@HadrienGardeur:

A number of apps have switched to OPDS 2.0 over the last few years and I would really recommend looking into it (I'd be glad to share examples if you're interested).

Among other things, OPDS 2.0 supports an extended set of metadata and allows for better navigation.

You could enhance publications with the following metadata:

• series info, such as the name of the series and the position of the current book in that series
• more specific contributor roles beyond authors
• include Calibre tags as subjects

OPDS 2.0 allows metadata-level links as well which are very convenient. This way you can include contextual links for series, contributors and tags as well.

Here are a few helpful resources:

• Draft (it's very stable and has been in use for years now)
• JSON Schema
• Example of a publication with series info
• Example of a homepage
