The CMR will be merging the metadata holdings of two existing catalogs, GCMD and ECHO. All EOSDIS DAACs currently submit and maintain metadata about their archives in both of these systems.
In the current paradigm, sometimes the metadata submitted to both systems is maintained by a single team within the DAAC's organization and is largely kept in sync, while in other instances two separate teams submit and maintain this metadata.
The reconciliation efforts being organized by ESDIS are attempting to document and analyze current holdings in both ECHO and GCMD, as well as plan for unifying of these collection level holdings into the CMR.
Expand the panel to view two diagrams outlining the current and future metadata flow.
