PolicyEntry class

A specific Policy for one Entry in the directory or repository.

A policy consists of PolicyGroups and manages the access control to one specific Entry in the S3I-Directory or S3i-Repository. For more background information see: https://www.eclipse.org/ditto/basic-policy.html

In the S3I-Concept there are two special PolicyGroups which have a specific meaning:

owner: An owner has READ and WRITE permission to everything (thing:/, policy:/, message:/)
observer: An observer has only READ permission to the thing part (thing:/)
