The new version of the standard format for electronic publications
Increased possibilities with EPUB3
Through innovative publications, the specification 3 version of EPub is beginning to expand, having already been released in November 2011. Since Epub2 has become the standard for providing the complete and correct display of electronic books on readers and software, from specialised APPs to browser plug-ins, the support for interactive and multimedia features on readers has risen. In the EPub3 specification, HTML5 replaces the previous XHTML and offers new multimedia possibilities that are near-revolutionary compared to the previous set of functions, which were only possible with proprietary solutions until then.
Technologies in EPUB3
Container format for metadata, navigation and content
An EPub b file is essentially a ‘packed web page’ with additional information. The EPub format provides meta information and information on the navigation within documents as a container alongside the content of a publication, in order to allow an optimised display and uninterrupted reading flow. Specifications on the desired rendering can also influence the display towards a fixed layout . Metainformation can now be specified more easily in the OPF (Open Packaging Format) file using meta elements. External meta information is also possible (like ONIX data sets). Navigating via NCX files is considered outdated, so using an EPub Navigation Document (END) makes it possible to use a simpler HTML list structure. Types of lists of figures or tables can also be defined this way. HTML5 offers further possibilities for highlighting semantic classification within documents, such as in chapters by using section elements or magazine articles by using article elements.

Available readers and software
Publishers have tremendous opportunities available for publishing and linking multimedia content and text. However, the success of new innovative concepts requires the distribution of suitable reading devices. Here it is to be expected that a market will arise through the capabilities of mobile devices paired with the appropriate software. Likewise, browsers are always coming up with improved functions. At the moment, however, there is no product on the market that supports EPUB3 in an ideal or complete way. It is nevertheless advisable to seize the opportunity to make maximum use of the technical possibilities to make a publication as an e-book more valuable.
