Abstract:
This paper reports the work-in-progress on the definition of an object-oriented data model
tailored for multimedia applications within the HERMES project. The wide diffusion of
multimedia applications that use CD quality audio, video, high quality images, etc. and
the initial availability of multimedia databases lead to the need of finding suitable
solutions for the retrieval and the manipulation of multimedia data. In this paper we
present a multimedia data model that addresses the aspects related to data presentation,
manipulation and content-based retrieval. The core of the model consists of three parts:
the Multimedia Description Model, which provides a structural view of raw multimedia data;
the Multimedia Presentation Model, whose main feature is the possibility of describing the
temporal and spatial relationships among different media objects; the Multimedia
Interpretation Model which allows to associate semantic interpretation with the multimedia
objects stored in the database.
