/ATLAS Collaboration
The intelligent Data Delivery Service (iDDS) has been developed to cope with the huge increase of computing and storage resource usage in the coming LHC data taking. It has been designed to intelligently orchestrate workflow and data management systems, decoupling data pre-processing, delivery, and primary processing in large scale workflows. [...]

WLCG Token Usage and Discovery
/ Bockelman, Brian (Morgridge Inst. Res., Madison) ; Ceccanti, Andrea (INFN, Italy) ; Dack, Thomas (Daresbury) ; Dykstra, Dave (Fermilab) ; Litmaath, Maarten (CERN) ; Sallé, Mischa (Nikhef, Amsterdam) ; Short, Hannah (CERN)
Since 2017, the Worldwide LHC Computing Grid (WLCG) has been working towards enabling token based authentication and authorisation throughout its entire middleware stack. Following the publication of the WLCG Common JSON Web Token (JWT) Schema v1.0 [1] in 2019, middleware developers have been able to enhance their services to consume and validate the JWT-based [2] OAuth2.0 [3] tokens and process the authorization information they convey.

WLCG Authorisation from X.509 to Tokens
/ Bockelman, Brian (Unlisted, US) ; Ceccanti, Andrea (INFN, Italy) ; Collier, Ian (Daresbury) ; Cornwall, Linda (Daresbury) ; Dack, Thomas (Daresbury) ; Guenther, Jaroslav (CERN) ; Lassnig, Mario (CERN) ; Litmaath, Maarten (CERN) ; Millar, Paul (DESY) ; Sallé, Mischa (Nikhef, Amsterdam) et al.
The WLCG Authorisation Working Group was formed in July 2017 with the objective to understand and meet the needs of a future-looking Authentication and Authorisation Infrastructure (AAI) for WLCG experiments. Much has changed since the early 2000s when X.509 certificates presented the most suitable choice for authorisation within the grid; progress in token based authorisation and identity federation has provided an interesting alternative with notable advantages in usability and compatibility with external (commercial) partners.
