Ask HN: Options for self-hosted media cataloguing tools?

I currently track my media through a variety of sites (e.g., Goodreads for books, Letterboxd for films). I want to:

a) move from these services to something self-hosted; and

b) combine all the various types of media into a single catalogue.

The only two self-hosted tools for this that I've found so far are Bookwyrm and Koillection. Bookwyrm has interesting social features through ActivityPub, but as far as I can tell it isn't extensible to media other than books. Koillection is content-agnostic, but doesn't come with any default media types (inconvenient) doesn't appear to have any sort of import function for the data I export from the sites I'm currently using (dealbreaker).

The key features I would like are:

• visually customisable;

• record notes for each item catalogued;

• automatically retrieves cover art; and

• provides CSV importing.

Can anyone suggest anything that would fulfil these? As far as I can tell, unless someone can suggest something I've overlooked my options are:

• whip up something basic myself (but I'm time-limited at the moment so would like to avoid this if possible);

• use Bookwrym and modify it to extend the Book object; or

• use Koillection and try to manually import my data directly into the database.
