Taginfo collects data about OSM tags from several sources and brings them together for easy browsing and discovery.
Note that taginfo only displays this data. If you want to change it, you have to go back to the source.
List of Sources
Here is a list of currently used sources. More sources might be integrated in the future.
Statistics about keys, tags, and relation types are generated from the OSM database (or an extract) as well as the maps that show the geographic distribution of nodes and ways.
The OSM Wiki is read and all Key:*, Tag:*, and Relation:* pages (in all the different languages) are analyzed. Descriptions, images, related tags, etc. are extracted from them.
Icons and styles are taken from the JOSM editor configuration.
Projects that use OSM tags in some way, such as editors, maps, routers, etc. See the project list.
The taginfo data is updated regularly from the sources.
* All edits until this time will be in the data, later edits might be.
