Grid-based Semantic Integration and dissemination of medical information

Healthcare data and medical information need to be seamlessly accessible and available at all times to the various healthcare stakeholders. Inability to share, integrate and access critical healthcare information is a challenge for the healthcare IT. Moreover, semantic interoperability of health-related heterogeneous data sources is a challenging issue and healthGrids are expected to address this challenge in a systematic manner. This paper proposes a new architecture: ASIDS (architecture for semantic integration of data sources), that could be a potential candidate for solving the challenge of semantic interoperability of geographically distributed heterogeneous data sources. ASIDS has three main components that are loosely coupled (through interfaces) in a distributed manner. This architecture sets the basis for future research in terms of implementing a healthGrid application in real environments.
