I see, thanks for clarifying.

What you are looking at is parcel/plot/property information (Īpašuma nosaukums), but not address data. So using `addr:` tags would be incorrect, because that's not the address. (Also I should note that an automated bot in Latvia imports addresses, so these sort of points not in official data would get deleted). I am not aware of OSM having tags for such "raw" cadaster data.

OSM generally maps what is on the ground, so there usually should be something here to warrant naming it on a public map. Address points by themselves are the rare exception. As there are literally hundreds of thousands of plots in Latvia and many have property names, we don't really add their "names" by themselves because usually those names are only known to the owners and have no significance for the map. Unless the property is an isolated dwelling or has a proper address.

An example of address point might be: https://www.openstreetmap.org/node/2073655064

There isn't any rule that this shouldn't be mapped but I feel that it's probably not the sort of information we would want to map. If you want to add many more of these, it's probably best to discuss it with the community first.

Cheers
