Making an EPUB file
Professional Workflow
Personal Workflow
Opening the EPUB
• mimetype
• META-INF
• OEBPS/ Content
EPUB is a package masquerading as
a file format.
-Bill Kasdorf, APEX content solutions
mimetype• Text file
• Contents of file:application/ePub+zip
• Defines the media type as Open Container Format (OCF)
META-INF
• Contains the container.xml file<?xml version="1.0"?><container version="1.0"
xmlns="urn:oasis:names:tc:opendocument:xmlns:container">
<rootfiles> <rootfile full-path=”OEBPS/content.opf" media-
type="application/oebps-package+xml"/> </rootfiles></container>
META-INF
• Optional files:–encryption.xml–signature.xml– rights.xml–manifest.xml–metadata.xml
OEBPS/ Content
• Contains all viewable documents (XHTML & .jpg) and stylesheets (CSS)
• Contains the .opf file• Contains the . ncx file (replaced in
EPUB3 with a simplified toc.html file, but only for EPUB3 devices)
.ncx file
Finishing the File
• Once all files are created they and added to the appropriate files, you will need to rezip the files.
• Every file but the mimetype gets zipped (mimetype must be read first).
• You can do this through the command line/ terminal, script, or through an Epub program like Calibre.
• Once zipped, you need to validate.
Validation
• Like all mark-up languages, EPUB needs to be validated.
• It will pick up errors in ncx opf and html files.
• It will alert missing or miscapitalized files.• Use EPUB Check available from Google
code or Safari.
