IAM4NFDI explained in text

IAM4NFDI provides researchers with seamless access to digital research resources! By connecting and expanding Identity and Access Management (IAM) systems, this initiative enables researchers across Germany and worldwide to seamlessly access tools, data, and services within the National Research Data Infrastructure (NFDI). The decentralised, federated approach ensures secure and easy integration with external platforms like the European Open Science Cloud (EOSC), benefiting thousands of institutions and researchers.

Agile adoption to IAM4NFDI via Incubators

An incubator speeds up the development and integration of the service in the community in an agile work programme.

Benefit: Incubators aim to develop, foster, and mature (new) ideas in identity and access management.
Example: Connect your service to the CAAI or Infrastructure Proxy.

What to expect: One incubator lasts for 1 cycle = 6 months. 1 sprint per month. Sprint demo every month.
Call: Call for submissions is published 2 months before each cycle begins.
Application: NFDI Consortia, NFDI services, or external partners can apply using a provided template.

how to apply

Project development phases and current status in the Base4NFDI process

01.02.2026 - 31.01.2028 (ongoing!)

The IAM4NFDI project is advancing into its Ramp-Up phase to transition the established NFDI Authentication and Authorisation Infrastructure (NFDI-AAI) consisting of the Community AAI services, the Infrastructure Proxy, and its Policy Framework into an operational, reliable, and sustainable Basic Service. Building upon the successful integration of most NFDI-Consortia, this phase focuses on scaling the service, enhancing the user experience, and supporting the integration of more complex services through incubator projects. IAM4NFDI will continue to proactively integrate the evolving standards and technologies, especially those relevant for the EOSC AAI, to meet future needs of the NFDI in its role as the German national node. To ensure long-term viability, we are establishing a durable operational model with the service providers and want to shape and integrate into the future sustainable governance and funding strategies in close cooperation with the NFDI association and Base4NFDI.

01.02.2024 - 31.01.2026

This stage focused on integrating various services into the NFDI-AAI, with different levels of integration complexity addressed by separate work packages. NFDI consortia can integrate some services themselves using provided documentation, while more technically involved integrations will be handled in specific work packages. An incubator, modelled after the GEANT project's concept, will facilitate community-driven development for integrating specific services and extensions, with the involvement of IAM4NFDI and NFDI Consortia representatives.

01.03.2023 - 31.01.2024

Even before the project began, the team developed a modular architecture for the future NFDI Authentication and Authorisation Infrastructure (NFDI-AAI) based on concepts that are already established in the international research communities (AARC). The same applies to the underlying standards and best practices such as attribute profiles and the policy framework. The concept of a Community AAI plays a central role here, for which as-a-service solutions will be developed. During the initialisation phase, these concepts will be implemented and evaluated together with the NFDI community. The experience gained here will be an important basis for the integration phase.

How does Base4NFDI support the service development?

Service Stewards play a crucial role in supporting the development and integration of basic services within NFDI. They facilitate collaboration between consortia, partner organisations, and sections, acting as requirement engineers and consolidating information for Base4NFDI, leveraging their domain-specific knowledge.
