dvName
Unique name of this item's associated DataView definition.
owner

timeStamp
Timestamp of the initial update (seconds since epoch). If the value given is -1.0, the service will populate this field by using correlator currentTime. Note that the default value of the field is 0.0, which prevents trend graphs from updating.

extraParams
