/** @defgroup DSCOV Data Sharing - Change of Value Service (DS-COV)
|
|
* @ingroup DataShare
|
|
* 13.1 Change of Value Reporting <br>
|
|
* Change of value (COV) reporting allows a COV-client to subscribe with a
|
|
* COV-server, on a permanent or temporary basis, to receive reports of some
|
|
* changes of value of some referenced property based on fixed criteria.
|
|
* If an object provides COV reporting, then changes of value of any
|
|
* subscribed-to properties of the object, in some cases based on programmable
|
|
* increments, trigger COV notifications to be sent to subscribing clients.
|
|
* Typically, COV notifications are sent to supervisory programs in COV-client
|
|
* devices or to operators or logging devices. Any object, proprietary or
|
|
* standard, may support COV reporting at the implementor's option.
