Working with EPUB

EPUB is a free and open electronic book standard by the International Digital Publishing Forum (IDPF). It was designed for reflowable content, meaning that the text display can be optimized for the particular display device used by the reader of the EPUB-formatted book.

Oxygen XML Developer plugin opens EPUB files in the Archive Browser view, exposing all their internal bits and pieces:

Here you can edit, delete and add files that compose the EPUB structure. To check that the EPUB file you are currently working is valid, invoke the Validate and Check for Completeness action. To perform the operation, Oxygen XML Developer plugin uses the open-source EpubCheck validator which detects many types of errors, including OCF container structure, OPF and OPS mark-up, as well as internal reference consistency. All errors found during validation are displayed in a separate tab in the Errors view.

Note: Invoke the Open in System Application action to see how the EPUB is rendered in your system default EPUB reader application.
