Thanks.
I needed more flexible metadata support for my OPDS catalog app [1]. To implement this I subclassed the files app, added a JSON-formatted metadata column to the app-specific table and called it a day. The advantage of this approach is that it is easy and flexible - any type of data that can be expressed in JSON can be added as metadata to any file. The disadvantage is that there is only rudimentary support to query JSON-formatted data. Depending on what you need the metadata for this approach might be sufficient, especially if said metadata is usually used as a coherent set (in my case: publication-related metadata, the stuff you'd find on a library card).
