EPUB 3 Fixed Layout Metadata Finalized
On March 13, 2012 the IDPF Board of Directors unanimously approved elevation of EPUB 3 Fixed Layout Documents to be an IDPF Informational Document. This specification, produced by the EPUB 3 Working Group, defines a set of metadata properties to allow declarative expression of intended rendering behaviors of fixed-layout documents in the context of EPUB 3. It also defines mechanisms to express the intended rendering dimensions.
No new syntactical constructs were defined, only a set of metadata properties and meta tags as per existing extensible mechanisms in EPUB 3 and dependent specifications. This specification is now complete and recommended for immediate implementation by EPUB 3 Reading Systems. Three samples of EPUB 3 publications conformant with Fixed Layout Documents are available via the EPUB 3 Samples open source project, and more samples will be made available imminently (subscribe to the download feed to be auto-notified).
Announcements will be forthcoming soon via the EPUB 3 Working Group mailing list about Ad Hoc Group work to draft a working group charter to pursue development of rendition selection and mapping mechanisms as a next phase of work in this area.
