Create Taginfo Project File

Generate valid taginfo project files for TILDA topics by analyzing processing code to extract OSM tags.

When to Use

• User wants to create taginfo project files for TILDA topics
• User mentions taginfo, OSM tag documentation, or taginfo project files

Process

1. Identify topic: Read processing/constants/topics.const.ts or ask user which topic to process

1. Read topic file: processing/topics/<topic>/<topic>.lua

- SQL files are ignored - they never introduce new tags - **TodoList files (*_todoList.lua) are ignored** - they are for QA purposes and don't represent the main processing logic - Check for README files that may document OSM tags

1. Extract OSM tags: See references/tag-extraction.md for detailed rules

- Extract only raw OSM tags (before transformations) - Watch for :left, :right, :both variants - extract all used - Infer values from conditional checks and allowed value lists - Exclude tagscc - Tags copied via CopyTags() with tagscc are for data storage only, not filtering/processing logic

1. Create tag entries: For each tag, determine:

- Whether to include value (specific values only) or omit (all values) - object_types from processing functions (see references/tag-extraction.md) - description focusing on TILDA's use case, not general OSM docs

1. Generate JSON: Use assets/example.json as template

- Replace <topic> and <timestamp> placeholders - Timestamp format: yyyymmddThhmmssZ (e.g., 20260123T143022Z)

1. Save file: app/public/taginfo/tilda-<topic>.json (create directory if needed)

Validation

• JSON validates against taginfo schema (see references/taginfo-schema.md)
• Required fields present: data_format, project.*, tags
• Email format valid, URLs valid URIs
• Object types: "node", "way", "relation", "area" only
• No wildcards in values, plain text descriptions
• Only raw OSM tags (no processed/result tags)
