OpenStreetMap uses tags of the form key=value to add meaning to geographic objects. Taginfo collects information about these tags from several sources to help you understand what they mean and how they are used.
more: More about taginfo... international: see: See other taginfo sites... sources: intro: |Taginfo takes 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.
data_until: Data until last_update_run: Last update run data_until_explanation: All edits until this time will be in the data, later edits might be. to: to download: intro: |Here you can download the databases used by taginfo. All the data is stored in Sqlite databases. The database files are then packed with bzip2.
If you don't want to download these databases, but need automated access to the data, you can also use the API.

line, carriage return, or whitespace characters from other
alphabets.
Whitespace in keys can be confusing, especially at the
beginning or end of the key, because they are invisible. Generally
the underscore (_) should be used instead.
Keys that contain possibly problematic characters: =+/&<>;'"?%#@\,. These characters
can be problematic, because they are used to quote strings in
different programming languages or have special meanings in XML, HTML,
URLs, and other places. The equal sign is used often as separator
between tag keys and values.
Keys that appear in this list are not necessarily wrong though. But
in many cases they are just results of some error.
This table shows keys that appear more than 10 000 times in the OSM database but have no wiki page describing them. If you know anything about one of these keys, please create the wiki page by clicking on the link in the leftmost column and describe the key. Sometimes it might make sense to create a redirect to a different wiki page instead. To do this put just one line with #REDIRECT [[page name]] in the wiki page.

This is not necessarily an error (maybe somebody added the documentation in the wiki as preparation for using a key or the wiki page documents a now obsolete key), but it can also be a typo or other error.

Language tags consist of one or more subtags describing the language, script, variants, etc. The following list shows the subtags currently registered that are relevant for OSM. For more information see also the Wikipedia entry on IETF language tags and the langtag.net site.
Note that the data shown in this table is not from OpenStreetMap, it just shows the building blocks that can be used to describe languages irrespective of whether they are actually used in OSM.
