New name for IGSN

A new name, a new role for the IGSN Organization and Identifier

SESAR is an ‘Allocating Agent’ for the IGSN e.V., the implementation organization of the IGSN. We provide IGSNs during the sample registration process, and we maintain the metadata profile pages that an IGSN ‘resolves’ to. In addition to the registration metadata required by the IGSN e.V., SESAR collects and maintains descriptive metadata unique to the SESAR community.

SESAR is excited to share news about some changes to the IGSN e.V.:

The IGSN e.V. Executive Committee announces the new name of the IGSN e.V.: International Generic Sample Number Organization e.V. The new name was approved by the IGSN e.V. General Assembly. The IGSN ID will now be called the International Generic Sample Number to reflect its expanding scope and utilization. Through the partnership between the IGSN e.V. and DataCite, IGSN IDs can now be used in any discipline to identify physical objects.

The mission of the International Generic Sample Number Organization e.V. is to provide guidance on best practices and standards for FAIR samples across disciplines. FAIR samples follow the principles of findable, accessible, interoperable and reusable research resources.

SESAR will continue to provide IGSN registration services as part of our broader suite of services.  As the partnership between the IGSN e.V. and DataCite evolves, we will share any news or impacts with our members.

SESAR v8.0.1 Released

August 2021

SESAR version 8.0.1 is released

On August 26th, we released a new version of SESAR. The release includes an update to our file upload tool. You can review the full list on the SESAR Release Notes page.

If you have questions about SESAR², please contact info@geosamples.org.


SESAR² 8.0.0 Released

July 2021

SESAR² version 8.0.0 is released

On July 22nd, we released a new version of SESAR². The release includes a number of new features, enhancements, and improvements.

We have added a new feature which allows you to login into your MySESAR Dashboard using your ORCiD.  If you have not already, please add your ORCiD ID to your MySESAR profile to use this new feature. We will continue to support GeoPass for shared accounts and for users who do not have ORCiDs. For more information, see our FAQ section on ORCiDs and MySESAR.  

To ensure quality of registered sample metadata, we have added a new feature where new users will need to request access to our Web Services. SESAR² curators will review metadata mapping with new users before permitting access to the Web Services.  Existing accounts do not need to undergo this review.

The release also includes a number of enhancements and bug fixes.  You can review the full list on the SESAR² Release Notes page.

If you have questions or comments about the new capabilities or SESAR² in general, please contact info@54.224.199.193


Recent Change to New SESAR² Namespaces (User Codes)

July 2014

IGSNs are going to change syntax from a 3 digit namespace to a 5 digit namespace (user code), starting with IE (For IEDA, Integrated Earth Data Applications, the facility that oversees SESAR²). This change will accommodate the expansion of IGSN, through the IGSN e.V., to more allocating agents around the world.

A new user will still choose a 3-digit alphanumeric namespace (user code), for example ABC, and their IGSNs will be of the form: IEABC0001, where the first 5 digits are the full namespace and the last 4 digits are alphanumeric. This will give users 36^4 possible IGSNs, or over 1.5 million IGSNs.

This change will not affect existing IGSNs or namespaces (user codes), but will change all namespaces (user codes) and IGSNs allocated by SESAR² in the future.
