Mission: Be a leader in the digital curation research and education fields, and foster interdisciplinary partnerships using Big Records and Archival Analytics through public / industry /government partnerships. Goals: Sponsor interdisciplinary projects that explore the integration of archival research data, user-contributed data, and technology to generate new forms of analysis and historical research engagement. Digital Curation: “personalized access to information, as well as federation, preservation, data lifecycle stewardship, and analysis of large heterogeneous collections, information, and records. ” 2015 NITRD Program Supplement to the President’s Budget

Designing Scalable Cyberinfrastructure Services for Metadata Extraction in Billion-Record Archives NSF: “Brown Dog”, a $10.5M NSF/DIIBs award ( ) -- the “super mutt” of software: –UIUC/NCSA + UMD/DCIC –GOALS: Design & test preservation services in the cloud: DAP & DTS Creating a Big Data Observatory to: –Provide access to big data training sets –Accelerate the development of digital preservation services –

Indigo Peta-scale archival storage and analytics facility, powered by: NetApp storage, Dell computing Open-source Indigo (NoSQL Apache Cassandra): used for long- term archival storage and preservation data C a ve Apache Cassandra (originally developed at Facebook): Adobe, Best Buy, Cisco, Dell, Disney, ebay, FedEx, Netflix, Target, T-Mobile, Travelocity… Scalable to hundreds of petabytes and nodes No external file system (close control of data) P2P – no single point of failure access is available from ANY node, and will delivered from nearest node Data is automatically replicated & compressed Ability to store arbitrary data objects and associated ancillary data ( metadata ) Allows an organization to deposit data objects in a directory tree Deposition/update can trigger arbitrary actions through trigger/rules mechanisms self-managing repositories

Charts can be added to dynamic dashboards

Arrangement can be used as a Facet As you browse the hierarchy... The entire dashboard is redrawn to reflect the particular record group, series or folder under study. “Drill down” or zoom in and out of your collections.

Make comparisons between neighbors Significant Terms are based on full text. They are significant within overall scope of query. Significant Terms can be used to distinguish neighboring folders or documents.
