[Brief historical footnote: P1 only ever included it on its "public
footpath" and "bridleway" presets (and note that the former was indeed
"public footpath" rather than "footpath" or "footway" or anything). I think
the original intention was that other people might contribute tag presets
for their own countries' path systems, but this was all about six years ago
when I was still young and green enough to think that people might ever
contribute tag presets. I'm not sure I ever thought that foot=yes meant
"this is a legally declared public footpath", I've always understood it to
have the second meaning ("public right of way for people on foot").]

As you were...

cheers

It rarely ends up in exactly the same place - when I'm doing these
node replacements I take time to remodel junctions, improve curves and
so on. The contribution is my own, not an obfuscation of history. The
"O" keypress is just a little labour saving, not a "charade".

Because that would be incorrect. The odbl=clean is not a "I somehow
assert that I would do the same, therefore ignore the IPR record". The
tag is to indicate "where their contribution have "washed out" and
where the contributor(s) in question cannot reasonably claim any
rights to the current feature"[1] - i.e. subsequent edits have
entirely overwritten any IPR in the non-acceptor's contributions. It's
easy to see that the tag is therefore completely inappropriate for
adding to any v1 objects, for a start.

Of course, since the odbl=clean tag is so widely misinterpreted, by
you and seemingly by many others, the tag becomes as meaningless as
foot=yes[2] . It wouldn't actually make any difference during a
changeover anyway - that's the whole point of the tag, after all, to
indicate that even if you removed every conceivable trace of
non-accepting edits from this feature, then end result would be the
same - so there seems little point in adding it. So it's a bizarre tag
- when misunderstood it's applied incorrectly, and when understood
fully it barely makes sense to use it anyway.

Cheers,
Andy

it was ambiguously confused with a general legal right of walking
(e.g. on a bridleway). Automatic inclusion on all footpaths of any
type by potlatch1 for a number of years, it became effectively
meaningless as a designator for Public Footpaths, and a new tag
(designation=public_footpath) was eventually created.

If you reposition the new node in same place as the old one, this hasn't really
achieved anything.  At best, it has obscured the history a bit so it's no longer
quite so clear that the node was originally added by a CT-decliner.

Rather than going through this charade why not just add odbl=clean to the node?

Using Potlatch 2, select the junction node and press "O". This deletes
the node and attaches a new node to the cursor - you need to click to
position it. Doing it this way sorts out all the ways for you.

OSMI makes an effort to highlight as problematic only those nodes where 
the removal of decliner content will make a meaningful difference. It 
should treat the created_by tag as "harmless", i.e. these objects should 
just appear in yellow which is not cause for concern.


In fact I wonder if I should ditch the "harmless" layer altogehter and 
have nothing that is coloured yellow, it seems to confuse people more 
than necessary. The idea behind the yellow "harmless" thing was to 
signal to the mapper "this object has been touched by a decliner but is 
still considered ok, you don't have to remap it". I did that hoping that 
people would occasionally check if OSMI does the right thing ;) but 
maybe the time of the yellow stuff is over.


Bye
Frederik

I don't think so :-/

I'd mark them as odbl=clean (or whatever that tag was).
