 When using a single registry file to represent a logical group of multiple physical entities, make sure the

+For example, if a registry file contains entities with
 id  'light.instance1' and 'light.instance2' the entry for the attribute brightness for these two light instances could
 have "Volttron Point Name" as 'light1/brightness' and 'light2/brightness' respectively. This would ensure that data
 is posted to unique topic names and brightness data from light1 is not overwritten by light2 or vice-versa.
