In this paper conceptions and architectural considerations of the OSAMI project and their specializations towards the requirements of the e-health domain by the German subproject (OSAMI-D) are described. Along with the expected shift of healthcare service between stationary towards ambulatory care, a standardized way of integrating medical data acquired at home into the IT infrastructure of hospitals and the synchronization with medical workflows have to be implemented. Therefore, the OSAMI-D project will provide open source components that implement the required interfaces. Preliminary results of the requirements analysis and the implementation of first domain-specific services are presented. These services are used to realize two home care scenarios, which support ambulant cardiologic rehabilitation (indoor and outdoor). Special emphasis is placed on standards and formats for the communication and storage of patient data.
Abstract-Bringing heterogeneous devices like industrial machines, home appliances, and wireless sensors into the Web assumes the usage of well-defined standards and protocols. Our approach combines the Web Service standard for devices DPWS with the embedded system and component management standard OSGi. It implements the specifications of OSGi Remote Services, as well as OASIS Discovery, Eventing, SOAPover-UDP, and DPWS. Furthermore, runtime WSDL generation and interpretation is supported, as well as the presentation URL feature which automatically provides a web browser user interface for interactive device access. Thus, our approach is an appropriate and comprehensive basis for the seamless, flexible, and standard-compliant integration of things into the Web.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
