The aim is to establish the overall technical architecture for the project, starting from the identification and collection of requirements from the use cases specified in WP5. WP1 will set the architectural basis of SocEDA, thus providing a common framework for the subsequent design and development to be undertaken in WP2, WP3 and WP4. These work packages will build on the WP1 architecture and refine it towards producing the complete functionalities of SocEDA. They will further provide useful feedback to WP1, thus leading to establishing the final overall reference architecture. Hence, WP1 will serve as an active link between WP2, WP3 and WP4, running for most of the duration of the project.
