How the epub standards work together

leave a comment »

The International Digital Publishing Forum (IDPF) maintains the standards describing how ebooks with the .epub extension are constructed. There are three main specifications:

  • Open Publication Structure (OPS)
  • Open Packaging Format (OPF)
  • Open Container Format (OCF)

If you want to know more about these specifications and how they work together, read the recent article How the standards work together from the series provided by Inside Epub. The analogy is drawn between the structure of  a printed book and the aspects that each standard addresses:

  • OPS <==> the vocabulary used to write the book
  • OPF <==> the parts, chapters, and sections of the book
  • OCF <==> the cover and binding of the book

The articles in this series explore epub by looking inside The Curious Case of Benjamin Button, a free ebook available from epubBooks. Screenshots are used to illustrate how the standards have been used in this relatively simple example.

Try this at home – you might find it useful.
