I twice asked Д-р Стефанов for their preference on under which name they would like to be mapped (using the website contact form) but got no reply. Did you change your mind already? Or shall I ask the OSM community for their opinion?

I'm mainly worried about the precedent it will create. If you add these links, someone else will like to add links to other airport database websites, and them maybe review websites for airports, and before we know it we will have a very long list of weblinks for airports, buildings, restaurants, hotels, schools, ... See also here https://community.openstreetmap.org/t/add-key-to-link-third-party-website-with-pictures-menus-description-or-reviews-about-pois/100390 for a similar discussion

Please don't. The database you are linking to does not contain useful information that isn't already in the wikipedia page. Only the frequencies mentioned might be useful for professionals and could be added to the infrastructure mapped on OSM. If you disagree, I will open a discussion on the OSM community forum

Hi, I saw you are adding links to an airport database for this airport and many more. I don't think this is a good idea: should we then also add links to a city database for all cities in the world, a link to a school database for all schools in the world, etc.? There is already a link to wikidata and a wikipedia page: I think that should be enough.

It's good to check. When I see a (service) road with motor_vehicle=no, I'm wondering why the road is there at all if no motor vehicles are allowed to use it... or maybe it's not a road but a path, pedestrian_street, etc.? It's been along time ago since I was there so I don't remember if there were any signs.

Completely forbidden, or are some allowed (delivery, for instance)? Then motor_vehicle=private / delivery might be better.

Yes, but is abandoned:building=construction a valid tag? It describes it well...

I don't remember why I added it, so if you think it's wrong, remove it

Hi, are you sure that that way is not part of ul. Методи Андонов? I tried searching for documentation but only found that there is such a street but not where exactly it is. I think there are no street name signs there at all. If you're sure it's an unnamed street, please remove the way from the Методи Андонов road route relation too.
Pozdravi, Richard

I've written to them today, let's wait for their answer before making any more changes

Ah yes, maybe a шивачка. I've only seen it with the doors closed, and then there's nothing to see.

Good point, I will ask

Slogans can also be copyrighted. I think the best is to ask the company how they want to be displayed on OSM. Will you ask them or shall I?

Hi Mitko, why did you add this shop? I didn't see anything looking like a shop there, only a garage. There might be a shop in the garage, but the doors were closed this afternoon

The shops I know had both Д-р Стефанов and Нечовеши магазин on the shopfront. If they removed Д-р Стефанов, that must be recent. Нечовеши магазин sounds more like an advertising slogan and a description than a name.

I'm sorry but I don't think your changes are correct. According to https://zoomagazin.eu/bg/za-nas the chain is called Верига зоомагазини "Д-р Стефанов" There is also a brand preset for the chain with the name Д-р Стефанов Please revert your edits

Sorry, my mistake, now corrected

Hello and welcome to OpenStreetMap!
Thanks for adding the restaurant. However you must have used an old version of the map because I also added that restaurant a month ago. I will remove your duplicate and add facebook link and phone nr to mine.

Good idea to map the sidewalk! Thanks

I can't find out what you changed here... Walking from the south on one of the paths, you first step down on the road (raised kerb), then cross it (informal crossing because there are no markings on the road, no lowered kerbs, etc.), step up on the sidewalk on the other side (raised kerb again) and then go down from the sidewalk down the steps. I think it was correctly mapped. See https://maps.app.goo.gl/R63iZ6CgHnRk1rH4A
