Query
Constraint?
...
Version number of the attribute. This number is automatically incremented each time the value changes.
No historical data is persisted. Only the last value is persisted.
...
No. You can request the value
using Format on <Find>
...
1457663102004 is same as Fri, 11 Mar 2016 02:25:02 GMT
Note that this is only the "Create" timestamp. If attributes are updated their timestamp do not change.
...
Fully qualified name of the attribute. <NamSpace>.<Domain>.<ModelName>.<AttributeName>. For example
SimpleModel.MyModels.VendorInfo.vendorName given that VendorInfo is defined withinNamespace - SimpleModel, with Domain as MyModels and DataModel Name as VendorInfo
...
Applicable to ThingFacet/AppFacet. Known is the value that is set within the Action. Known can not be
set using Create / Update TQL Query by the user.
...
2016-03-10 18:25:02.004 Note that is is only the "Create" Datetime. If attributes areupdated their datetime value do not change.
