[Talk-GB] Council Footpath data

Just a word of warning to double check the licensing terms before use. Many
councils' licensing is ambiguous in that they'll refer to the OGL then
state or link to the incompatible OS Open Data attribution terms.

Whilst it's a wonderful resource and I think Barry has done a great job,
the rowmaps site doesn't help with licensing clarity. There are quite a few
references to unverifiable private email communications where the licence
terms differ from the publicly available terms. Any mention of the OGL is
taken at face value even if when checked the licence is actually the OS
modified OGL ie. the incompatible OS Open Data licence! Perhaps most
seriously, rowmaps also relies on a misinterpretation of communication with
OS to suggest that OS Open Data licensed material is now automatically OGL3
licenced material.

All of this matters very little to most users of rowmaps but for OSM
purposes as we require ODBL compatibility we need greater clarity.

Over the coming months I'm hoping to individually clarify licensing with
all of the authorities which haven't explicitly, unambiguously and publicly
licensed their RoW data under OGL3 (and, yes, I know that's most of them).
I'll also try and get new or updated data where not currently available or
several years old. Ideally I'll get the authorities to include a clear
unambiguous licence on their websites but, failing that, I'll publish the
relevant communication online so that it is verifiable and we do at least
have certainty about the data currently available to us.

In the slightly longer term I think our aim needs to be to persuade all
authorities to proactively publish new versions of their data as open data,
rather than individuals having to individually badger authorities to update
their data. Under their Publication Schemes they should start doing this
automatically once information is supplied the first time, but it seems
that only a minority of authorities who have released data currently
publish it proactively.

Kind regards,
