This is the directory of OpenStreetMap tagging data used by the iD editor. It includes presets, fields, deprecations, and more.

• Read up about how you can contribute to the iD Tagging Schema on the contributing page.
• Translate!.
• See the open issues in the issue tracker if you're looking for something to do.

OpenStreetMap itself does not have a formal rigid database schema, but relies on a tagging folksonomy instead.

Editing tools need to know how tags are used in order to facilitate mapping. This Tagging Schema fills that need, but with a number of caveats:

• This isn't authoritative or definitive
• Tagging interpretations may vary from mapper to mapper, place to place, and over time
• Our primary aim is to serve the needs of iD mappers (but other tools are welcome to use this too)
• We support tags based on practicality, usage, and community approval
• Sometimes there are reasons we can't support a tag even if it's used or approved

The westnordost/osmfeatures project, a component of StreetComplete, makes it easier to use this data with Android or other Java platforms.

iD tagging schema is used not only by iD. Here's a list of projects which use the data from the id-tagging-schema.

• The OpenStreetMap wiki documents the current usage of tags, and hosts discussions about proposed new tags.
• iD also incorporates preset data from the name-suggestion-index.
• Other editors also include their own models of interpretations of OSM tags. See for example Vespucci's or JOSM's tagging presets.

See the dedicated CONTRIBUTING page for information about this.
