The Common Metadata Repository (CMR) catalogues all data and service metadata records for the EOSDIS system. These metadata records are registered, modified, discovered, and accessed through programmatic interfaces leveraging standard protocols and APIs.

The Unified Metadata Model is a model that encompasses various metadata profiles maintained and archived by EOSDIS. The UMM will be used by the Common Metadata Repository and will drive search and retrieval of metadata cataloged within that system.
More details: First a link to a presentation: AGU Fall 2014 - Streamlining Metadata in NASA EOSDIS CMR To increase the level of quality and consistency among its metadata holdings, EOSDIS has developed (and continues to develop and expand) a model for various metadata profiles that it archives and maintains. This model aims to document vital elements that may be represented across various metadata formats and standards and unify them through core fields useful for data discovery and service invocations. This unified model, aptly named the Unified Metadata Model (UMM), has been developed as part of the EOSDIS Metadata Architecture Studies (MAS I and II) conducted between 2012 and 2013.
The UMM will be used by the Common Metadata Repository (CMR) and will drive search and retrieval of metadata cataloged within that system.
All UMM profiles will be mapped to the ISO 19115 metadata model as shown in the diagram below. Image Removed
The UMM is managed as a series of documents, each covering a subset of the entire UMM. The UMM documents are listed on the UMM Documents page. An overview of the UMM can be seen by clicking on the box below UI Expand | | |||||||
