The Working Group Identity and Access Management (IAM) aims to consolidate processes, policies and architectures in order to facilitate the management of digital identities and federated access to resources within and across the NFDI consortia. The working group therefore follows the three main objectives: Conceptional work including the evaluation and creation of blueprints, especially the AARC BPA, to establish an AAI for the "one NFDI" as well as concepts for the integration of existing tools and resources in this infrastructure Connecting NFDI AAI and the NFDI consortia with relevant initiatives on state, national and international levels. Consulting to support communities and resource providers to connect to the “one NFDI AAI”. Over the course of the next two years, the working group will follow milestones to (1) provide short term AAI guidelines that allow service providers within the NFDI to connect their services to existing AAI infrastructures, (2) Build a baseline scheme for an identity space to exchange informational attributes about identities, (3) establish role and group management services and finally (4) provide an IAM architecture for the "one NFDI".
