DOI Suffix Model

The following are models for a standard DOI suffix string vocabulary; they will be used as guidance in assigning EOSDIS DOIs. Forward slash is used to represent containment. The purpose is to characterize the data product. 

[mission]/[instrument]/data[m][n]

[campaign]/[platform group]/data[m][n]

[campaign]/[measurement group]/data[n]

[program]/[measurement group]/data[n]

[measurement group]/[data[n]

[instrument]/[shortname.version]

...

.

Keyword "DATA" is placed in the DOI to distinguish raw and processed data collections from research papers.

A sequence number is assigned on a first-come-first-serve basis, represented by [n].
