  To obtain an IGSN, users need to register a sample by submitting information about it to an IGSN Allocating Agent.  Once logged in, users can:
  * register individual samples or batches
  * register sampling features
  * track relationships between samples and subsamples (e.g., bulk samples and mineral separates)
  * update information on registered samples
  * download QR code images for labelling purposes
