About NASA GSFC 2 n NASA Goddard Space Flight Center (GSFC) is located in Greenbelt, MD. n One of 13 NASA Centers n Mission: Expand knowledge of the Earth and its environment, the solar system and the universe through observations from space n GSFC currently has over 40 missions in orbit, over 10 missions accomplished, and over 15 missions under research and plans for orbit. at the Goddard Library

Scope n n 3 Digital Asset System n The Framework n Internal Library Project Information Project Collaboration n Hitchhiker n Swift n Landsat at the Goddard Library

Digital Asset System n n n A metadata/institutional repository to describe and provide access to project information including images, videos, web sites, and technical reports. Framework and methodology for customizing each project while maintaining consistency. Internal Library Information n Used across all project resources developed by the Goddard Library n n n 4 Increases search precision Project Inheritance Consistent Database Structure at the Goddard Library

DAS Framework Project Scope Audience Content Types Formats Ingest Process Elements Qualified GC GC Extensions Administrative Extensions 5 Submission vs. Harvesting/Spidering Content Guidelines Constraints: Pick lists Input Rules Mandatory/Optional Input order at the Goddard Library

Metadata n Project Metadata n n n Identify metadata used in source project library Map the project library metadata to the Goddard Core n n n 6 Extends the Dublin Core to 24 qualified descriptive elements. There additional Administrative Elements. Preservation Elements are being developed Extends to accommodate GSFC project specific needs such as taxonomies and controlled vocabularies Organizes and manages content across collections and formats Allows for re-use & re-purpose of all content types in collections Aids long term preservation and access at the Goddard Library

Taxonomy/Controlled Vocabulary n n NASA Taxonomy developed by NASA Jet Propulsion Laboratory (JPL) serves as the primary taxonomy for the Digital Asset System Project-specific taxonomies/controlled vocabularies added: n n n 7 Earth Observing System (EOS) Landsat Swift Benefits of incorporating a known knowledge base for project community Assist in browse and navigation across broad collections of various object types at the Goddard Library

Project Collaboration n 8 Swift n Landsat n Mission Status: Operational since 2002 n Mission Status: Operational since 1972 n Project Library: Yes n Project Library: No n Presentation medium: DAS Sub-system n Presentation Medium: DAS Sub-system n Content n Document Pointers n Documents n Web Sites n Video Histories n Photographs n Web Sites n Videos (Interviews) at the Goddard Library

Swift Metadata Repository SMR search results by content type “still image” and Document Pointer 9 at the Goddard Library

Landsat Legacy System Landsat Legacy Search Results and Project Document Metadata Record in the NASA Look and Feel 10 at the Goddard Library

Accessing Project Information Improved resource discovery through DAS Framework across 7 project resources 11 at the Goddard Library

The Power of the DAS Repository Framework 12 n Communication across projects n Enriched findability of project information across projects and agencies n Helps ensure individual project and DAS requirements are met n Allows for extending and tailoring for internal and external project information at the Goddard Library
