RI-SCALE_D4.1 – Access Management Systems Specification and Roadmap

This deliverable articulates the architectural design, functional and non-functional requirements, and implementation roadmap for the Access Management Systems within the Data Exploitation Platform (DEP) ecosystem, as part of the RI-SCALE project. It establishes a robust framework to meet the needs of infrastructure providers, DEP end-users, model developers, and operators by ensuring secure, equitable, and environmentally sustainable access to computational resources. The document details two core modules: the Access Management Architecture and the CRedit Management System (CRMS). The Access Management Architecture integrates an Authorisation Framework using Open Digital Rights Language (ODRL) and Open Policy Agent (OPA) for fine-grained, policy-driven access control, an Interoperability Framework supporting federated and decentralised identity management for seamless cross-domain operations, and a Privacy and Consent Management subsystem to ensure compliance with privacy regulations. The CRMS enables scalable resource and credit management by collecting granular metrics on computational resource usage (e.g., CPU, GPU, storage, network transfers) and environmental impacts (e.g., energy consumption, CO₂ emissions), translating these into credit values using transparent, sustainability-focused policies like green-index discounts, and distributing credits equitably via a centralised registry. This deliverable provides a vital blueprint for achieving RI-SCALE’s goals, enabling the DEP to integrate data and computation while addressing the intricate requirements of contemporary research infrastructures.
