AARC Blueprint Architecture (BPA)
The purpose of the AARC Blueprint Architecture (BPA) is to provide set of interoperable architectural building blocks for software architects and technical decision makers, who are designing and implementing access management solutions for international research collaborations.
High-level Objectives
focus on the integration aspects of the blueprint architecture
provide recommendations and guidelines for implementers, service providers and infrastructure operators on implementing scalable and interoperable AAIs across e-infrastructures and scientific communities
work in close collaboration with the policy, pilots, and the training and outreach activities of AARC2
work on the evolution of the blueprint architecture, with a focus on identity provider / service provider (IdP/SP) proxies, scalable authorisation solutions for multi-service provider environments and other solutions for integrating with R&E federations and cross-sector AAIs

| AARC-JRA1.4A | Guidelines on expressing group membership and role information | Information about the groups a user is a member of is commonly used by SPs to authorise user access to protected resources. Apart from the group information that is managed by the user’s home IdP, research communities usually operate their own group managing services. Such services often act as Attribute Authorities, maintaining additional information about the users, including VO membership, group membership within VOs, as well as user roles. It is therefore necessary that all involved SPs and IdPs/AAs can interpret this information in a uniform way. Specifically, the following challenges are addressed by this document:
