ADVANCING REPRODUCIBLE SCIENCE FROM PHYSICAL SAMPLES: IGSN AND THE ISAMPLES RESEARCH COORDINATION NETWORK (Invited Presentation)
The International Geo Sample Number (IGSN) is a persistent identifier for physical samples. Its adoption by individual investigators, repository curators, publishers, and data managers has been growing rapidly world-wide, and use of IGSN for sample citation is now recommended by major journals in the Earth sciences. The IGSN implementation organization IGSN e.V. has members in 4 continents, and 5 Allocating Agents in the US, Australia, and Germany are registering samples for their user communities. Recent achievements include the development of the IGSN metadata schema for describing samples with a set of properties that describe a sample’s origin and classification in a “birth certificate” for the sample; the prototype of a central IGSN metadata catalog that harvests descriptive metadata from OAI-PHM providers at IGSN Allocating Agents, and Linked Data patterns for IGSN metadata.
The Internet of Samples in the Earth Sciences (iSamples) is an initiative funded as a Research Coordination Network within the EarthCube program to better connect physical samples and sample collections across the Earth Sciences with digital data infrastructures to revolutionize their utility for science. Several working groups within iSamples have created a wide range of resources from metadata schemas to educational materials that support this mission. A major focus of iSamples for the next phase will be the preservation and access of the actual physical samples for re-use.
