They are primarily closed products with a limited set of features, thus reducing its extension, adoption and reuse. The aim of this paper is to make a first attempt to increase standardization and interoperability oriented efforts by focusing on open systems. We aim to share our experience with developing and deploying Ambient Assisted Living solutions on the top level of the standardized open platform universAAL in real life. This paper identifies the essential aspects of the system architecture and investigates the advantages of providing generic services, shared and reusable components in real life. In addition, this paper presents an evaluation protocol of the different components, focusing on system sustainability and reliability.envirtual showcasesambient assisted living (AAL)standardizationsemanticsinteroperability006conference paper
