Modular Implementation of an Ontology-Driven Multimedia Content Delivery Application for Mobile Networks

Abstract

Today, mobile multimedia applications provide customers with only limited means to define what information they wish to receive. However, customers would prefer to receive content that reflects specific personal interests. In this chapter we present a prototype multimedia application that demonstrates personalised content delivery using the multimedia messaging service (MMS) protocol. The development of the application was based on the multimedia middleware framework METIS, which can be easily tailored to specific application needs. The principle application logic was constructed through three indepdent modules, or “plug-ins” that make use of METIS and its underlying event system: the harverster module, which automatically collects multimedia content from configured RSS feeds, the news module, which builds custom content based on user preferences, and the MMS module, which is reponsible for broadcasting the resulting multimedia messages. Our experience with the implementation demonstrated the rapid and modular development made possible by such a flexible middleware framework.
