Hello meongseolin,

I changed the admin level of Somaliland from 2 to 3 previously, so I can answer this.

The way that disputed territories are handled in OSM can be seen at https://osmfoundation.org/w/images/d/d8/DisputedTerritoriesInformation.pdf . When we last discussed the status of Somaliland, there were things in its favour (largely economically independent from Somalia) and things against (recognised as independent by almost no-one internationally).

Before we make top-level changes to things like this, it’s important to discuss them - https://community.openstreetmap.org/c/general/38/none would be a good place to do that.

Best Regards,
Andy (from OSM's Data Working Group)
