stored in DCR. Associated with every device is a unique and immutable
device ID.
•
Group:
Named aggregate entity comprising a set of devices belonging to a single
class or a set of classes, with a common superclass. Groups can be shared
between users or applications, subject to access-control restrictions. The
membership of a group is determined by a rule.

be AND, OR or EXCLUDE.
Group Concept
A group is a named set of devices. The group is characterized by a set of properties
such as an associated rule, name, description, type, and access permission.
The rule determines the membership of a group, which may change whenever the
rule is evaluated. Groups are hierarchical. Groups can be dynamic or static. They
can be Private or Public.
Group Hierarchy
Groups are managed in a hierarchical fashion that supports sub grouping. Each
child group is a subgroup of a parent group, and its group membership will be a
subset of its parent group.
