OpenStreetMap Tagging Schema
Validates and queries OpenStreetMap tagging schemas to ensure your OSM data follows proper tagging conventions. Helps discover correct tag combinations and identifies tagging errors or improvements.
What it does
- Validate OSM tag collections against official schema
- Search for proper tag presets by feature type
- Compare tag sets to identify differences
- Suggest improvements for existing tag combinations
- Convert between JSON and flat tag formats
- Retrieve valid values for specific tag keys

Compare two sets of OpenStreetMap tags to identify differences, additions, deletions, and modifications. Performs detailed tag-level comparison showing which tags were added, removed, or changed between two versions. Provides human-readable names for all tags and values using the OSM tagging schema. Use this for reviewing tag changes, understanding feature modifications, analyzing tag history, or validating tag transformations. Returns structured diff with localized names for better readability.
Convert OpenStreetMap tags from flat text format (key=value per line) to JSON object format. This is an INPUT CONVERTER for AI workflows - use it FIRST when you receive tags in flat text format and need to work with them as a JSON object. Handles various text formats including key=value pairs (one per line), whitespace variations, empty lines, and comments (lines starting with #). Returns a clean JSON object with all parsed tags. Essential for processing OSM data from text exports, iD editor output, or JOSM exports.
Get complete detailed information about a specific OpenStreetMap preset. Presets are feature templates that define standard tagging patterns (e.g., the 'Restaurant' preset defines amenity=restaurant and lists fields like cuisine, outdoor_seating, etc.). Returns comprehensive preset information including: display name, all required and suggested tags, supported geometry types, complete list of fields (with template expansion), field types and options, and parent/child preset relationships. Use this to understand exactly how to tag a specific feature type, learn what fields are available for a preset, or get example values for proper tagging.
Retrieve all possible values for a specific OpenStreetMap tag key, with localized human-readable names for both the key and each value. This tool searches through the OSM tagging schema (both predefined field options and preset definitions) to find every documented value that can be used with the specified key. Returns four pieces of information: the normalized key name, localized key display name, a simple array of all values, and a detailed array with localized names for each value. Use this to discover what values are available for a tag (e.g., all amenity types), learn the proper terminology for values, or build UI selection lists. Essential for understanding OSM's controlled vocabularies.
Convert OpenStreetMap tags from JSON object format to flat text format (key=value per line). This is an OUTPUT CONVERTER for AI workflows - use it LAST when you need to present tags in a human-readable text format or export them for use in other tools. Produces clean, consistent key=value format with one tag per line, sorted alphabetically by key. Use this for generating human-readable tag lists, exporting to OSM editors, or sharing tag collections. The output format is compatible with JOSM, iD editor imports, and other OSM tools that accept flat text tag format.
