Enhanced PerformanceModern Earth Science applications strive to provide end users with nearly immediate access and interactivity across massive stores of Earth Science data. That data is discovered, navigated, and often interrogated through science metadata. As the range of applications grow and more and more information moves from the underlying science data to metadata, the challenges of navigating even just the metadata increases. CMR is designed to handle hundreds of millions of metadata records; making them available through high-speed performance, standards compliant, temporal, spatial, and faceted search. The CMR builds on the work done by ECHO and the GCMD to provide a unified, authoritative repository for NASA's Earth Science metadata. End-User Interface Diagram Quality AssuranceHigh performance access to metadata is only part of the problem. To be useful to a broad range of Earth Science applications, the metadata must be of high quality, complete, and consistent. The CMR incorporates both human and machine metadata assessment features that work to ensure the highest quality metadata possible. During ingest, automated metadata scoring rubrics are applied giving data providers insight into how to make their data more discoverable or usable by end users. Science Coordinators and review teams can review metadata that fails verification or lacks required information to help providers make their metadata more consistent and complete. Metadata Quality Assurance Diagram Consistent Metadata Representation- The CMR's ingest adapter framework supports pluggable adapters which validate distinct metadata formats such as ECHO10, GCMD DIF, and ISO19115 against a common set of core metadata requirements, the Unified Metadata Model (UMM).
- The CMR will be able to take multiple metadata records associated with a common core concept, such as a Collection, and merge the disparate information into a robust and standards compliant ISO19115 representation for interested clients.
- As additional metadata concepts are introduced to the CMR, new ingest adapters will provide verification and search indexing capabilities across diverse metadata such as visualization and parameter information.
