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... about: about_taginfo: title: About taginfo text: |

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 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. See a list of sources taginfo uses.

about_site: title: About This Site building_on_taginfo: title: Building on taginfo text: |

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

API

Taginfo data can be accessed through a REST API. See the API documentation for the details, some general information is on the OSM wiki. The servers running the taginfo API do not have unlimited resources. Please use the API responsibly. If in doubt contact the maintainers of the site you are using or talk to us on the mailing list.

Download

If you want to play around with the data used by taginfo, you can download the regularly updated Sqlite database files. All the preprocessing is done for you. See the download page for a list of files. Note that some of these files can get quite large. If you want to download them regularly, contact the maintainers of the site you are using or talk to us on the mailing list.

License

The data available through taginfo is licenced under ODbL, the same license as the OpenStreetMap data.

software: title: The taginfo software text: |

The taginfo software was created and is maintained by Jochen Topf. The web design was created by Christian Topf.

Translations

We need translators for the taginfo user interface. See the translations overview for languages that need some work. More information on how to help is on the OSM wiki.

Code

All the software behind the taginfo sites is Open Source. You can get it on GitHub. For an overview see the page about the taginfo architecture on the OSM wiki.

Running your own instance

You can run your own taginfo site, for instance with data for just your own country. Instructions are on the OSM wiki.

Bug reports and feature requests

Bug reports and feature requests should be directed to the GitHub issue tracker. Or you can come talk to us on the mailing list.

Contact/Mailing list

Contact us on the taginfo-dev mailing list if you have questions or want to help.

sources: intro: |

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: title: List of Sources intro: Here is a list of currently used sources. More sources might be integrated in the future. description: db: |

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.

wiki: |

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.

languages: |

Taginfo gets information about the different languages of the world, their codes, names, etc. from several IANA and Unicode registries.

josm: |

Icons and styles are taken from the JOSM editor configuration.

projects: |

Projects that use OSM tags in some way, such as editors, maps, routers, etc. See the project list.

updates: title: Updates intro: The taginfo data is updated regularly from the sources. 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.

Any valid Unicode character can appear in an OSM key but usually only lower case latin letters (a-z) and the underscore (_) are used. Sometimes the colon (:) is added as a separator character.

statistics: tab: Statistics title: Statistics overview fraction: Fraction characters: Characters in key characters_in_keys: plain: Only latin lowercase letters (a to z) and underscore (_), first and last characters are letters. colon: Like A but with one or more colons (:) inside. letters: Like B but with uppercase latin letters or letters from other alphabets. space: Like C but contains at least one whitespace character (space, tab, new line, carriage return, or from other alphabets). problem: Like C but contains possibly problematic characters =+/&<>;'"?%#@\,. rest: Everything else. total: Total whitespace: tab: Whitespace title: Keys with whitespace intro: |

Keys that contain whitespace characters such as space, tab, new 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.

problematic: tab: Problematic title: Keys with possibly problematic characters intro: |

Keys that contain possibly problematic characters: =+/&<>;'"?%#@\, or control 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.

Tag keys can be between 0 and 255 (Unicode) characters long. Very short or very long keys are often, but not always, errors.

This table shows all tag keys for which there are wiki pages available and in what languages they are.

languages: name: Languages intro: |

OpenStreetMap is an international project. Tags and their descriptions can be in any language. This table lists the languages taginfo knows about and how many wiki pages there are in these languages documenting keys and tags, respectively.

This table shows keys for which a wiki page exists but there is not a single instance in the database. 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.

wiki_pages: Wiki pages name_tags: name: Variants of name tags intro: |

This report shows information related to the naming of objects in OSM using the name tag and its variants.

overview: tab: Overview title: Overview bcp47: tab: BCP47 Subtags title: BCP47 Subtags filter: label: Show only subtags of type all: All language: Language script: Script region: Region variant: Variant intro: |

The IETF defines language tags in its standard Tags for Identifying Languages (BCP47). 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.
