Comparison of the 100th use of a tag in the OSM database and its first documentation in the OSM wiki. Each blue disk represents a tag. The size of the disk reflects how frequently the tag is used in the OSM database. Only tags that are used at least 1,000 times in the data and that are documented in the OSM wiki are included, tags with value ~*~ are excluded.
