About taginfo



OpenStreetMap uses tags to add meaning to geographic objects. There is no fixed list of those tags. New tags can be invented and used as needed. Everybody can come up with a new tag and add it to new or existing objects. This makes OpenStreetMap enormously flexible, but sometimes also a bit hard to work with.

Whether you are contributing to OSM or using the OSM data, there are always questions like: What tags do people use for feature X? What tags can I use for feature Y so that it appears properly on the map? Is the tag Z described on the wiki actually in use and where?

Taginfo helps you by showing statistics about which tags are actually in the database, how many people use those tags, where they are used and so on. It also gets information about those tags from the wiki and from other places. Taginfo tries to bring together all information about tags to help you understand how they are used and what they mean.

The taginfo software was created and is maintained by Jochen Topf. He also maintains the main taginfo web site. Christian Topf created the web design.

Taginfo integrates data about tags from several sources:

From the OSM database statistics about key and tag usage.

The Wiki contains some documentation for keys and tags.

Icons and styles are taken from the JOSM editor configuration.

The data is updated regularly, see when this was last done.

More information about the sources on the wiki...

Bug reports should be filed in the OSM bug tracker using the 'taginfo' component.

Taginfo developers and site maintainers hang out on the
taginfo mailing list.

Using taginfo in your own projects

How you can contribute

You can use the data behind taginfo in your own projects:

If you want to play around with the data itself, you can download the regularly updated databases used by taginfo. All the preprocessing is done for you. See the download page for more information.

Taginfo data can also be accessed through a REST API. See the API call documentation for the details, some general information is on the wiki. The server running the taginfo API does not have unlimited resources. Please use the API responsibly. If in doubt contact the taginfo maintainers.

The data available through taginfo is available under the same license as OpenStreetMap itself.

All the parts of taginfo are Open Source. Programmers can fork taginfo on Github and play around with it. We welcome help developing taginfo.

We also need translators for the taginfo user interface. The translation files are on Github. More info on how to translate on the wiki.

You can run your own taginfo site, for instance with data for just your own country.

Contact us on the taginfo mailing list if you can offer any help.
