NASA EOSDIS Data Identifiers: Approach and System.

Area of Science:

• Earth science data management
• Scientific data archiving and distribution

Background:

• NASA's Earth Science Data and Information System (ESDIS) Project initiated DOI exploration in 2010.
• Twelve Distributed Active Archive Centers (DAACs) manage diverse Earth science data products.
• Varied data product generation and archiving processes across DAACs posed challenges for DOI implementation.

Purpose of the Study:

• To investigate and implement Digital Object Identifiers (DOIs) for NASA Earth science data products.
• To develop standardized processes and guidelines for DOI assignment across multiple data centers.
• To enhance data discoverability and citation tracking for Earth science research.

Main Methods:

• Developed processes, guidelines, and models for DOI creation and assignment.
• Utilized the California Digital Library (CDL) EZID service for DOI registration since February 2012.
• Automated the DOI assignment process to improve efficiency and scalability.

Main Results:

• Over 50% of DAAC data products were assigned DOIs by February 28, 2017.
• DOI assignments transitioned from labor-intensive to a rapidly progressing automated system.
• Citations referencing data products using DOIs increased significantly from approximately 100 to over 370 between 2015 and 2016.

Conclusions:

• The ESDIS Project successfully implemented a DOI system for Earth science data products.
• Automation and standardized processes have streamlined DOI assignment and increased data citation.
• The DOI initiative enhances the accessibility and impact of NASA's Earth science data.
