 The integrated Rule-Oriented Data System (iRODS) is an open source data management software used by research organizations and government agencies worldwide. iRODS is released as a production-level distribution aimed at deployment in mission critical environments. It virtualizes data storage resources, so users can take control of their data, regardless of where and on what device the data is stored. As data volumes grow and data services become more complex, iRODS is serving an increasingly important role in data management, see [https://irods.org/][c].
