This page describes the process of registering/reserving DOIs with ESDIS as well as updating a DOI. Recommendations for the structure of a DOI can also be found on this page and what should be assigned a DOI can also be found here.
ESDIS DOI Registration Process
Step 1: Data Provider interested in registering DOIs, please visit ESDIS DOI wiki for DOI related information: (http://earthdata.nasa.gov/wiki/main/index.php/DOIs_for_EOSDIS). Access to wiki is restricted to registered users only. Users need to register with Users Registration System. To register, please visit URS at https://urs.eosdis.nasa.gov/ and sign up for an account.
Step 2: Contact ESDIS DOI Staff to review the procedure for developing DOIs, review a DOI model that will suit data provider’s data products, review the EZID registration process and required metadata, go over any questions or clarification. ESDIS can setup a teleconference with the data provider staff for this step.
Step 3: Data Provider to make final selection of a DOI model and generating DOIs with the metadata as required by EZID (refer Table 1). If Data Provider would like ESDIS to develop DOIs then Data provider should provide list of data products with metadata information to ESDIS and ESDIS will generate DOI list.
Step 4: Data Provider to send the DOI list to ESDIS for feedback.
Step 5: Once the DOI and related information is finalized, ESDIS will reserve or register DOIs with the EZID based on the completeness of the DOI’s metadata information.
The ESDIS DOI Registration Process is explained in more detail in the diagram below.
Automatic Processing Description
ESDIS has recently upgraded the DOI registration system from a manually-driven to one that largely automates the DOI process. The new automated feature include: a) reviewing the DOI metadata, b) assigning of opaque DOI name if data provider chooses, c) reserving, d) registering, and e) updating the DOI information. The flexibility of reserving the DOI allows data providers to embed and test the DOI in the data product metadata before formally registering with EZID. The DOI update process allows the changing of any DOI metadata except the DOI name unless the name has not been registered.
ESDIS DOI Metadata Update Process
This update process is applicable to all fields except DOI. If a data product is generated with a new software version then a new DOI needs to be registered.
Step 1: Data provider to provide the revised information for DOIs to ESDIS. The fields that can be revised are listed in Table 2.
Step 2: ESDIS will review the revised information and provide feedback to the data provider.
Step 3: Once revisions are finalized, ESDIS will update DOI with the EZID.
DOI Naming Convention
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]
10.5067/[opaque-id]
In the above syntax, the processing level of the product is depicted by [m] where ‘m’ ranges from 1 through 3 for products from satellite instruments. (i.e., NASA satellite products are generally depicted as belonging to a Level of processing, Level 1 being calibrated/geolocated radiances through Level 3 being global grids of derived geophysical values). When a Level designation isn’t appropriate [m] is dropped from the syntax.
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].
A few examples include:
- Aura HIRDLS level 2 data product
- 10.5067/Aura/HIRDLS/DATA201
- MEaSUREs GSSTF Level 3 data product
- 10.5067/MEASURES/GSSTF/DATA301
- Aura AMSR-E data product
- 10.5067/AMSR–E/AE_OCEAN.003

Roles and Responsibility
Three organizations are involved in the registering EOSDIS DOIs.
EZID is the service provider and provides ESDIS access to DOI handling system 24 hours a day and 7 days a week to register and modify DOIs. In addition, keeps ESDIS updated with the any changes/updates to the DOI data model or services that are offered by EZID.
The DAAC is the content provider and usually the publisher of the data product that is assigned a DOI. They are responsible to provide ESDIS with the data product metadata via the DOI Submission Form, develop and maintain data product related landing page, and assist ESDIS in DOI maintenance by providing ESDIS any changes in the product metadata or landing page URL.
ESDIS is the registration service provider and is responsible for managing the “uniqueness” of DOIs when creating them. DOIs assigned by ESDIS through EZID will always begin with the prefix 10.5067. ESDIS also provides guidance to the data provider in developing a DOI identifier suffix, reviewing the DOI name and metadata for its completeness, assigning DOIs to the products if requested, reserving DOIs, registering DOIs, and updating DOIs. ESDIS maintains a list of all products with DOIs that have been registered or reserved with the project.
To submit DOIs for registration for EOSDIS supported projects, contact Nate James (nathan.l.james@nasa.gov) and Lalit Wanchoo (lalit.wanchoo-1@nasa.gov).
