Hi,
You accidentally added amenity=parking tag on one of the nodes, but not on the way itself. Could you please fix that by removing the tag from the node and putting it on the way.

The whole structure of the two Colleges is called Memorial Quadrangle and hence the multipolygon was created to avoid double naming.
I searched different sources about whether two touching outer members are valid an not, but only I could find is that two outer members touching in two nodes is valid: osm.wiki/Relation:multipolygon/validity

And inner members sharing a line segment is OK (touching inner rings): osm.wiki/Relation:multipolygon

I am a little confused why two outer segment could not do the same.

What tool does report this as an error?
As far as I know it is common practice to draw buildings that are touching as areas that have overlapping line segments (and it doesn't matter if it is a simple area or a multipolygon).

Hi EdSS,
Any reason for disconnecting these and all the other buildings?
This two buildings are physically attached without any passageway leading to the court. So far I see it as a candidate for revert.

I reverted your changeset.

Hi RD1,
thank you for contributing to OSM. However, I just realized that you made some disputable edits.
First of all you disconnected Morgan Lane at the intersection with Frontage Road and removed a road name from the West CAmpus entrance gate to the intersection with Morgan Lane. Do you think you can fix these errors?

Secondly you changed Frontage Road to residential road. Residential roads are typically with houses and as the name Frontage suggest this is going to be some higher class of highway (Unclassified or Tertiary).
Westcampus Drive can not be also not be residential road, but my guess it would be either service or unclassified.
I am not sure what were your thought behind such changes.
Best,
Martin

Ahoj plk42,
vdaka za prispievanie do OSM. Tag "name" sa vsak pouziva iba pre vlastne meno objektu (napr. Fontana mieru). Toto je iba opisny nazov.
Mohol by si ho ako aj ostatne "mena" fontan, jazierok atd. prosim ta odstranit?

Hello,
I would like to let you know that your changes completely disconnected several roads from Broadway, which made Whalley Avenue a dead end street. And also caused Broadway to be renamed to Dixwell Avenue.

This is a serious misconduct bordering with vandalism. I am writing this, because it not the first time such a thing happened on your side. OSM is a collaborative effort of many people and is used by many projects. Behavior like this has a detrimental effect on OSM data and community. Please, refrain from such edits in future.

I am reverting this whole changeset.

Hi Spanza and welcome to OSM. Thanks for tracing out those buildings, but I have to remind you that tag "landuse=residential" is used to mark residential areas and not the buildings themselves. Please replace the tags with "building=yes" or any appropriate combination from here building=*

Hi paulte, I changed tagging of your path to more appropriate highway=footway.

Hi potatodragon, I had to delete your paths in Edgerton Park because they were duplicate of already existing ways in that parks.

Hi Kaore,
waterway=stream is used to tag actual natural streams. What kind of object are you trying to edit? Can you please fix the error?

see: waterway=stream

This is an incorrect way how to tag an object. If there is a church in this building, you should place a new point/node in the centre of the building and use tags amenity=place_of_worship. The 'name' tag should contain its actual name and not a generic 'church'.
Could you please fix it?

See: amenity=place_of_worship

Hi Kaore,
are you sure there is a golf course at this place. I've been there multiple times and I haven't seen it.

When editing building footprints, please move the individual nodes of the existing object. Do not delete and re-draw the object. By deleting, all history and important tags are lost.
I had to revert your changeset.

Sorry had to revert your edit. The grass field exists on top of the undeground 41 Sachem building.

Hi RD1.
In your edit, you disconnected Argyle Street from Winchester Avenue and bunch of other service roads on the parking lot.
Was there a construction work? Because on the imagery everything looks connected.

I would be difficult to fix the data so I reverted your changesets 34742741 and 34736781.

And regarding your motivation, just remember that we don't map for the renderer, we map reality.

Hi RD1 and thanks for contributing to OSM.
I would like to ask you about purpose of your edits.

-You changed Morgan Lane type from "tertiary" to "residential". Any reason for that?
-You deleted a bridge on Morgan Lane over I95. The bridge is there and still functional.
-You deleted area that marked Yale West Campus. Reason?
-You deleted Heffeman Drive and replaced it with a unnamed service road. Are you sure this road does not have a name?
-You disconnected Entrances to West Campus from former Heffeman drive.
-You changed the type and removed the name of eastern part of West Campus Drive. Reason?
-You changed a piece of entrance road to tertiary way/360973798

According to this, Schwartzman Center opens in 2020.
Reverting.
