After writing my comment, I asked the question on the OpenStreetMap Belgium Matrix Chat. There have been a few replies so far.

Hello,

I see you tagged most buildings here as "apartment" buildings.

On the following set of pictures we took (https://www.mapillary.com/app/?pKey=237234365385252) it appears that most houses on Rue Van Kalck/Van Kalckstraat are single-family houses.

The purpose of this quest is StreetComplete was precisely to accurately distinguish between apartment buildings and ordinary houses. Putting inaccurate or incorrect information our database defeats this objective.

Would you mind having a second look at your changes?

Hello,

I don’t think that "Kiran shop" is a bank. It looks like you just filled an empty name on the map without looking at the type of shop.

I can fix it if you can tell me what you saw exactly here.

Thanks.

Hello.

In this changeset, you removed two buildings that appear to be still there (in Bing Maps Aerial which iD claims you have been using, and in Mapbox Satellite too).
way/88006980/history and way/177545021/history

Were those buildings razed recently?

If that is the case, it is adviseable to say so in the changeset title. When users with few contributions start deleting buildings or landmarks and hide their changes under a vague "Some minor changes" title, you could easily understand that it raises suspicions.

Would you mind providing some more info please?

Hello,

This object is a bit weird:
relation/15978161

You created an invalid multipolygon with two adjacent outer areas, and gave it a dual tagging that says: "This is both a social facility AND a car park."

The problem is that nothing will be rendered or searched properly.

I suggest you examine this again. Make it two contiguous areas, one for the car park and one for the woonzorgcentrum.

Hope this helps.

Hello,
If you want to draw houses and buildings, you might be interested to use another background when editing.
Never trace buildings on aerial imagery. Switch the background to use "Digitaal Vlaanderen GRB" (or "AIV Flanders GRB" depending on the software version you are using), and there you will have a good reference.
Hope this helps.

The "convention" is just a single wiki page created about 3 months ago where most of the text comes from a single contributor.
osm.wiki/w/index.php?title=Key:campus&action=history

Naming convention for university sites spread over several places is worth discussing within the community.

Hello,

It looks like you did not just "add info about the campus"… but changed the main name. And I don’t believe this i correct here.

ULB has several campuses. The usual tagging convention would be to name them like this "Université libre de Bruxelles – Campus du Solbosch". (We did this for VUB, Odisee and others; note the "en dash" separator in the middle.)

It might be a good idea to review the other campuses and apply a standard convention for them. If you feel like doing it, fine, otherwise I’ll put it to my list of things to do.

Cheers.

Hi.
This object looks quite suspicious too:
way/1181727857
Really a full-scale hospital? Isn’t that rather a clinic?
Also, the address you typed for that place does not match any known street name around.
Cheers

@ivanbranco: The changeset does not replace "crossing:markings" but "crossing:marking" (notice the singular form).

Hello,

I want to alert you there are several problems with this edit.

1) The operator tag is not meant to add the name of a private individual. We write the names of businesses, not business owners.

2) The street name is not written correctly. The street is named "Allée John-Fitzgerald Kennedy" on the map, you should write it the same way on addresses, otherwise it just makes the database incoherent.

3) Phone numbers should use international format. No "071" please → use "+32 71"

4) Information such as "leur showroom était situé à Montigny-Le-Tilleul nommée Ets Vandevoorde" should not be put to the changeset comment. If you want to convey historical information, it could possibly find its way into the "description" tag. Or start_date=1979 if you feel the age of the company is important to assess its reputation. This makes much more sense than those promotional texts you are relentlessly typing to describe your changes. Please refrain from misusing changeset comments to put advertising-like texts.

Please take some time reading changeset comments that are being sent to you. They serve a purpose: helping you to make better contributions in the future.

You have been ignoring every comment so far. Replies are appreciated. You can reply in any language if that makes it easier for you.

Hello,

What does "length=0" mean?

Again, if you keep using the iD editor for such items, please type tags directly and ignore the silly presets entirely.

Normally, a private pool in a garden should only have those tags:
access=private
leisure=swimming_pool
swimming_pool=outdoor

Hello,

Tags like "swimming_pool=inground" have been designed to be used as additional tags on facilities, e.g. to tag a hotel and mention there is an inground swimming-pool.

Please use "swimming_pool=outdoor" for private swimming pools in gardens.

Bonjou,

"Venelle au Qautre noeuds", c'est une orthographe corrigée ? Je crois voir des fautes d’orthographe.

Existe-t-il un document officiel avec le nom de ces venelles svp ?

Hello,

Is the "." (period) characted inside a key allowed? The wiki considers it as discouraged and it is usually flagged as incorrect by Osmose and others, this is the reason why I changed it into "delivery:takeaway_com" in the previous version.

I won’t make a fuss about it but having clear standards about how to deal with such cases will save us an edit war. :-)

Have a nice day.

Perfect, thanks.

Hello,

I suggest merging those 3 ways. Creating 3 small ways with the same tags do not make sense and make it error-prone for future mappers who will work here.

way/1180183772
way/1180183773
way/1180183774

Hello,

There are two houses with housenumber 31 now. :-(

This one is labelled 31, do you know if the number should be dropped here?
way/224606107

Hello,

We’d rather put it as a separate node. Fixed by changeset/137027133

OK, thanks.
I will clean up the other tags because the temporary tag is still there.
Have a nice day.
