AARC TREE Project

The AARC Technical Revision to Enhance Effectiveness, AARC TREE, takes the successful and globally recognised “Authentication and Authorisation for Research Collaboration” (AARC) model and its flagship outcome, the AARC Blueprint Architecture (BPA), as the basis to drive the next phase of integration for research infrastructures: expand federated access management to integrate user-centring technologies, expand access to federated data and services (authorisation), consolidating existing capacities and avoiding fragmentation and unnecessary duplication. 

AARC TREE Methodology

The ‘AARC TREE approach’ to effective research infrastructure access management is driven by an ‘open community involvement’ approach that embeds all work of the project in open forums that are – by design - never specific to the project itself. The gap in ensuring timely implementation of interoperability standards was identified in the initial AARC projects, and was then addressed with AEGIS – established under the AARC methodology of open community forums, and now the standing body for alignment and adoption of the AARC guidelines globally, which outlasted the project. At the basis of the AARC work is a systematic federated access approach to international research collaboration – the best known way to build poly-centric large-scale research infrastructures initiatives.

The approach taken to organise the work ensures that the RIs are central in the delivery model: the RIs drive the requirements, validate AARC TREE outputs in the early stage, drive their consolidation and contribute to the creation of the long term exploitation plan.

The work plan is organised to enable the AARCTREE project to carry out key activities to respond to identified RI needs, to progress iteratively with the feedback received from the stakeholders; this will ensure that the project results deliver value towards the creation of a strategic landscape of the RIs concerning AAI aspects.
