The Integrated Rule-Oriented Data System (iRODS) is 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 increasingly important in data management. The development infrastructure supports exhaustive testing on supported platforms; plug-in support for microservices, storage resources, drivers, and databases; and extensive documentation, training and support services. This book is a microservice workbook, with descriptions of the input and output parameters and usage examples for each of the available microservices. Together with the iRODS Primer, a community may use this book to assemble a data management infrastructure that reliably enforces their management policies, automates administrative tasks, and validates assessment criteria. The microservices referenced in this book are supported by iRODS version 4.0, an open source release from the iRODS Consortium, http: //irods.org/consortium.

11TH ANNUAL CONFERENCE SUMMARYThe iRODS User Group Meeting of 2019 gathered together iRODS users, Consortium members, and staff to discuss iRODS-enabled applications and discoveries, technologies developed around iRODS, and future development and sustainability of iRODS and the iRODS Consortium.The four-day event was held from June 25th to 28th in Utrecht, Netherlands, hosted by Utrecht University and the iRODS Consortium, with over 130 people attending. Attendees and presenters represented over 60 academic, government, and commercial institutions.

Policy-based data management enables the creation of community-specific collections. Every collection is created for a purpose. The purpose defines the set of properties that will be associated with the collection. The properties are enforced by management policies that control the execution of procedures that are applied whenever data are ingested or accessed. The procedures generate state information that defines the outcome of enforcing the management policy. The state information can be queried to validate assessment criteria and verify that the required collection properties have been conserved. The integrated Rule-Oriented Data System implements the data management framework required to support policy-based data management. Policies are turned into computer actionable Rules. Procedures are composed from a microservice-oriented architecture. The result is a highly extensible and tunable system that can enforce management policies, automate administrative tasks, and periodically validate assessment criteria. iRODS 4.0+ represents a major effort to analyze, harden, and package iRODS for sustainability, modularization, security, and testability. This has led to a fairly significant refactorization of much of the underlying codebase. iRODS has been modularized whereby existing iRODS 3.x functionality has been replaced and provided by small, interoperable plugins. The core is designed to be as immutable as possible and serve as a bus for handling the internal logic of the business of iRODS. Seven major interfaces have been exposed by the core and allow extensibility and separation of functionality into plugins.
