Hi
When splitting buildings to specifies levels please be aware of the defining tags.
There aren't two museums.

changeset/90603390#map=19/51.38666/-2.36693

I understand there are ways with relations to specify individual internal parts of a building..

I've reverted your changesets because the data you added is incorrect. Please refrain from doing similar in the future.

Hi Paddy
https://osmlab.github.io/osm-deep-history/#/way/680220597

You appear to have greens at both ends of the fairway. Should some be tees?

Hi
There's no need to create a multi polygon, a simple closed way would suffice
relation/11273572

Hi
Which is it:
way/813722220
way/818915016

Hi
To check, is it meant to be this shape?

You added the tag which defines a railway station (railway=station) to the building, This is incorrect.

I've corrected it for you.

All UK railway stations already are mapped. Please don't add duplicates.

Please don't delete tags without understanding why.

What is this?

Hi
Could you refrain from duplicating tags (ref:crs) on relations which are already on ways & nodes. It only causes confusion & errors.

When detaching railway=station tags from railway lines could you move them instead of deleting & recreating anew. The edited history of data is very useful.

Unsure if you're adding them, but entities such as railway lines, ATMs. bike racks, bus stops, cafes etc aren't required. (Actually I think there's a fair argument stop areas & PTv2 isn't required at all. It's all just duplication & collections.)

Hi
Could you delete the school tags & move it back to where it was previously please. There is already a school mapped as a polygon way.

Have a look at this to see how to tag recycled phone boxes

Hi
There is already a railway=station tag.
GB stations are all mapped (as nodes).

Great.

Ah, OK. I don't remember it going that way, but it was a few years a go.
Do you want to update it, putting the gates in?

Sorry, which path?

I'm pretty sure this isn't the train station building. Could it be the surrounding one?

Hi
You've added another duplicate railway station which I've now deleted.

Please be aware all UK stations are already mapped. You can often find the node between the tracks at the midpoint of the platforms.

You made it inaccurate again. These are not a public_transport=station.
