I find your mass change of one tag to another troublesome. Since both spellings (color/colour) are correct, I assume your changes are based only on forcing uniformity. As much as that is a useful goal, the OSM community has for a long time expressed that it values flexibility and mutability of the tags over the perfect conformity of the tags.
Without communicating with the OSM community at large, it is not possible to know if the “color” tags were tagging mistakes or a user’s preferred tagging scheme. If they were a preferred tagging scheme, then a conversation among the OSM community needs to occur to decide if we live with both spellings or if, as a group, we override the few editors, who prefer “color”, and force the change to “colour” only. Your actions make it appear that you have misinterpreted “depreciated” and “discouraged”, which is used as heavy social pressure and not to mean “these are mistakes that no one has yet taken the time to fix”.

The wiki for building:roof:shape very explicitly asks you not to do what you've done here (and with other tags).

Here is a link to the page:
osm.wiki/Key:building:roof:shape?uselang=en

Here is the warning:
"Under no circumstances should you (semi-)automatically change “deprecated” tags to something else in the database on a large scale without conforming to the Automated Edits code of conduct. Any such change will be reverted."

"shall we put a horse=yes tag onto all city stairs too?"
Yes. If it is legal then yes.

The concerns you are expressing appears to be a routing program issue and not an OSM database issues. It is reasonable to expect a trip routing program identifies stairs (independent of legal restrictions) as a way type that a bicycle rider would either want to avoid or would wish to be warned about, ahead of time. A routing program that only routes using access tags is not only a poorly designed program but also dangerous one. The same logic applies to surface types.

When the access tag is used to apply a subjective usability, it becomes impossible for the routing program or the rider to make their own choice on the most appropriate/desired route to take, even when that legal route is difficult, dangerous, or a dismount area. Different riders have different needs. Gravel riders, distance riders, daily riders, etc. all have different routing needs/wants. If a set of stairs, a short gravel path, or a steep grade are legally accessed by bicycles yet is either marked bike=no (or is default no due to way type) then we rob the routing program from accuracy/flexibility and we rob the rider from knowing their legal rights and we steal their personal autonomy.

On a personal note, I use OSMAND and it gives me the following cycle routing options; “no unpaved roads”/”no stairs”/”avoid footways”/”no cobblestone or sett”. Bad access tags directly affects OSMAND’s ability to route me in a way that I’m asking it too.

With all do respect of the deceased, what does Brian Fairweather's accident have to do with access tags in OSM? From my understand, Mr. Fairweather’s accident was the result of not being familiar with the route and low visibility of a set of stairs. I don't know the details, was Mr. Fairweather’s death a result of an erroneously instruction, by a routing program, to ride down the stairs?

You might be correct about the roadway being used primarily for the light rail station, I can only speak from my personal experiance.
What I have noticed, the overwhelming majority of light rail riders access the station from either foot traffic (from the U-District/Montlake) or from the transit depot, across the street.
I believe the use of the sports complex will increase dramatically once UW is fully open and has a full student body on campus.
That's just my opinion though.

Hi Kurt Pattyn,

It looks like you might have gotten confused with the phone number formatting directions, just like I did. Those directions are as clear as mud. This is what I've figured out.

US phone number format is:
[ +1 234 567 8910 ]
(This is the OSM preferred international formatting)

<Below is extra information. Don't let it confuse you>

US numbers can also take the following format:
[ +1-234-567-8910 ]
(This is a valid formatting yet I tend to stick with the other style as it matches the international style).

I don't think the OSM community has decided on the correct way to add extension numbers. However, I often see extensions listed as:
[ +1 234 567 8910 ext11 ]

In the OSM wiki, under "contact:phone", the phone number format is shown as
[ +1 234 567-8910 ].
So, for the moment, it's the third "correct" format. I don't think this format is going to stick around though.

I hope this helps.

I believe what you have indicated as tunnel=building_passage are simply covered=yes. They appear to be extensions of the roof and only have one wall (open on the side opposite the building).

FYI: access tags are for legal access not usability.

As far as I know, the University is O.K. with bicycles along this way/steps. Though, I think it is safe to say that the University isn't O.K. with riding a bike up or down the stairs. Therefore, maybe "access=dismount" might be the appropriate tag.

I disagree with the change from service to unclassified road. Mainly, but not exclusively because of the usage of unclassified, as described in the wiki to be: "highway=unclassified is used for minor public roads". This is not a public road. It is a way managed by the University and not by the City. Additionally, these ways are part of a network of ways which primarily service the parking areas of the University's sports facilities. Service to the light rail station is secondary. Maybe I'm incorrect. What do you think?

I just had a changeset interaction with a German(?) regarding the name:etymology:wikidata tag. They mentioned the same thing you did. So, being a good sport, I looked to see if I could add any map data.

As a matter of fact, I had heard of the project before. I believe, I first heard of the project from the Geochicas talk during the 2018 State of the Map, presented by Celine Jacquin. https://www.youtube.com/watch?v=rl9HZKyKWWE

I’m not a big fan of the project as a whole. That being said, I hope the project achieves the social change that many of the supporters believe it will. Good luck and happy mapping.

A "feature" in Vespucci? Good to know. I don't use Vespucci often but I'll keep my eye out for that issue next time I do. Thanks.

My guess is that there is some site blue print plans, for the past Mercer Court construction project, that has the answer. There should be a UW department that would know. I might toss a few emails out and see what I find. Thanks for your effort.

Fast work, sir. Looks good on my end, as well. Happy mapping.

Wouldn't these roads fall under the "forestry" usage for highway=track?
osm.wiki/Tag:highway%3Dtrack

Has the definition for "track" changed? I know there was a lot of highway=track talk in Feb, Mar, and April. I don't know if you noticed that.

It looks like you mistakenly dragged the traffic circle into the neighbourhood before uploading.

By chance, do you know if that section of road is (still) called Adams Road or is it the end of Cowlitz Road Northeast? Seattle GIS doesn't label that section specifically. "Tiger Roads 2014" map layer (JOSM) shows that section to be Cowlitz. Google Street View (reference only) does not show a street sign, at the intersection with NE 40th st, as far back as 2008 . The UW campus map doesn't label that section but does label Cowlitz Road NE as NE Cowlitz Road so UW is playing fast and loose with street names. There is an Adams Lane between Mercer Court and Stevens Court and there was a road leading to a parking lot on the west side of Mercer Court back in 2008 (but there is no street sign). Maybe the old (now removed) road was Adams Road? I can't tell if this small section is now Cowlitz Road NE or an unsigned Adams Road.

Please revert this change.

This is a fake park created on google maps, by a number University of Washington Computer Science students. Looking at whom originally posted reviews on Google Maps and on the fackbook page, I suspect the "park" was named after one of the women in the friend group.
The city of Seattle has no record of this park. This grass area is just one of a couple dozen large grass covered center medians, which run the entire length of Northeast Ravenna Boulevard. The "park" has no park signs. There are no park amenities such as benches, trash cans, etc. The first mention of this area as "Olga Park" starts in 2018 with this google listing, a facebook page, a website, and a instagram page.
I informed Google about this over a year ago. The windows of my apartment over look this "park".
Since the morning of the murder, I have sent correction emails to media yet they seem to trust Google Maps to all other sources even after been informed of the college student's prank.

As a side note: Google Maps "Local Guide" have shown themselves to be fairly worthless since their reviews contain nearly zero factual information about this "park".

Do you have a source that connects Homer Street in Boston, US with Homer from Greece? Is it possible that Homer street, in Boston, US, was named after Winslow Homer, a famous artist from Boston?
https://en.wikipedia.org/wiki/Winslow_Homer

I think your automated edits might be introducing bad data. I have only looked at the three US changes, which I've commented on (two changesets), and 2 out of 3 appear to be incorrect in some way.

How do you know they are named after Ernest Hemingway?
The Marion (Cedar Rapids) location is a reasonable guess since the surrounding streets appear to be other authors but guessing is the weakest form of ground truth.
osm.org/way/367521921#map=12/42.0755/-91.5803
I disagree with the Redding location. I do not believe that a non -local can know if that street is named after Ernest Hemingway. The area appears to be a generic housing development with random generic American street names. They often do not refer to anything specific. If it was named after an actual person, it could as easily be a local family with the last name Hemingway or Ernest Hemingway's son, Jack, who was a conservationist along the west coast or either of the famous granddaughters Mariel & Margaux Hemingway.

Did you intended to include two US streets?

Is there a reason you changed a correctly formatted phone number and made it non-standard?
+1 425 223 5798 - only spaces is the preferred OSM format.
+1-425-223-5798 - only '-' is an alternative for us Americans.
