happens on the ground.  And this disclaimer that www.rowmaps.com shows alongside any map is also appropriate: "An authority's Definitive Map is the authoritative source of their rights of way. The details of the public rights of way network contained in an authority's data are for information only, and are an interpretation of the Definitive Map, not the Definitive Map itself, and should not be relied on for determining the position or alignment of any public right of way. For legal purposes, an authority's data does not replace their Definitive Map. And changes may have been made to the Definitive Map that are not included in their data."
