Data
Tom's Obvious Minimal Language is a data format commonly identified by .toml. Use the listed signatures, MIME types, and structure notes to validate files beyond the extension.

}Tom's Obvious Minimal Language is used for data exchange, imports, exports, parser testing, and validation workflows. Encoding, delimiters, versions, and container structure often change implementation behavior.
Untrusted input is not safe just because the format was detected. Account for parser exceptions, large files, unexpected encodings, and external references.
11 samples help test leading-byte detection, parser errors, upload limits, and download behavior.

The MIME type for Tom's Obvious Minimal Language is application/toml, text/toml.
Tom's Obvious Minimal Language files use the .toml extension. The extension is a convention only and does not guarantee the file contents, so combine it with signature and structure checks.
