This paper proposes a software architecture for dynamical service adaptation.
The services are constituted by reusable software components. The adaptation's
goal is to optimize the service function of their execution context. For a
first step, the context will take into account just the user needs but other
elements will be added. A particular feature in our proposition is the profiles
that are used not only to describe the context's elements but also the
components itself. An Adapter analyzes the compatibility between all these
profiles and detects the points where the profiles are not compatibles. The
same Adapter search and apply the possible adaptation solutions: component
customization, insertion, extraction or replacement
