MoDAS: Methodology and Tool for Model-Driven Adaptable Services.

Context-aware software for mobile and desktop users is an emerging field for software development. Due to the increasing market, most of the industry and scientific proposals in this field focus on solving context-aware adaptation issues for browser-based applications only. However, other applications, such as web services, also require context adaptation. This paper aims at providing a solution for context-aware web services and their desktop or mobile clients. In this regard, we provide a model-driven methodology for developing adaptable web services: from the initial system model, we will identify where context awareness is required and afterwards the main system skeleton code along with the context adaptation code will be automatically generated. Using this methodology, and also the provided tool, developers will be able to easily create well structured and modularized context-adaptable services, where final service code will be completely separate from context-related functionalities through an aspect-oriented implementation.
