Apologies for the naive question, but how are the native filesystems for metadata storage, like say if you wanted to store Author for a video, or Location for a photo? Do they have preset available fields, or can they store an arbitrary number of key-value pairs?

Well, there are several tag formats, ie Id3v1, Id3v2, Vorbis comments, APE tags, which have have most needed metadata keys already part of the spec and many can add custom pairs.

Thanks! Just had a look, aren’t those all reliant on the file type? There’s no standardized metadata scheme built into filesystems?
