2. What is PURR? Technical and institutional infrastructure

3. The Purdue University Research Repository A brief overview: • The Purdue University Research Repository (PURR) is a research collaboration and data management solution for Purdue researchers and their collaborators. • Data management support • A workspace for researchers to collaborate on research and publish datasets online • Access to published datasets with unique Digital Object Identifier (DOI) • Long-term preservation component • https://purr.purdue.edu

4. The Purdue University Research Repository A customized instance of hubzero ® • PURR utilizes HUBzero as its foundation: https://hubzero.org • Designed to facilitate virtual communities, online collaboration, research, and teaching • Built on open source LAMP (Linux Apache, MySQL, and PHP) platform with Joomla! Content Management System (CMS) • PURR was specially customized for data stewardship which includes a workflow for the curation, publication, dissemination and preservation of datasets • Unique customization of HUB software will be added to base HUBzero package in next release

5. The Purdue University Research Repository Collaborative institutional infrastructure • Collaborative effort • Purdue University Libraries • Information Technology at Purdue (ITaP) • Office of the Vice President for Research (OVPR) • Governed by an Executive Committee, Steering Group, and a Working Group • PURR Libraries team • Project Director 50% • Digital Data Repository Specialist 100% • Two Software Developers 100% • Metadata Specialist 20% • Digital Archivist 25% • Two Graduate Assistants 50% • Graduate Assistant 25%

6. Data Preservation ISO 16363 & OAIS

7. Digital Preservation in PURR The data deluge • Long-term data management plans required by many federal funding agencies • Trustworthy repositories, sound metadata creation and capture, open standards for file formats, and information literacy vital to longevity of digital resources • Working Group drafted PURR Digital Preservation Policy using the Trustworthy Repository Audit Checklist (TRAC) as guiding document. • TRAC/ISO 16363 influenced documentation such as mission statement, policies, job descriptions, business plan, etc.

8. Digital Preservation in PURR Developing policies and strategies • PURR’s preservation mandate and its organizational commitment. • PURR commits to preservation for a period of 10 years after which the content is subject to the Libraries’ selection criteria and archival appraisal • Preservation strategies: full preservation, bit-level preservation and no preservation. • All objects receive bit-level maintenance, a DOI permanent identifier, PREMIS preservation metadata, onsite and offsite backups, regular virus checks, regular rotation to new storage media. • PURR accepts all file formats but recommends formats which are more sustainable long-term.

9. Digital Preservation in PURR OAIS & Distributed digital preservation • The Open Archival Information System (OAIS) Reference Model is a standard in digital preservation and an ISO standard – ISO 14721 • Producers submit content item for publication with appropriate Dublin Core metadata – this acts as the Submission Information Package (SIP) • The Content Information (CI) is then bundled together with Preservation Description Information using Library of Congress specifications for BagIt. This is the Archival Information Package (AIP) • Unlike most OAIS repositories, the Dissemination Information Package (DIP) is not derived from AIP but rather its SIP. • In February 2013, Purdue joined The MetaArchive Cooperative

13. Metadata goals for purr • dataset metadata Capture all pertinent information about the dataset file for long term preservation • Descriptive metadata • Administrative metadata • Technical metadata • Structural metadata • Rights metadata • Preservation metadata

14. Metadata Generation Metadata Standards FOR PURR Metadata Encoding and Transmission Standard (METS) • Wrapper DCMI Metadata Terms (dcterms) • Descriptive metadata Metadata Object Description Schema (MODS) • Dataset ownership • Access condition Preservation Metadata: Implementation Strategies (PREMIS) • Preservation metadata

15. Metadata generation Why mets? METS acts as a structured container into which other standard metadata schemas can be pointed to externally or embedded internally. Structure: • Descriptive Section <mets:dmdSec> • Administrative Section <mets:amdSec> • Technical Section <mets:techMD> • Rights Section <mets:rightsMD> • Digital Provenance Section <mets:digiprovMD> • File Section <mets:fileSec> • File Structure Section <mets:structMap> DCTERMS PREMIS PREMIS & MODS METS

16. Metadata Generation • Why Qualified Dublin core? Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) • OurDigital Library Software Developer, Brandon Beatty, developed OAI-PMH functionality The code was submitted to the HUBzero development group and added the core HUBzero code. HUBzero now comes standard with OAI-PMH functionality A contribution for the greater good 

17. Metadata Generation Why Premis? PREMIS is a robust preservation standard that captures digital preservation activities applied to a digital object. • Intellectual Entity • Acoherent set of content that is reasonably described as a unit (dataset). • Objects • A discrete unit of information in digital form. • Events • An action that involves at least one object or agent known to the preservation repository. • Rights • Assertions of one or more rights or permissions pertaining to an object and/or agent. • Agents • A person, organization, or software program associated with preservation events in the life of an object.

19. Metadata generation • Why mods? • CaptureDataset Ownership • <name> The name of a person, organization, or event (conference, meeting, etc.) associated in some way with the resource. • <affiliation> The name of an organization, institution, etc. with which the entity recorded in <name> was associated at the time that the resource was created. • <role> Designates the relationship (role) of the entity recorded in name to the resource described in the record. • <accessCondition> Information about restrictions imposed on access to a resource. • <mods:accessCondition type="restriction on access">publically accessible </mods:accessCondition> • <mods:accessCondition type="restriction on access">embargoed until 2015-06-30 </mods:accessCondition>
