This deliverable summarizes the work that has been done in the scope of Task 2.1 (“State of the art and requirement analysis”). This is the third and last version of a series of deliverables of this task, whose main objective is to specify the pilot scenarios, the involved datasets, and the corresponding user requirements, as well as the system and technical requirements that are being imposed by the platform. As mentioned in the previous version of this deliverable (i.e., D2.2 – State of the art & Requirement Analysis II), the purpose of these series is to track those requirements throughout the project and update them during the progress of the project. As a result, this third and last version depicts the final user and (primary & secondary) data requirements that have been identified after the delivery of the first versions of the scientific reports and provides the final version of the technical requirements of the iHelp platform. As mentioned in the previous versions of this deliverable the approach that has been followed is twofold: A top-down approach that is followed with respect to the user requirements that were collected by the use case providers themselves, after specifying the business goals and objectives of the use case, along with a concrete definition of the scenario. Moreover, a bottom-up approach is additionally complemented that aims to identify and analyse the technical requirements with respect to the technical work packages that are focusing on the platform technological needs. The result of this analysis is an updated list of measurable unambiguous requirements that will drive the design of the overall architecture of the iHelp platform, focusing on serving all different needs of the various use cases of the project. As the project is still progressing, this third and final version of this deliverable will help the architecture designers of the platform and its software developers to adjust the overall architecture and its implementation accordingly, with respect to the principles of the agile methodology. Moreover, as our scope is to continuously keep track with the latest technological advances and how we can take advantage of them while developing our platform, a state-of-the-art analysis regarding the major technologies has been performed that are envisioned to be exploited. This deliverable is being released on M17 of the project and its main aim is to specify the scenarios of the use cases, which drove the user requirements based on their perspective, the final version of the primary and secondary data requirements and the technical requirements as foreseen by the technical partners that are being involved in the design of the overall architecture of the platform.
