EPUB in het kort
EPUB
EPUB grew out of the digital publishing standards ecosystem and later moved under W3C stewardship, reinforcing its identity as an open publishing format rather than a vendor-specific storefront file.
NCX in het kort
NCX
NCX was defined in the 2005 DAISY and ANSI-NISO talking-book standard, then carried forward into EPUB 2 and later treated as a legacy compatibility feature once EPUB 3 introduced XHTML navigation documents.
