This splinter meeting offers an opportunity to discuss and learn about the International Generic Sample Number IGSN and how it can help improve use and utility of physical samples and the data generated by their study. Using the IGSN to identify and cite a sample throughout its life from collection to laboratory to sample archive not only ensures that the sample and the data can be located and linked, but also that the people involved in the collection, analysis, and curation of a sample get the appropriate credit.
