Abstract: The workshop will highlight work of the Odum Institute as part of the DataNet Federation Consortiums effort to join the Odum Institutes archive platform with the Integrated Rule-Oriented Data System. Participants will see how archive workflows within the Dataverse platform can be connected to iRODS and leverage the policy based rules enforcement capabilities of iRODS. Participants will be able to create working Dataverse virtual archives that are integrated with the iRODS storage grid technology. The workshop will describe and utilize policies sets that have been selected from the new ISO 16363 audit standards for trustworthy digital repositories. These policies are written into iRODS rules that can be machine enforced. These data management and preservation rules will enforce and monitor a wide range of policies:

  • Number of preservation copies
  • Checksum calculations
  • Frequency of integrity checks
  • Creation of preservation formats
  • Verification of preservation formats
  • Movement of digital objects through a secure firewall
  • Scans for sensitive information to protect human subjects
  • Reporting of preservation status
  • Verification of geographic distributed copies
  • Enforce and report access control

Participants will see machine actionable rules in practice and be introduced to an environment where written policies can be expressed in ways an archive can automate their enforcement.

NDS Labs aims to foster the mission of the NDSC (http://www.nationaldataservice.org) of enabling a National Data Service by bringing together the R&D data cyberinfrastructure efforts currently under way. Towards this NDS Labs allows users to easily deploy containerized versions of these actively developed data technologies and deploy them, elastically, on a number of Cloud resources. Here we show the deployment of the data infrastructure for the Odum effort for the preservation of social science data (http://arc.irss.unc.edu/dvn), specifically the deployment of iRODS (http://irods.org), a federated archive technology being utilized within the DataNet Federation Consortium (http://datafed.org), the deployment of BitCurator (http://www.bitcurator.net) to identify sensitive information within uploaded data (e.g. social security numbers), and the deployment of Dataverse (http://dataverse.org), a data publishing service out of Harvard being linked with the previously deployed iRODS instance to recreate the Odum archive.

Many disciplines in the geosciences utilize complex computational models for advancing understanding and sustainable management of Earth systems. Executing such models and their associated data pre- and post-processing routines can be challenging for a number of reasons including (1) accessing and pre-processing the large volume and variety of data required by the model, (2) post-processing large data collections generated by the model, and (3) orchestrating data processing tools, each with unique software dependencies, into workflows that can be easily reproduced and reused. To address these challenges, the work reported in this paper leverages the Workflow Structured Object (WSO) functionality of the Integrated Rule-Oriented Data System (iRODS) and demonstrates how it can be used to access distributed data, encapsulate hydrologic data processing as workflows, and federate with other community-driven cyberinfrastructure. The scientific contribution is a methodology for creating reproducible scientific workflows where computation routines are co-located with distributed reference data collections. The methodology is demonstrated through an example that leverages both the Terra Populus (TerraPop) and Sustainable Environment-Actionable Data (SEAD) cyberinfrastructure projects for data input, management, and publication. The work is part of a larger effort under the DataNet Federation Consortium (DFC) project that aims to demonstrate data and computational interoperability across cyberinfrastructure developed independently by scientific communities.

Reagan Moore has developed an on-line course on policy-based data management. The material for this course was developed through the DataNet Federation Consortium for three audiences: masters students at the School of Information and Library Science (SILS) at the University of North Carolina at Chapel Hill (UNC-CH); academic partners of the DFC federation hub; and users of the integrated Rule-Oriented Data System (iRODS).  The iRODS middleware is a policy-based data management system that is used internationally for the management of distributed data.

iPres 2015, the 12th International Conference on Digital Preservation, selected “Preservation Policy Toolkit” as best paper. The DataNet Federation Consortium uses a policy-based data management system to apply and enforce preservation requirements. This paper describes the Preservation Policy Toolkit developed by the consortium. In particular, the paper describes the infrastructure needed for preservation, presents examples of computer actionable forms of policies, and provides a generic template for designing actionable preservation policies.

The Daily Tar Heel: Researchers in the School of Information and Library Science have become part of a multi-million dollar effort to create a national data network. Plans for the infrastructure are in their earliest stages, with researchers saying they don’t know exactly how far their research could take them. “The significance of the grant is bigger than the actual monetary award as it position’s Carolina as a leader in data management,” said Karen Green, communications director of the Renaissance Computing Institute, which will be involved in the research.
