Metadata

EPUB metadata elements that are generated by stylesheets

Cop-e-boox can produce metadata for the Dublin Core metadata schema, from information that you enter inside XML tags using specific elements and attributes. These metadata are generated for EPUB 3.0 ebooks (in the package.opf file) and HTML5 web pages (in the <head> element).

Metadata is information about the book that can be used for marketing and distribution purposes by book publishers. Some metadata elements are mandatory to ensure that ebooks meet basic international standards to help identify ebooks available through the internet. For ebooks that are made available on the internet, metadata information contained in ebook web pages can be searched by internet search websites. This allows ebooks to be found by users looking for particular search terms, which makes metadata important for internet search engine optimisation (SEO).

XML markup to edit

You can enter various metadata information in XML elements and attributes so that when EPUB ebooks and web pages are produced, search terms can be found inside the relevant XML or HTML coding of the ebook.

The following table lists the Dublin Core metadata elements and the XML tagging that generates those metadata elements in output XML and HTML files.
