Abstract
When building service-oriented systems the evolution of re- quirements and context is the norm rather than the excep- tion. Therefore, it is important to make sure that the system is able to evolve as well without necessarily starting a com- pletely new development process, and possibly on the y. In this paper we specically focus on the role of the con- text in the adaptation activities. For us context has various dierent facets as it includes information ranging from the situation in which users exploit a service-based application to the conditions under which the component services can be exploited. We elaborate on how and when the context should be dened, exploited, and evolved, and on the im- pact it has on the various activities related to adaptation of service-based applications. We use a case study to exemplify our rst ndings on this subject.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
