Many important practical applications of multimedia are
associated with events or they can be described by events. For
example, reporting an accident, recording the events of a marriage
or a baptism, recording an invited talk, a debate or a lecture,
recording disasters like fires and floods, recording political
or economic events for presentation on TV or for video on
demand consumption, recording an experiment on a lab, recording
the presentation of a product, producing evaluation
reports for products of various types, recording damages of a
building or on disaster areas, or even systematically recording
the components of a complex 3D structure such as a multistore
building may be modeled with multimedia events.
