Element Description

An identifier indicating the level at which the data in the collection are processed, ranging from level 0 (raw instrument data at full resolution) to level 4 (model output or analysis results). The value of Processing Level Id is chosen from a controlled vocabulary.

Best Practices

Issue: need to reconcile processing level enums and decide on best practices

Current enums:

MMT: Not Provided, 0, 1, 1A, 1B, 1C, 1T, 2, 2G, 2P, 3, 4, NA

UMM: https://git.earthdata.nasa.gov/projects/EMFD/repos/unified-metadata-model/browse/collection/v1.10/umm-c-json-schema.json#57 ← enum is not referenced in the UMM-C schema

DIF10: https://git.earthdata.nasa.gov/projects/EMFD/repos/dif-schemas/browse/10.x/UmmCommon_1.3.xsd#432 (same as MMT minus 1C)

ECHO10: no enumeration listed in schema

EOSDIS Processing level Ids: https://science.nasa.gov/earth-science/earth-science-data/data-processing-levels-for-eosdis-data-products/ ← Currently all processing levels in CMR are being humanized to these values. Is this correct?

Some datasets will not fit within the EOSDIS processing level scheme, or the enumerations provided in MMT. (example, ALOS PALSAR level 1.1 and 1.5 data). We should provide guidance to metadata authors on what to do in these cases. If values are getting humanized then we need to provide a mapping table.

Examples:

Element Specification

Model	Element	Type	Constraints	Required?	Cardinality
UMM-C	ProcessingLevel/Id	String	1 - 80 characters	Yes	1
UMM-C	ProcessingLevel/Description	String	1 - 2048 characters	No	0..1

Any values needed for translations?

ARC Priority Matrix

Priority Categorization	Justification
	This element is categorized as highest priority when: The element is not included at all. The element is included but is empty. The processing level for an EOSDIS dataset does not match an EOSDIS processing level. The processing level provided is incorrect for the dataset. The processing level description contains a spelling or grammatical error. The processing level description incorrectly describes the processing level provided.
	This element is categorized as medium priority when: The processing level of a dataset originating outside of EOSDIS does not match an EOSDIS processing level. EOSDIS may re-distribute data from other data providers and the standard EOSDIS processing levels may not apply. A recommendation is made to improve the syntax of the processing level description.
	Not applicable
	The element is provided, and is a formal title for the dataset (i.e. it is not the same as the short name and is free of grammatical and content errors).
