Abstract

NASA’s Earth Science Data and Information System (ESDIS) Project began investigating the use of Digital Object Identifiers (DOIs) in 2010 with the goal of assigning DOIs to various data products. These Earth science research data products produced using Earth observations and models are archived and distributed by twelve Distributed Active Archive Centers (DAACs) located across the United States. Each data center serves a different Earth science discipline user community and, accordingly, has a unique approach and process for generating and archiving a variety of data products. These varied approaches present a challenge for developing a DOI solution. To address this challenge, the ESDIS Project has developed processes, guidelines, and several models for creating and assigning DOIs. Initially the DOI assignment and registration process was started as a prototype but now it is fully operational. In February 2012, the ESDIS Project started using the California Digital Library (CDL) EZID for registering DOIs. The DOI assignments were initially labor-intensive. The system is now automated, and the assignments are progressing rapidly. As of February 28, 2017, over 50% of the data products at the DAACs had been assigned DOIs. Citations using the DOIs increased from about 100 to over 370 between 2015 and 2016.

Author Biographies

Lalit Wanchoo, Adnet Systems

Lalit Wanchoo is Task Lead with Adnet Systems, Inc and supports Earth Science Data and Information System (ESDIS) Project at NASA Goddard Space Flight Center through its contract with Adnet Systems. His work is focused on Earth science data applications, data usage, product metadata practices, data citations, and developing and implementation procedures and guidelines for registering identifiers. He received the Master of Science degree in Agricultural Engineering from the University of Maryland

Nathan James, Earth Science Data and Information System Project (Code 423), NASA Goddard Space Flight Center

Nathan James serves as a Science Data Systems Engineer for the Science Operations Office of the Earth Science Data and Information Systems (ESDIS) project at NASA Goddard Space Flight Center. He is primarily responsible for planning and managing the science data system capabilities for archiving, processing, and distributing Earth science data products. He also manages the development and implementation of NASA’s EOSDIS Digital Object Identifier (DOI) system designed to address the need for persistent identifiers and the promotion of data citations across ESDIS’s 12 discipline-oriented active archives of Earth science data. Nathan oversees the Citations and Identifiers Working Group, one of NASA’s several Earth Science Data System Working Groups. He holds a Bachelor of Science degree in Computer Science from the University of Maryland, College Park.

Hampapuram K. Ramapriyan, Earth Science Data and Information System Project (Code 423), NASA Goddard Space Flight Center

Hampapuram Ramapriyan is a Research Scientist/Subject Matter Expert at Science Systems and Applications, Incorporated (SSAI). He supports the Earth Science Data and Information System (ESDIS) Project at NASA Goddard Space Flight Center through its contract with SSAI. The ESDIS Project is responsible for archiving and distributing most of NASA’s Earth science data using the Earth Observing System Data and Information System (EOSDIS). Ramapriyan’s primary focus is data stewardship and preservation. Prior to his employment with SSAI, he was the Assistant Project Manager of the ESDIS Project. His responsibilities included management of Science Investigator-led Processing Systems that processed and delivered data to the EOSDIS Distributed Active Archive Centers (DAACs). He has been an active member of the Citations and Identifiers Working Group, one of NASA’s several Earth Science Data System Working Groups. He has also been an active member of the Federation of Earth Science Information Partners (ESIP) since its inception in 1998. He has led development of the emerging Provenance and Context Content Standard and its adaptation to NASA’s Earth Science Data Preservation Content Specification. He is currently the Vice-Chair of the ESIP Data Stewardship Committee and Chair of the Information Quality Cluster. He holds a Ph. D. degree from the University of Minnesota.
