Extending UML to model Web 2.0-based context-aware applications

摘要

Web 2.0 Mashups offer entirely new opportunities for context-aware application (CAA) developers by integrating Web 2.0 technologies to facilitate interoperability among heterogeneous context-aware systems. From a software engineering perspective, a visualized approach for Web 2.0-based CAA modeling is crucial. Current CAA development, however, cannot provide a conceptual model for Web 2.0-based CAA. Therefore, the development efficiency and potential for reuse are decreased. The UML is a general purpose modeling language with potential for use in many application domains. However, UML often lacks elements needed to model concepts in specific domains, such as Web 2.0-based CAA modeling. To address the above issues, this study presents the Web 2.0-based CAA UML profile, a UML profile for modeling Web 2.0-based CAA.
