## What it is
A comprehensive JSON database of MIME/media types aggregated from IANA, Apache, and nginx sources. It contains no logic, just a single public JSON file mapping MIME types to extensions, charsets, and compressibility info.

## Use cases
- look up file extensions for a mime type
- determine the default charset for a content type
- check whether a mime type is compressible with gzip
- build a file upload type validator
- map file extensions to content types in an http server

## When to avoid
- you want a library that resolves MIME types from file paths with an API - use mime-types or mime instead
- you need custom or non-standard media type mappings not in IANA/Apache/nginx

## Facets
- artifact type: dataset
- maturity: stable
- function: serialization, developer-tools
- domain: web-development, files, apis
- platform: browser
