Interoperability is largely addressed issue from the different stand points of concerned fields. In the IoT for SLE for ageing well field, there is a clear technological approach for interoperability in the IoT technology domain. For instance, interoperability between IoT platforms in the cloud domain, and interoperability across sensors, smart devices and gateways in the edge domain, i.e. the home environment. In the other side, there is a demand of practical solutions for interoperability across applications, services and solutions, set by the Active and Healthy Ageing field perspective. Both points of view of demands converge in the IoT for SLE field, and therefore they must be treated as a whole.

In this session we will analyze the interoperability problems from these two key perspectives and demands and will present one case of integrated solution proposed on ACTIVAGE project. The following topics will be addressed by experts in the respective fields:

• Interoperability needs and solutions across the whole IoT layers
• Interoperability needs across applications, services and solutions in the AHA domain. A vision from the demand side
• Data model for semantic interoperability in the IoT for SLE
• Implementation of an interoperability framework for IoT for SLE
