[hugovk]

Based on the last list here:

❯ uv run --python python3.14 --with content-types https://raw.githubusercontent.com/mikeckennedy/content-types/refs/heads/main/samples/compare_to_builtin.py
Compare types in mimetypes vs content-types.

mimetypes: .obj application/octet-stream, content-types: .obj model/obj

I used the MIME types from the following sources.

From https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/MIME_types/Common_types

• application/x-httpd-php

From Wikipedia:

• application/vnd.android.package-archive (added to non-strict list because not in IANA or x- prefix)
• application/x-7z-compressed
• video/x-m4v

From https://mimetype.io

• application/x-debian-package
• application/x-rpm

From https://learn.microsoft.com/en-us/previous-versions/windows/desktop/wmp/file-name-extensions

• video/x-ms-wmv

All the rest from https://www.iana.org/assignments/media-types/media-types.xhtml

---

I didn't add these because they're not in IANA or MDN, and I didn't find any authoritative sources:

.map   -> application/json
.tgz   -> application/gzip
