2.2.1 Devices By Direct Access :< BASE_URI>/Devices
The resulting payload from this API is slightly different that the payload returned by the other device-
related REST API calls. After all devices are enumerated in the resulting XML payload, two additional pieces
of information are returned as well:
• AddedOrUpdatedTimestamp
• DeletedTimestamp
The AddedOrUpdatedTimestamp and DeletedTimestamp denote the latest timestamps associated with
the device payload just returned. These timestamps can be used to retrieve delta information by a
consumer.
For example, if the device listing was retrieved by an OME REST consumer at time t1 and the consumer
needs to get information about the devices that were added or modified or deleted at time t2 where t2 >
t1, then the consumer, using the AddedOrUpdatedTimestamp and DeletedTimestamp obtained from the
last call at t1, can get a list of only the changed and deleted devices using the following REST API:
