  1. PI: Jerry Pan, ORNL Delivering NASA Earth Observing System (EOS) Data with Digital Content Repository Technology: A Software System to Promote Best Practice in Digital Provenance and Effective Access of Content and Associated Metadata • Demonstrate the applicability of a digital object repository technology to science data. • Use this implementation to enable better and more consistent access to data, metadata. • Demonstrate how data providers can more easily and effectively manage science data sets. • Project Success Metrics: An operational Data System based on Fedora Commons Repository system that has • - Successfully ingested the target datasets • - Demonstrated effective data browsing, search, download • - Demonstrated flexible and efficient metadata handling • - Demonstrated system advantages in data preservation • Long-term maintenance plan for the proposed system: continue with ORNL DAAC Project and MAST-DC Project ESDORA: Earth Science Data in Digital Object Repository Architecture • Tested ingestion of datasets with DOI in the object dc:identifier field. Verified that the default indexing and search of Fedora works with the DOI field • Made an analysis of the strength and weakness of Islandoa (see attached document) • Determined that the search and index engine, Solr will perform a more essential role for our solution to work – browsing support will directly come from Solr (faceted search), and a separate Solr engine is needed. • Implemented a new approach w/ prototype for bulk data download from Fedora repository (see attached document) • Made presentations in two technical conferences (OpenRepository 2010, Islandora Summer Camp 2010) • Hired a post-master student (Computer Science), who will start work on the project in ~ 1 month pending on working permit • Work presentation planned for NASA ESDSWG meeting and Fall AGU meeting Co-Is: Chris Lenhardt, Bruce Wilson, Bob Cook, Giri Palanisamy (ORNL) Collaborators: Mark Leggott (UPEI), Sandy Pa Payette (DuraSpace), Sayeed Choudhury (JHU) TRLin=7 TRLout=7 28 June 2010
