  1. Katherine Skinner, Martin Halbert & Matt Schultz Educopia Institute and MetaArchive Cooperative The MetaArchive Cooperative:preserving digital memory through distributed digital preservation NDSA Infrastructure Committee 02-17-2011

  2. MetaArchive Cooperative A distributed digital preservation cooperative for digital archives, based on LOCKSS 286 TB network with 24 secure caches Preserving collections for/with 18 members and 46 institutions in 4 countries Actively growing (4 new members this fall, including two consortia with 30 members) Provide preservation consulting and training Skinner, Halbert & Schultz 02/17/11

  3. MetaArchive Cooperative • Founded on the premise that cultural memory organizations should maintain their historical role as cultural stewards • Preservation of digital assets as corollary to preserving physical ones • Need in house expertise and knowledge • Value of curators and librarians and archivists • Chose technical and organizational infrastructure that capitalizes on cultural memory organization’s proven methodologies • Distributed preservation • Partnership to keep costing affordable Skinner, Halbert & Schultz 02/17/11

  4. MetaArchive Basics • Compatible with any repository/content management system • Three membership levels • Preservation members: $3,000K/yr • Sustaining members: $5,500K/yr • Collaborative members: $2,500/yr plus $100/yr per participating institution • Server cost: $4,600/3 yrs • Storage cost: $1/GB/yr Skinner, Halbert & Schultz 02/17/11

  5. Member Responsibilities • Undertake a 3-year membership term; • Take responsibility for content preparation, evaluation, staging, and plugin development; • Host and maintain a MetaArchive cache. Skinner, Halbert & Schultz 02/17/11

  6. Cooperative Responsibilities • Advises, assists, and evaluates member plugins/collections to ensure accurate ingests; • Hosts centralized infrastructure for the network; • Monitors network and content; • Provides ongoing reports to members; • Performs format migrations when needed; • Retrieval of member content on demand Skinner, Halbert & Schultz 02/17/11

  7. MetaArchive Basics: Ingest Producer collaborates with MetaArchive staff to prepare content from any framework (e.g. Dspace, Fedora, CONTENTdm, ETDdb, etc). Producer ingests content into a test network where it is extensively tested for web-crawl accuracy before it is released for production Producer and MetaArchive staff agree that the content is ready for ingest. MetaArchive staff select 7 caches for preservation replications (based on geographical dispersal and space considerations) Each cache regularly returns to the Producer’s master site to ingest new versions as they become available. All versions are preserved.

  8. MetaArchive Basics: Network All caches are connected

  9. MetaArchive Basics: Polling Success = compatible hash value

  10. MetaArchive Services • Data preparation • Replication • Geographical Distribution • Bit Integrity Checking • Versioning • Security • Restricted Viewing • Content Restoration

  11. Trust and TRAC • Completed self-audit with external auditor in 2010 (see http://metaarchive.org/resources ) • MetaArchive successfully conforms in all 3 categories and 84 criteria • “trustworthy digital repository”…ensures that processes and policies and workflows meet the standard for long-term preservation • Helped us identify places where we could improve our policies and documentation Skinner, Halbert & Schultz 02/17/11

  12. OAIS & DDP • TRAC audit also showed us the need for articulating DDP in OAIS terms: • Bridging terminology • Expanding on functional areas • Describing roles and responsibilities • Core topic of PLN 2010 Conference • Working Group formed: Library of Congress, LOCKSS, DataPASS, PeDALS, and MetaArchive Skinner, Halbert & Schultz 02/17/11

  13. OAIS & DDP • Not another Reference Model • Abstraction of OAIS – similar to PAIMAS • Describing a Framework for Applying OAIS to DDP • 1-2 Year Project – Three Phases • Research & Recruitment: GAP Analysis White Paper (OAIS Section 6 & Use Cases) • Production: Collaborative drafting of Framework (modeled on PAIMAS) • Dissemination: Submission to CCSDS and promotion in the DP community Skinner, Halbert & Schultz 02/17/11

  14. OAIS & DDP • Intended Outcomes • Enlarging the community’s understanding of distributed digital preservation concepts & approaches • Guidance on trustworthy digital preservation activities for DDP developers & practitioners • Effectiveness for auditing DDP preservation solutions Skinner, Halbert & Schultz 02/17/11

  15. Sustainability • Balance of flexibility and fragility • Strong organizational center • Limited dependence on any one member • Collaborative model for long-term preservation • Geographic diversity/distribution • Expertise diffusion • Maintain cost-effective, in-house options Skinner, Halbert & Schultz 02/17/11

  16. Preserving our missions • Outsourcing core services = risky proposition • Core missions: • Building collections • Disseminating collections • Preserving collections Cannot focus on the collections at the expense of the services … need both in order to carry our missions and memory forward Skinner, Halbert & Schultz 02/17/11
