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.
