    description: A local identifier or name that for the material sample used for
      extracting nucleic acids, and subsequent sequencing. It can refer either to
      the original material collected or to any derived sub-samples. It can have any
      format, but we suggest that you make it concise, unique and consistent within
      your lab, and as informative as possible. INSDC requires every sample name from
      a single Submitter to be unique. Use of a globally unique identifier for the
      field source_mat_id is recommended in addition to sample_name
