International Generic Sample Number

International Generic Sample Number is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand International Generic Sample Number rather than just read about it. In short: The International Generic Sample Number or IGSN is a persistent identifier for a sample. As an active persistent identifier it can be resolved through the Handle System.

Key takeaways

  • International Generic Sample Number belongs to mathematics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect International Generic Sample Number to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of International Generic Sample Number from memory before moving on to harder problems.

Reference excerpt

The International Generic Sample Number or IGSN is a persistent identifier for a sample. As an active persistent identifier it can be resolved through the Handle System. The system is used in production by the System for Earth Sample Registration (SESAR), Geoscience Australia, Commonwealth Scientific and Industrial Research Organisation Mineral Resources, Australian Research Data Commons (ARDC), University of Bremen MARUM, German Research Centre for Geosciences (GFZ), IFREMER Institut Français de Recherche pour l'Exploitation de la Mer, Korea Institute of Geoscience & Mineral Resources (KIGAM), and University of Kiel. Other organisations are preparing the introduction of the IGSN. The IGSN was developed as the International Geo Sample Number to provide a persistent, globally unique, web resolvable identifier for physical samples. IGSN is both a governance and technical system for assigning globally unique persistent identifiers to physical samples. Even though initially developed for samples in the geosciences, the application of IGSN can be and has already been expanded to other domains that rely on physical samples and collections. To take into account the expanded scope of the application of IGSN beyond the earth and environmental sciences, the IGSN Implementation Organization (IGSN e.V.) voted to change the name of the identifier to International Generic Sample Number (IGSN) and rename the organisation accordingly. The IGSN preserves the identity of a sample even as it is moved from lab to lab and as data appear in different publications, thus eliminating ambiguity that stems from similar names for samples from the earth. The IGSN unique identifier allows researchers to track the analytical history of a sample and build on previously collected data as new techniques are developed. Additionally, the IGSN provides a link between disparate data generated by different investigators and published in different scientific articles. In September 2021, the members of IGSN e.V. and DataCite agreed to enter a partnership. Under the partnership, DataCite will provide the IGSN ID registration services and supporting technology to enable the ongoing sustainability of the IGSN PID infrastructure. The IGSN e.V. will facilitate a Community of Communities to promote and support new research and innovation for standard methods of identifying, citing, and locating physical samples.

History The IGSN was developed as part of SESAR with the support of the National Science Foundation at the Lamont–Doherty Earth Observatory. The project was initiated and managed by the Geoinformatics for Geochemistry Program under the direction of Kerstin Lehnert to address data curation obstacles such as different samples that share the same name, and samples that are renamed as they move between laboratories and thus generating analyses that are published under different aliases. As a result, metadata that ensure unique identification are often missing and this causes irritation for future reuse of data from a sample or the sample itself. Sample databases, such as the SESAR database, are designed to address these issues. At a workshop hosted at the San Diego Supercomputer Center in 2011, a group of experts met to discuss how to transition the IGSN project into a sustainable infrastructure. The group recommended opening the system to other IGSN registration agents, making it international and transferring the operation and governance of the IGSN to an independent body. This recommendation led to the foundation of the International Geo Sample Implementation Organization e.V. (IGSN e.V.) and the founding event was held at the American Geophysical Union Fall Meeting 2011 in San Francisco, California. The IGSN e.V. is an incorporated organisation under German law and is registered at the Magistrates Court in Potsdam, Germany. Membership in the organisation is open only to institutions, not to individuals. At present, IGSN e.V. has 16 full members. In 2018, the Alfred P. Sloan Foundation awarded Columbia University's Lamont–Doherty Earth Observatory a grant for a project to modernise the IGSN business model and system architecture. The funding from the Sloan Foundation will support a series of workshops, at which international experts will come together to redesign the IGSN system and its management to allow researchers world-wide use the IGSN with confidence. In September 2021, IGSN e.V. and DataCite entered a partnership under which DataCite will provide the IGSN ID registration services and supporting technology to enable the ongoing sustainability of the IGSN PID infrastructure. The IGSN e.V. will facilitate a Community of Communities to promote and support new research and innovation for standard methods of identifying, citing, and locating physical samples. The partnership allows IGSN to leverage DataCite DOI registration services and to focus community efforts on advocacy and expanding the global samples ecosystem. IGSN and DataCite have a common purpose, and a close relationship in the future will provide mutual benefit to our shared vision of connecting research and identifying knowledge. The partnership brings years of experience across our organizations and communities to scale sample community engagement, develop sample identifier practice standards, and increase adoption globally. In a study published 2023 by Knowledge Exchange it is highlighted that IGSN IDs point to physical objects instead of intellectual property or outcomes (as DOIs mostly do) or their creators. Besides, the report emphasized that the service itself and its organisational framework were developed bottom-up in a sheer community-based effort.

Worked examples

Example 1 — a first encounter with International Generic Sample Number

Start with the simplest possible case. Write down what International Generic Sample Number claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to International Generic Sample Number before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about International Generic Sample Number ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of International Generic Sample Number

In research
International Generic Sample Number appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses International Generic Sample Number in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
International Generic Sample Number is common in secondary-school and first-year university syllabi. It links to neighbouring topics Geochemistry, Unique identifiers, so understanding it makes those chapters shorter.
In everyday life
Look for International Generic Sample Number outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
