Request

Being able to build a kiwix-serve URL with only in-ZIM (thus Metadata) information.

Ideally, I'd like to be able to call /viewer#{bookId} or /content/{bookId} and get to said book. bookId here being the ZIM UUID.

Why would one need this?

• The bookName to a book is based on the filename on disk at time of addition to kiwix-serve. This is thus somewhat volatile.
• The bookName can be extracted from the OPDS catalog (link to /content/), of a running kiwix-serve. Needs live-querying of kiwix-serve.

Assuming I want to link to a specific content from outside of kiwix-serve ; if I can't rely on a running OPDS endpoint (as the libkiwix viewer does), I have to:

• known the filename passed to kiwix-serve
• duplicate and maintain part of libkiwix code to generate the bookName.

Adding support for this seems quite simple.

If the BookName part of URL looks like a UUID, it can be tested first and if it matches, a redirection to the current format happen.

This would ensures continuity of current behavior and allows UUID-based link to be presented as human in URL of browsers.
