Metadata guide for SESAR Batch Registration SESAR provides services for the registration and unique identification of samples. There are three methods for registering samples in SESAR - Individual Sample Registration, Batch Registration, and registration through our Web Services. This guide is for use in the Batch Registration process. During this process users generate a template for submitting metadata. This guide contains information about the supported metadata fields along with field definitions, controlled or suggested vocabularies, and example entries. For assistance with any of the SESAR registration processes, please contact info@geosamples.org or see our website, geosamples.org.
