  • Keys are like commit in a git repository: they are snapshot of the configuration of all devices in a hutch at a certain point in time. Much like modifying a file generates a new repository state (a "commit") the same does modifying the configuration of a device
  • Each new change of the configuration of the device in a hutch (irrespective of the alias, BEAM or NOBEAM), generates a new key (key numbers are integers increasing with each configuration change)
  • Continuing with the git metaphor, aliases (BEAM, NOBRAM, etc.) are like branches in a repository
