The International Geo Sample Number or IGSN is a sample identification code of typically nine characters. 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, Curtin University John de Laeter Centre for Geochemistry, and University of Bremen MARUM. Other organisations are preparing the introduction of the IGSN. 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. == 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. 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 to open the system to other IGSN registration agents, make it international and transfer the operation and governance of the IGSN to an independent body. This recommendation lead 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.〔http://www.igsn.org〕 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 15 full members.〔List of full members in the IGSN e.V.: http://dokuwiki.gfz-potsdam.de/datawiki/doku.php?id=igsn:statutes#full_members〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「International Geo Sample Number」の詳細全文を読む スポンサード リンク
