The Collection Reference identifies the collection to which the granule belongs. This is done by providing the collection's Short Name and Version Id, or the collection's Entry Title.
It is required that each granule be associated with a parent collection metadata record via the Collection Reference element. This can be done in one of two ways:
Option 1: Provide the collection Short Name and Version.
Option 2: Provide the collection Entry Title.
Example:
Option 1 | Option 2 |
---|---|
Short Name: AST14DEM Version: 003 | Entry Title: ASTER Digital Elevation Model V003 |
Collection Reference is required in the UMM-G (Cardinality: 1). Use option 1 OR option 2.
Option 1:
Model | Element | Type | Constraints | Required? | Cardinality |
---|---|---|---|---|---|
UMM-G | CollectionReference/ShortName | String | 1 - 85 characters | Yes | 1 |
UMM-G | CollectionReference/Version | String | 1 - 80 characters | Yes | 1 |
OR
Option 2:
Model | Element | Type | Constraints | Required? | Cardinality |
---|---|---|---|---|---|
UMM-G | CollectionReference/EntryTitle | String | 1 - 1030 characters | Yes | 1 |
All metadata entering the CMR goes through the below process to ensure metadata quality requirements are met. All records undergo CMR validation before entering the system. The process of QA/QC is slightly different for NASA and non-NASA data providers. Non-NASA providers include interagency and international data providers and are referred to as the International Directory Network (IDN).
Please see the expandable sections below for flowchart details.
