Feature proposal: more metadatas set and export button
More metadatas may be useful in severals contexts. As per exemple for accessibility features as described in http://kb.daisy.org/publishing/docs/metadata/schema-org.html For discoverability we also need export of metadatas in the most commons formats such as Onix and Mark.
- in the metadatas dialog box, propose at least schema.org accessibility metadatas but also some essentials for book production, such as Abstract, Source (if any). Maybe free lines to add specific metadatas (responsibility of the user to insure it’s a correct set)
- in the metadatas dialog box or in the book builder, add a button “export metadatas” and propose a conversion format (.csv, onix and mark).
- in the books page, add a button “export collection metadatas) and propose a conversion format (.csv, onix and mark).
