Capabilities & Limitations of Calibre-Web Metadata

[holta]

Calibre-Web supports key/value pairs "Identifiers" and "Tags". Both are visible in the standard "Edit Metadata" web interface (screenshot below) for any book or video. To enable real-world uses, let's answer the questions below, to make evolving capabilities + limitations (of Calibre-Web metadata) much more precise:

• [ ] What are the exact string-or-type and character set limitations of Calibre-Web Identifier Type and Identifier Value, and also Calibre-Web Tags?
  • [ ] ASCII? UTF-8? Something else?
  • [ ] What ticket best explains permissible metadata fields? Is there any better than PR janeczku/calibre-web#1877 ?
  • [ ] Where will the reality/limitations of Identifiers (key/value pairs) + Tags be made CLEAR + CONCISE within github.com/janeczku/calibre-web/wiki ? ✅
  • [ ] Concrete Examples, above & beyond a Specification like: https://wiki.openzim.org/wiki/Metadata ✅
  • [ ] If programmatic access to some/all Calibre-Web metadata is not yet cleanly explainable (i.e. EXAMPLES!) then provide hints (OUTLINE) on How That Might Happen In Future!
• [ ] How would Calibre-Web work with SRT subtitles (SubRip Subtitle files) ?
  • [ ] What workflows (whether or not using SRT files) would most empower everyday educators?

Above questions are based on the assumption Calibre-Web metadata can or should be leveraged to accommodate key/value pairs metadata input/integration for enhancement or customization purpose. I am inquiring about the opposite. What if we want to export existing metadata for external use? Should a tool be used to parse the data on book pages or should an additional route be created to output key/values pairs?

key/value pairs metadata input/integration for enhancement or customization purpose

1. Or for very basic search / categorization / archiving — just for starters — we need to know (and document!) current technical limits of Calibre-Web's key/value pairs & tags.

2. Programmatically scraping metadata from (or to) other sources is probably a secondary question for later!?
