This paper presents first steps towards implementing a data layer to support a semi-automated preservation management system for research data in the arts and humanities. We suggest to use e-Science technology and grid middleware to implement a virtualised storage system for research data. We will outline how iRODS (Rule-Oriented Data management System) can be used within an architecture to implement complex, automated, scalable digital preservation strategies.
This paper presents the application profile for machine-actionable data management plans that allows information from traditional data management plans to be expressed in a machine-actionable way. We describe the methodology and research conducted to define the application profile. We also discuss design decisions made during its development and present systems which have adopted it. The application profile was developed in an open and consensus-driven manner within the DMP Common Standards Working Group of the Research Data Alliance and is its official recommendation.
Abstract. The iRODS system, created by the San Diego Supercomputing Centre, is a rule oriented data management system that allows the user to create sets of rules to define how the data is to be managed. Each rule corresponds to a particular action or operation (such as checksumming a file) and the system is flexible enough to allow the user to create new rules for new types of operations. The iRODS system can interface to any storage system (provided an iRODS driver is built for that system) and relies on its' metadata catalogue to provide a virtual file-system that can handle files of any size and type.However, some storage systems (such as tape systems) do not handle small files efficiently and prefer small files to be packaged up (or "bundled") into larger units. We have developed a system that can bundle small data files of any type into larger units -mounted collections. The system can create collection families and contains its' own extensible metadata, including metadata on which family the collection belongs to. The mounted collection system can work standalone and is being incorporated into the iRODS system to enhance the systems flexibility to handle small files.In this paper we describe the motivation for creating a mounted collection system, its' architecture and how it has been incorporated into the iRODS system. We describe different technologies used to create the mounted collection system and provide some performance numbers.
