H2020 ACCEPT project: D2.4 -ACCEPT system architecture description v2

This report presents the work carried out in Task 2.3 of ACCEPT regarding the system architecture design process and results up to the date of submission of the second version of the deliverable. In particular, the deliverable includes the high-level architecture model of the complete system, with the initial point being the design as presented in the Description of Work, and further refined and updated based on the work carried out in this period. This high-level architecture has also been mapped to the various SGAM layers to assist the future integration and development activities. The main bulk of the document concentrates on detailing the specifications and characteristics of the various system's software components. A dedicated template was created and circulated to all relevant partners in order to provide the components' functional and non-functional specifications, highlight interdependencies with other components, and declare the input/output data requirements (Annex I – Component’s Specifications and Requirements Template). Additionally, detailed component diagrams were created, and finally, the connection with Deliverable 2.1 (D2.1) was performed via a mapping of components to Use Cases that required relevant functionalities. Sequence diagrams were already created for D2.1 and are not presented here. A new section was created for the second version of the deliverable; it includes an update of the Use Cases, as described in D2.1, following necessary refinements and modifications that occurred in the course of the project. Similarly, the SGAM mapping, the component description and diagrams were updated to reflect the advances of the project. This is the second and final version of ACCEPT's system architecture. It will drive the development of the second and final iteration of the system and its constituent components. Following that, further refinements, if necessary, will be integrated in the new versions of the different components of the projec
