The document outlines the process of creating and finalizing an EPUB file, detailing its structure and components such as mimetype, meta-inf, and oebps/content. It emphasizes the importance of validation to ensure correctness in markup languages, and provides tools for coding, creating, and quality-checking EPUB files. Additionally, it lists resources for further information and support in EPUB production.
Emerson Epub Coding Day
- 1. Making an EPUB file
- 4. Opening the EPUB • mimetype • META-INF • OEBPS/ Content
- 5. EPUB is a package masquerading as a file format. -Bill Kasdorf, APEX content solutions
- 6. mimetype • Text file • Contents of file: application/ePub+zip • Defines the media type as Open Container Format (OCF)
- 7. META-INF • Contains the container.xml file <?xml version="1.0"?> <container version="1.0" xmlns="urn:oasis:names:tc:opendocument:xmlns:contain er"> <rootfiles> <rootfile full-path=”OEBPS/content.opf" media- type="application/oebps-package+xml"/> </rootfiles> </container>
- 8. META-INF • Optional files: – encryption.xml – signature.xml – rights.xml – manifest.xml – metadata.xml
- 9. 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)
- 11. .ncx file
- 14. 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.
- 15. 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.
- 16. Free Tools • Coding – Notepad++ (PC) – TextWrangler (MAC) – iBooks author (MAC) • Creating/ Zipping – Sigil – Calibre – ePub Zip from MobileRead • Quality Checking – Adobe Digital Editions – EpubCheck – Kindle Direct: Gen & Previewer
- 17. Resources • Twitter: #eprdctn • Liz Castro – EPUB Straight to the Point – Pigs, Gourds, & Wikis • Mobile Reads Forum • IDPF • DefectivebyDesign.org
