The Rucio File Catalog in DIRAC implemented for Belle II

Abstract

DIRAC and Rucio are two standard pieces of software widely used in the HEP domain. DIRAC provides Workload and Data Management functionalities, among other things, while Rucio is a dedicated, advanced Distributed Data Management system. Many communities that already use DIRAC have expressed their interest in using DIRAC for Workload Management in combination with Rucio for Data Management. In this paper, we describe the integration of the Rucio File Catalog into DIRAC that was initially developed for the Belle II collaboration.
