  • Sampling Metadata from the Common Metadata Repository
Skip to end of metadata
Go to start of metadata

In order to evaluate the completeness and consistency of metadata in the Common Metadata Repository (CMR) we created a sample of collection and granule metadata by identifying collections with one or more granules and selecting the collection records in four dialects (DIF9, DIF10, ECHO10, and ISO19115-2). We also selected the most recent granule from these collections in ECHO10 and ISO19115-2. These records were downloaded during the first half of March, 2016.

Collection Metadata - March 2016
