Hi again.
Please consider twice before accepting auto-validations. Many are incorrect (esp. iD) or false-positives.

Hi
has no implication of access rights. Those are dealt with with 'access' tags.
There's no requirement for a spearate tag within schools. From the wiki:
"...but sometimes also part of colleges / companies, or commercially operated."
landuse=recreation_ground

If your "work is based on what you see at the time" You'd have seen this in the pavement & not erroneously removed sections from the route relation.

No. It was "for Cotswold Way sequence route - attempt the first" which is meaningless. Your follow up explanation is equally incomprehensible.

1. Anybody has "authority" to query another's OSM contributions. OSM has set up numerous channels in which to specifically do so.

2. I've no idea what you're talking about. Who's assuming?

3. Nope, still not clear. Please try again.

Have you considered why you receive so many criticizing changeset comments?

Hi
When splitting a station from a way & it's close to a join in that way, could you unstitch the way so the existing station node can be move whilst retaining its history which many find a useful asset in OSM. Ta

Hi again
FYI I've map railway=station as separate nodes to they can be positioned more accurately. There can be multiple buildings (tagged as building=train_station) which can be located quite a distance from platforms.

node/502562799
Does this need a highway=bus tag or is it a duplicate of the same named one here:
node/412811758

Hi
All railway stations are mapped. Please don't duplicate them in train station buildings

Unsure.
NERC If you mean Natural Environment Research Council, I'm unclear as to the relevance.
What does NSG mean?
Can you tell me which OOC OS maps, or definitive statements shows these definitions.
By your own statement (& trail's) unclassified_highway appears to be a classification rather than a designation of a right of way.
As an example could you explain where you got the designation for way/42959405

Hi
The convention is to not add 'Rail Station' to railway=station name tags.

As it's only one entity just revert the tags .

Hi
What source informed you they are municipally maintained?

Hi
Are you sure? Has it been reopened?
Avon Valley Trail isn't the path's name. It's the name of just one route which can pass along the way. See the attached route relations.

Hi
What is a unclassified_highway designation?

Hi
FYI railway=station already exists. There mapped as nodes separate from building=train_station

Hi
Do you have local knowledge for these edits?
It's unclear from your ambiguous comment "I have fixed a mistake" Please be more detailed, here & when closing a note.

Hi
1a I've no idea if it's private
1b If you want to
2 If you want to
3 I didn't add those tags. I copied them from one way to another
4a If you want to
4b If you want to add a barrier, fine, but are you sure it requires one
5 Not convinced it's maintained grass, but if you want to.
6 If you want to.
7 If you want to
8 On Bing it's mostly bare earth & there's clearly livestock.
9a Rubbish.
9b If you want to.

Open, as in the area where the activities are performed are not obstructed.
the 'general recreation' has no implication of ownership. Read the second sentence.

Have a read of leisure=pitch

As can be seen in aerial imagery the Triangle Field has multiple pitches which should be mapped individually.

Hi
Welcome to OSM
Could you provide more detailed changeset comments than 'more information on area'. It helps those of us who validate amendments.

way/405862099
amenity is the correct tag for a school boundary. building-school goes on the individual building within the school

Same point here

Hi
Cricket pitches aren't square & don't include a pavilion. This is a recreation ground.
