Element Description
The PGE Version Class element stores basic descriptive characteristics related to the Product Generation Executable (PGE) associated with a granule. PGE refers to software used to produce a standard data productsproduct.
Best Practices
There are two sub-elements that comprise PGE Version Class:
- PGE Name: The name of the product generation executable.
- PGE Version: Version of the product generation executable used to produce the granule.
Providing the PGE Version Class is optional. If provided, the Version number must be included - providing the PGE Name remains optional.
Examples:
PGE Name: "MOD_PR10A2_8day_snow_cover_tile"
PGE Version: "6.0.27"
PGE Name: "OMCLDO2 Level 2"
PGE Version: "2.0.0.9"
Element Specification
The PGE Version Class element is optional. Only one PGE Version Class may be provided (Cardinality: 0..1)
Model | Element | Type | Constraints | Required? | Cardinality |
---|---|---|---|---|---|
UMM-G | PGEVersionClass/PGEName | String | 1 - 1024 characters | No | 0..1 |
UMM-G | PGEVersionClass/PGEVersion | String | 1 - 10 characters | Yes, if applicable | 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).
