This document is the deliverable D3.2.2 or D3.7 "ACTIVAGE Interoperability layer architecture" and represent the main outcome of the activity T3.1 "Specification of the open cross-pilot ACTIVAGE architecture", that is part of Work Package WP3 "ACTIVATE Secure Interoperability Layer". The present document is also tightly related to other WP3 task: T3.4 "Implementation of the interoperability layer" that integrates T3.2 "ACTIVAGE solution for security and privacy" and T3.3 "Building bridges to the IoT protocols and platforms". The overall scope of this deliverable is to present the ACTIVATE Interoperability layer architecture. The content of this deliverable can be summarized as follows: Section 1 describes the nature and the reason why this deliverable 3.2.2 has particular relevance for the ACTIVAGE project. Moreover, this section also set the objectives to the defined structure and organisation of the document, and notes the differences between the 2 versions of the deliverable (D3.2 and D3.2.2). Section 2 is an introductory section that provides a brief description about main concepts from the Internet of Things that are involved in the ACTIVAGE project. This section also addresses the potential of Internet of Things in the context of the Active and Healthy Ageing area that concerns the ACTIVAGE project. In this section, the objectives and proposals of the deliverable are explained in detail besides the challenges that must be confronted to reach the deliverable goals. Section 3 of the present document is dedicated to the IoT Platform Interoperability State of the Art. This section is fruit of an extensive research and organisational collective work, as it is described in the section below. Here the main objectives to pursue, such as the achievement of interoperability within IoT platforms, are explained. The definitions, terminology and main concepts of IoT platforms are detailed in a clear descriptive way and along with a summary of the main features of each IoT platform that is involved in the project this section represent a pivotal part for the semantic interoperability specification in the full project. Interoperability use cases of the Activage IoT Ecosystem Suite (AIoTES) are described. The last point of this section includes the architecture of the Deployment Sites. Section 4 in this deliverable addresses the Semantic Interoperability concept, and the AIoTES common data model is introduced. Section 5 presents the ACTIVAGE Architecture, on where the IoT Semantic Interoperability Layer is included as a core part of it, and its functionality and internal elements are detailed. All main components of the architecture are described in this section, as architectural building blocks. Also, the interfacing among different blocks is explained. The main objective of this part of the deliverable is shared whose first aiming to efficiently and effectively integrate the platforms and devices of the IoT-AHA Ecosystem and second to provide the guidance for deployment sites on procedures for such integration. Finally, the document ends with the conclusions and the future work.
