Thanks for contributing to OSM! It would be helpful if your changeset description were more specific about what you changed and why. For example, "Added an apartment office, referencing the property management website." See more info here: osm.wiki/Good_changeset_comments

Hi, please see the comment on your previous changeset at changeset/144810285 . The SJSU relation is only for the main campus, not satellite campuses or off-campus facilities.

wikidata=* is to say that the tagged object is exactly the same as the object on Wikidata. I don't think it's possible for an initiative to exist physically, and I also don't think this traffic sign is where they headquarter. However, the sign does have Solar America Cities branding on it, even though Solar America Cities is not commercial. brand:wikidata was correct.

You can read about building parts here: osm.wiki/Simple_3D_Buildings They're used for representing buildings in 3D, do require both the building part and outline to be mapped, and sometimes don't directly correspond to physical building components.

Hi, individual trees should only be mapped with natural=tree on nodes, not natural=wood areas. The latter is only for forests.

Hello! Please only add objects that currently exist to OpenStreetMap. Read more about the policy here: osm.wiki/Good_practice#Don't_map_historic_events_and_historic_features Efforts to map historical features are greatly appreciated by the OpenHistoricalMap project however! https://www.openhistoricalmap.org

Do not change tags just so that an object renders or looks a certain way. OSM needs to be able to provide reliable data for everybody, not just the map on osm.org. osm.wiki/Tagging_for_the_renderer

Yes, information from on the ground is always preferred, I just thought I'd point it out since you were referencing the tax assessor so often.

To be clear, the tax assessor isn't an authoritative source on street names. That would be the org which named them, which would be the city's department of transportation.

I just fixed a mistake where each building was labeled as a residential land use/apartment complex, instead of a building, and building=apartments is the correct tag for condo buildings: building=apartments

Remember that validator warnings are just that, warnings. They're there to tell you that you might have made a mistake while mapping, not that something is mapped "wrong."

flag:type=* says that "regional" is correct to refer to states, "state" is not.

Welcome to OSM and thanks for your contribution! Informal names used only by the local community might better go in the "loc_name" tag, so that the proper name can stay in the "name" tag. Or, for the other way around, if the official name is rarely used by anyone, it can go in the "official_name" tag. Read more here: osm.wiki/Names

Hi! If you don't know the actual size and shape of a tee box, please just add a single node, rather than an imaginary circle. I've fixed the ones in this course in changeset/144804585 Thanks!

layer=* is not a physical descriptor, just a hint to the renderer for what order to draw features. Therefore it applies to the building, but not the associated amenity. It's fine to make gas stations a separate POI, but it wasn't wrong before either.

If both names are signed, it's better to list both than to arbitrarily prefer one.

To be clear, vehicle capacity alone doesn't determine the class of road. Connectivity is more important. See osm.wiki/United_States/2021_Highway_Classification_Guidance#Classification Though I don't know the specific area well so I can't say for sure whether Tantau is more or less important than Vallco or Pruneridge.

Please use the changeset description to describe what you changed and why. For example, "Added traffic light to intersection." See more examples here: osm.wiki/Good_changeset_comments

Thanks!
