This is the directory of OpenStreetMap tagging data used by the iD editor and others. It includes presets, fields, deprecations, and more, recording various information about OpenStreetMap tagging, in a machine-readable format for easy use by editor software. It does this by abstracting and slightly simplifying OpenStreetMap's Folksonomy as documented on the OpenStreetMap Wiki, the community forum and other sources. The main goal is to allow OSM editing software to display the OSM data in a way that is intuitive and easy to understand for the user (i.e. such that they don't have to read the full documentation in order to use the respective tags). iD tagging schema is following community consensus rather than inventing new tagging methods.

• 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.

• The OpenStreetMap wiki documents the current usage of tags, and hosts discussions about proposed new tags.
• The ideditor/schema-builder project holds the documentation for the data format used in this repository
• 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.
