C++ Declarative API – Implementation Overview Within the XRootD Framework / Poenaru, Robert (Bucharest, IFIN-HH) ; Simon, Michal (CERN)
A brief description of the XRootD architecture and its purpose within the Worldwide Large Hadron Collider Computing Grid (WLCG), alongside an overview of the server-and client- sides of the XRootD framework are discussed in the present work. The client-side of XRootD has a relatively new feature called Declarative API. [...]

XRootD Client: A robust technology for LHC Run-3 and beyond / Amadio, Guilherme (CERN) ; Caffy, Cedric (CERN) ; Hanushevsky, Andrew Bohdan (SLAC) ; Simon, Michał Kamil (CERN) ; Smith, David (CERN)
During the LHC era the XRootD framework has proven to be a critical component of numerous data management and software defined storage solutions (most importantly EOS, the CERN storage technology used for the LHC experiments), and as such grew into one of the most strategic storage technologies in the High Energy Physics (HEP) community. Over the last year significant developments in the area of the XRootD client have been introduced, making it even more reliable and robust, as well as easier to debug. [...]

Exploring the virtues of XRootD5: Declarative API / Simon, Michal (CERN) ; Hanushevsky, Andrew (SLAC)
Across the years, being the backbone of numerous data management solutions used within the WLCG collaboration, the XRootD framework and protocol became one of the most important building blocks for storage solutions in the High Energy Physics (HEP) community. The latest big milestone for the project, release 5, introduced multitude of architectural improvements and functional enhancements, including the new client side declarative API, which is the main focus of this study.

PhEDEx Data Service / Egeland, Ricky (Minnesota U.) ; Wildish, Tony (Princeton U.) ; Huang, Chih-Hao (Fermilab)
The PhEDEx Data Service provides access to information from the central PhEDEx database, as well as certificate-authenticated managerial operations such as requesting the transfer or deletion of data. The Data Service is integrated with the SiteDB service for fine-grained access control, providing a safe and secure environment for operations. [...]
