           <p>In 2018, CMS embarked on a process to select a new data management solution. The previous solution was over a decade old, difficult to maintain, and would not easily adapt to the data rates and technologies used for data transfers in the HL-LHC era. As a result of this selection process, CMS decided to adopt Rucio which was, at the time, used by on major experiment and a couple of smaller experiments.</p>
           <p>This choice has been a good one for CMS, allowing them to no longer operate a service at each of more than 50 data sites, to scale easily to new rates of data transfer, and to adopt new technologies for data transfer as needed. CMS aggregate data rates, managed by Rucio, regularly top 40 GB/s and have been proven to reach 100 GB/s.</p>

It is the successor to the Belle experiment operated from 1999 to 2010 and expected to collect around 50 times more data. In order to be able to manage this huge volume of data, Belle II decided to move to Rucio that has demonstrated its capabilities at scales much higher than the current volume managed by Belle II (over hundred million files, more than 25 Petabytes) and that will be able to cope with the volume expected in the future.</p>
+		  <p>Since January 2021, Rucio is responsible for managing all the data produced across the data centers used by Belle II over their full lifecycle. In particular it ensures the proper replication of all the data according to the replication policies of Belle II. Rucio fits very well to Belle II needs and it allowed to simplify and automate many tasks.</p>
+		  <p>At the beginning of 2024, Rucio was also chosen to become the official metadata service of Belle II in the near future after a careful evaluation. We expect to gain immediate benefits from it when this functionality is enabled in production.</p>

DUNE consists of two neutrino detectors situated underground with roughly 1300 km between the near and far detectors. The near detector will be located on site at Fermi National Accelerator Laboratory with the far detector located 4850 ft underground at Sanford Underground Research Facility in Lead, SD. These detectors will be exposed to the neutrinos created by the Long Baseline Neutrino Facility at Fermilab.</p>

           <p>The raw data produced from the DUNE detectors are unique compared with other HEP experiments for both readout of neutrino interactions and observation of astrophysical events. The DUNE far detectors will consist of several large Liquid Argon Time Projection Chambers filled with approximately 17 kilotons of liquid argon. The far detector data produced from a single trigger of DAQ can vary in size from 100 MB for neutrino interaction candidates to larger than 100 TB for supernova burst candidates. The cataloging and replication of the large data volumes poses an interesting challenge for DUNE when trying to optimize workflows with large I/O requirements based upon these large volume trigger records. From the beginning, DUNE chose Rucio to manage data distribution, replication, and removal. As well, DUNE has become an active part of the Rucio development community as the experiment brings unique needs to data management.</p>
