The integrated Rule-Oriented Data System (iRODS 3.0) organizes distributed data into sharable collections, while enforcing management policies. Each policy controls the execution of a procedure that processes the data at a remote storage location. Standard functions (called micro-services) are chained together into a workflow to compose these procedures. This book is a micro-service workbook, with descriptions of the input and output parameters and usage examples for each of the available micro-services. Together with the iRODS Primer, a community may use this book to assemble a data management infrastructure that reliably enforces their management and administrative policies and procedures.
