Position paper: Applying model-driven engineering for linking web service and context models

Abstract

Context-awareness is gaining wide importance, especially when targeting pervasive environments, whereas Web Services are often exploited as building blocks of context-aware applications because of their interoperability properties. In this framework, Web Services can be used as business services requiring context data for their functionality, but also as context sources offering access to context information. Combining the development of context-aware Web Services with Model-Driven Engineering techniques requires the identification and matching of appropriate context models with Web Service models. In this paper, a new ongoing research direction is presented, which refers to model transformation for allowing the identification of appropriate context sources and ensuring their compatibility with Web Services. Matchmaking principles between Web Service and context models are examined in order to extract a reasoning mechanism on context adaptation compatibility. In specific, the principles of graph transformation are mainly exploited. © 2011 ACM.
