  The previous works on formalizing enterprise application integration (EAI)
scenarios showed an emerging need for setting up formal foundations for
integration patterns, the EAI building blocks, in order to facilitate the
model-driven development and ensure its correctness. So far, the formalization
requirements were focusing on more "conventional" integration scenarios, in
which control-flow, transactional persistent data and time aspects were
considered. However, none of these works took into consideration another
arising EAI trend that covers social and multimedia computing. In this work we
propose a Petri net-based formalism that addresses requirements arising from
the multimedia domain. We also demonstrate realizations of one of the most
frequently used multimedia patterns and discuss which implications our formal
proposal may bring into the area of the multimedia EAI development.
