Fun with File Formats
In addition to this resource and UK's equivalent (PRONOM/DROID, also mentioned in the linked post), I've found ArchiveTeam's wiki to be very useful for obscure file format details: <a href="http://fileformats.archiveteam.org/" rel="nofollow">http://fileformats.archiveteam.org/</a><p>The `shared-mime-info` database from freedesktop-dot-org is probably more worthy of contribution than these government-backed databases, at least in terms of number-of-end-users. New type definitions in their database will improve the entire Linux/BSD ecosystem (both desktop and server!) because it's consumed not only by fd.o's own `update-mime-database` utility but by many language-specific type-identification libraries too <a href="https://gitlab.freedesktop.org/xdg/shared-mime-info/-/blob/master/data/freedesktop.org.xml.in" rel="nofollow">https://gitlab.freedesktop.org/xdg/shared-mime-info/-/blob/m...</a><p>…including (shameless plug) the new Ractor-based Ruby type library I've been working on in the wake of the `mimemagic` drama earlier this year: <a href="https://github.com/okeeblow/DistorteD/tree/NEW%E2%80%85SENSATION/CHECKING%20YOU%20OUT" rel="nofollow">https://github.com/okeeblow/DistorteD/tree/NEW%E2%80%85SENSA...</a>
