KER1: Updated AARC Blueprint architecture for emerging technologies and services in pan-European research infrastructures

Updated AARC Blueprint architecture for emerging technologies and services in pan-European research infrastructures

The AARC Blueprint Architecture (BPA) 2025 provides an updated reference architecture for federated Authentication and Authorisation Infrastructures (AAIs) supporting research collaborations. Building on previous AARC Blueprint releases, this update consolidates architectural concepts, components, and interaction patterns reflecting current practice in pan-European research infrastructures.

The Blueprint Architecture describes a common architectural framework and terminology for designing and operating federated AAI solutions, with a focus on interoperability across organisational and technical boundaries. It does not prescribe specific implementations, but instead provides a technology-agnostic reference that can be adapted to different deployment models and environments.

The AARC BPA 2025 is published as part of the AARC TREE project to support alignment, reuse, and a shared understanding of AAI architectures across research infrastructures.

Select one from the following list:

• Other Intangible Results (Justification: Reference Architecture)

Select up to three from the following list:

• Academia/ Universities

• Other Actors who can help us fulfil our market potential

• Research and Technology Organisations

Select up to three from the following list:

• Expanding to more markets /finding new customers (Justification: To promote adoption of the AARC BPA 2025 across Research & Education ecosystems beyond the current AARC community, fostering interoperability alignment, reducing fragmentation, and increasing uptake at European and global scale)

We are looking for additional adopters and implementers of the AARC Blueprint Architecture for international research collaboration. In particular, we welcome feedback from organisations designing or evolving federated AAI architectures and integrating services via AARC-aligned patterns.

We are also interested in collaboration opportunities to validate the applicability of the BPA 2025 guidance in diverse operational contexts, and to collect implementation experience that can inform future revisions and community guidance.

Unique value proposition

The unique selling proposition (USP), also called the unique selling point, or the unique value proposition (UVP) in the business model canvas, is the marketing strategy of informing customers about how one's own brand or product is superior to its competitors (in addition to its other values).

Do you have a scalable business model?

For a business model to be scalable, staffing requirements should grow in a strongly sublinear fashion and/or the revenue per customer (or end-user) should remain relatively stable. Grant-based sustainability is usually not scalable, nor is consulting. Franchising, licensing and platform business models can be.
