• The channelName attribute is a label associated with the subscription that should convey meaning to developer. The channelName is only used as a component in the creation of the event channel identifier. If no channelName is specified the value of "orphan" will be used.
• The namespace attribute is provided as a means for the developer to group subscriptions within a single, or group, or applications. The namespace is used to filter the list of subscriptions returned by the subscriptionList() function. If no namespace is specified the value of "shared" will be used.
• The relationship attribute allows the developer to characterize the relationship between the originator and target clouds. The relationship attribute should be specified as a pair of values separated by a dash (e.g. parent-child, peer-peer, master-slave). The first value of the relationship attribute will be stored with the originating Personal Cloud subscription, the second value will be stored with the target Personal Cloud subscription. The relationship attribute values are used to filter the list of subscriptions returned by the subscriptionList() function. If no relationship is specified the value of "peer-peer" will be used.
• The targetChannel attribute is the event channel identifier (ECI) for the target cloud to which the subscription is to be made. Usually, this is the well-known ECI (doorbell) for the target cloud. The well-known ECI provides a means for bootstrapping subscriptions between clouds.
