@zverik Level0 was a great, easy way for sites (like townlands.ie) to do simple “imports”/“mechanical edits”. I had the tags (in level0 format) which people could add to objects & a link to level0 edit URL. Mappers could open in new tab and paste the tags. Done. Edits in a few clicks.
Certain versions of this could be done with @MapRoulette now, I suppose. But level0 formatted tags & a URL is much faster to get working.
