As you gather from reading this book, the field of multimedia is widely divergent. However, when you develop a multimedia application, you will find that all topics treated so far will become relevant. There will be a need to mix multiple media formats. You will have to find suitable codecs for your video. You will be asked whether search is possible. And, not the least important, you will have to balance navigation and presentation.

This chapter is based on the work we, that is my students, have been doing in the domain of cultural heritage. In the first section, we will introduce the notion of digital dossier and outline our general approach. We will then in section 2 look at some examples, and describe how we deploy concept graphs as a universal navigation tool for complex information spaces. Finally, in section 3, we will explore the options for presenting multimedia material and discuss the design issues as well as the technical issues that have arisen in the course of our work.
