Engineering Hypermedia for Multi-channel Access, with the use of XML

The plethora of networked devices and platforms that continuously come to light, as well as the emergence of alternative ways to access the internet, have increased the demand for multichannel access to hypermedia applications. Researchers and practitioners nowadays not only have to deal with the challenges that classic hypermedia applications pose, but also have to face numerous considerations with respect to multi-channel delivery of the applications. This paper presents an attempt for attacking the problem of multi-channel hypermedia application development. In specific it proposes a model that explicitly separates the hypermedia content from its presentation to the user through a document engineering perspective, by employing XML content storage and XSL transformations. Our work is based upon the empirical results of designing, developing and deploying hypermedia applications on multiple platforms and client devices, and on the practices of wellestablished hypermedia engineering techniques.
