This document provides an analysis of the requirements the team has collected up to now from scientific communities and project stakeholders. It is an outcome of the "Requirement Analysis" activity in the JRA1 work package, "Architecture for an integrated and interoperable AAI". For the requirement- gathering process, we followed a three-step approach. Section 2 elaborates on the requirement extraction methodology adopted by AARC to ensure that the proposed integrated AAI framework can meet the needs of all stakeholders.
As a first step, we returned to the results of previous activities such as the "TERENA AAA Study" and the FIM4R workshop series and analysed their outcomes in order to produce an initial set of requirements, presented in Section 3.1.
During the second step, this set of requirements was enriched through the results of a survey that was run by AARC during the summer period. The goal of this survey was to identify the barriers communities are currently facing to adopting and using federated access, and to capture their requirements for an interoperable AAI. Α total of 10 scientific communities have responded to this survey and the results are presented in Section 3.2 of the document. In addition, a set of one-to-one discussions were held with key representatives from EGI, ELIXIR, EUDAT and GÉANT, in which we discussed their plans, their successes and the barriers they are facing. The results of these discussions are presented in detail in Section 3.3.
As part of the third and final step, the extracted requirements have been extensively processed, homogenised, merged, filtered, extended and classified to produce a refined set of requirements formulated into tables, shown in Section 4. We have identified 25 distinct requirements, 18 relating to tools and architecture and 7 relevant to policies and best practices. The document's conclusions are drawn in Section 5.
Finally, the questionnaire used for the AARC internal survey is presented in 0, while a brief description of the main AAI use case for each participating user community is provided in Appendix B.
