Interacción orientada a Aspectos en entornos Multiorganizacionales

Unfortunately, current proposals that focus on separation of concerns assume that objects interact by means of object-oriented method calls, which implies that they embed interactions with others into their functional code. This makes them dependent on this interaction model, and makes it difficult to reuse them in a context in which another interaction model is more suited. In this paper, we show that functionality can be described separately from the interaction model used, which helps enhance reusability of functional code and coordination patterns. In order to show that it is feasible, we adapted the multiparty interaction model to the context of Multi-Organisational Web-Based Systems and developed a class framework to build business objects whose performance rates comparably to a handmade implementation; the development time, however, decreases significantly.
