Kedves kalu1820!
Honnan ered a Közti-park elnevezés? Az interneten sehol sem találok ilyesmit, és a helyiek sem szokták így emlegetni a Dugonics tér és Kölcsey utca közötti háztömb belsejét.
Kösz!

Can you specify more exactly where you can find it on the wiki site? It is a bit long…

Anyway, inside a multipolygon is not needed any additional relation. One or more simple ways are fairly enough.

Look e.g. here:
• relation/1775846 or
• relation/1775847

They consist of two ways and that's it. No additional multipolygon inside the multipolygon.

No, definitely not.

Now, you have a multipolygon with another multipolygon as an inner member. This is absolutely not necessary and just makes things more complicated.

The solution is to have a multipolygon where the inner member are simple ways (areas).

For more information:
osm.wiki/Relation:multipolygon

(Or just look some multipolygons on OSM.)

E.g. these are multipolygon relations with one and only member:

relation/19857249

relation/19857252

They can stay alone as simple features (ways) whithout making them relations.

OK, no problem ;-)

Dear Lola Fox,

swimming pools can simply stay alone as polygons; it is absolutely not needed to create relations with only one members e.g. from swimming pools (or from any other feature).

Relations are made to relate two or more features.

Cheers

Ezek nekem mindig homályosak, mindenesetre most kikalapáltam.

Actually not, it is not signposted, there is just a website to it that you can see on the relation itself:
