Facing this problem, we propose to ensure adaptation safety by abstracting away properties. We define a metamodel for adaptable components on which we describe safety properties independently from component platforms.

However, reusing the user interfaces that come with software systems is still an ongoing work. The Alias framework helps developers to reuse and compose user interfaces according to the way they are composing new systems from smaller units as a mean of speeding up the design process. In this paper we describe how we rely on Model Driven Engineering to operationalize our composition process.

In this context, mobile applications must cope with service continuity during network disconnections. On the other hand, component platforms provide mechanisms to adapt applications by modifying component assemblies and to control these adaptations dynamically. However, these platforms are dedicated to traditional environments and do not take into account assembly breaks resulting from disconnections. In this paper, we propose to handle disconnections as assembly adaptations in order to determine whether work around components are useful. We extend the Satin model, created to control component assembly adaptations, so as to control nomad component disconnections.

When performed at runtime, such adaptations may lead application execution to unsafe states. It arises in component and service-oriented platforms as well as aspectoriented frameworks that support run-time adaptation. However such platforms hardly manage adaptation-related errors. In this paper we propose a generic safety service that can be used with different platforms as the need to determine safety of run-time adaptation is independent of the underlying technology.

Composition is a challenge for Human Computer Interaction and Software Engineering communities. These communities have proposed metamodeling approaches in order to address composition at a high level and to overcome technological diversity as advocated by the Model Driven paradigm. However, such metamodels cover only one aspect of system composition. This leads to build incomplete systems. To tackle this problem, we propose a global composition approach that takes into account the functional composition choices and that maintains the interaction links between interactive and functional parts of systems. This paper presents the metamodeling on which relies the proposed composition approach.

The aim is to detect and manage conflicts that may arise when composing UI driven by business needs. The originality of this composition engine is to reason at an Abstract level which simplifies the composition algorithm and makes it reusable and oblivious to technology. The composition engine is the core of the Alias framework that reduces the re-engineering efforts needed to obtain the UI of an application built by composition of smaller ones following the "programming in the large" paradigm.

Each application can be described by a pair of a visible part -the User Interface (UI) -and a hidden part -the tasks and the Functional Core (FC). Few works address the problem of application composition by handling both visible and hidden parts at the same time. Our proposition described in this paper is to start from the visible parts of applications, their UIs, to build a new application while using information coming from UIs as well as from tasks. We base upon the semantic description of UIs to help the developer merge parts of former applications. We argue that this approach driven by the composition of UIs helps the user during the composition process and ensures the preservation of a usable UI for the resulting application.
