Wiki is a collaborative authoring platform for collective information to quickly gaining popularity in content publication. However, Wiki lacks of the reusability and interoperability to support a wider range of publication requirements. On the other hand, Linked Data approach, which may be considered as a new wave of Semantic Web, is turning from the conventional HTML-based Web to RDF-based Web, and creating added value from data. Linked Data also makes the World Wide Web into a global database that we call the Web of Linked Data. Clients (human and agent) can query Linked Data from multiple sources at once and combine it on the fly. EPUB specification is the most widely adopted and deployed standard for electronic publishing. A significant challenge of Web content (Both wiki and RDF) rendering is how to automatically convert Web content into the EPUB eBook that can be accepted by EPUB eBook reader. To address Web content rendering issues, this study develops two EPUB Generators, including Wiki-to-EPUB Generator (WEGen) and RDF-to-EPUB Generator (REGen), to automatically generate EPUB eBook from Wiki content and RDF triples. The EPUB Generator contains three main modules: XML Converter, Digital Content Repository and EPUB eBook Composer. To demonstrate the feasibility of WEGen and REGen, two EPUB eBooks are automatically generated from wiki contents and DBpedia endpoint to reveal the reusability and interoperability for EPUB publication.
