Element Description
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.
Best Practices
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.
- Short Name: The collection's short name per the UMM-C.
- Version Id: The collection's version per the UMM-C.
Option 2: Provide the collection Entry Title.
- Entry Title: The collections entry title per the UMM-C.
- Entry Title: The collections entry title per the UMM-C.
Example:
Option 1 | Option 2 |
---|---|
Short Name: AST14DEM Version: 003 | Entry Title: ASTER Digital Elevation Model V003 |
Element Specification
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 |
Metadata Validation and QA/QC
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).
