m-WOnDA: the Write Once n Deliver Anywhere model for mobile users

Abstract. The design and development of hypermedia applications that are deployed on the Wireless World Wide Web is a daunting task because of the various available platforms and the restrictions and capabilities imposed by the lack of established standards and the exponentially increasing number of emerging platforms. There are now justifiable research and development efforts that attempt to formalize the engineering process of such applications in order to achieve certain quality attributes like modifiability, maintainability and portability. This paper presents such an attempt for designing a conceptual model for hypermedia applications that allows for easy update and alteration of its content as well as its presentation and also allows for deployment in various mobile platforms. In specific this model explicitly separates the hypermedia content from its presentation to the user, by employing XML content storage and XSL transformations. Our work is based upon the empirical results of designing, developing and deploying hypermedia applications for mobile platforms, and on the practices of well-established hypermedia engineering techniques.
