In a world where metadata matters… 2

URS GIBS EMS EOSDIS Discovery Tools DAACs Near Real Time (LANCE) ??? CMR 3

Seriously? Another catalog? 4

No. 5

6

So why are we doing this? 7

Emphasis on Metadata Quality 8

9

Reconciliation Progress and Plans Science Coordinators will assess differences between associated records and work from easiest to hardest with providers Initial pass will associate ECHO 10 Collections with GCMD DIFs Assessment and correlation between ECHO and GCMD holdings has started GCMD is programmatically monitoring ECHO for new Collections and Updates DIF support added to ECHO 10

Handling Metadata Changes Science Coordinator will work with Data Providers to make changes at Metadata source CMR will support pluggable Ingest Adapters to allow in- line updates to ingested metadata if needed Science Coordinator can make updates to metadata on behalf of providers when approved by owner 11

Emphasis on Performance 12

Current Holdings Collections: ~4k + ~24k Granules: ~140M Growth: Current 500k+ granules/week Future ~1 million granules/day during MODIS Collection 6 Reprocessing 13

CMR Transition ECHO components progressively replaced with CMR components Early work to focus on search performance Updated requirements effort starting soon Initial requirements based on MASI and MASII studies CMR will build on ECHO and GCMD capabilities 14

Metadata Concept Support 15

16 Extensibility

ECHO 10GCMD DIFEMS ISO19115 UMM Ingest Adapter VisualizationDocumentationServicesParameters

How Will This Affect Me? 18

Metadata Providers You won’t have to reconcile multiple systems Most systems will continue to work ECHO FTP ingest going away Current formats will continue to function You will need to be engaged in the adaptation process You will need to support controlled vocabularies You will have a voice through the Technical Committee 19 Streamlined Processes, More Engagement

Client Developers 20 More Metadata, Better Quality Richer, higher quality metadata will be available Existing APIs will be supported Standards-compliant APIs will be available Metadata will be available in an ISO19115 compliant format

End Users 21 More Metadata, Better Quality Richer, higher quality metadata will be available Unified view of EOSDIS holdings Easier access through a variety of clients, data casting, etc Metadata will be available in an ISO19115 compliant format

Questions? 22
