Abstract
The deliverable provides a first version of the ΕΟ4ΕU technical requirements that will form the basis for the definition of the Platform and EO4EU architecture and detailed design. In keeping with the overall project workflow, the requirements captured and synthesized here will be given to WP3 as input for the first development cycle.
Within the deliverable a description of the architecture to tiers is presented. An analytical representation of components and their class diagram is described. The interaction between the components is presented in sequence diagrams also.
