NASA's Common Metadata Repository (CMR) is a high-performance, high-quality, continuously evolving metadata system that catalogs all data and service metadata records for NASA's Earth Observing System Data and Information System (EOSDIS) system and will be the authoritative management system for all EOSDIS metadata. These metadata records are registered, modified, discovered, and accessed through programmatic interfaces leveraging standard protocols and APIs.

For more information on the CMR, please see the CMR Earthdata Homepage .

Unified Metadata Models (UMM)

UMM is an extensible metadata model which provides a cross-walk for mapping between CMR-supported metadata standards. Rather than create mappings from each CMR-supported metadata standard to each other, each standard is mapped centrally to UMM, thus reducing the number of translations required from n x (n-1) to 2n.

UMM - Collections (UMM-C)

UMM - Granule (UMM-G)

UMM - Services (UMM-S)

UMM - Variables (UMM-VAR)
