 ** computationModelIds **   <a name="iotsitewise-Type-ComputationModelDataBindingUsageSummary-computationModelIds"></a>
The list of computation model IDs that use this data binding. This allows identification of all computation models affected by changes to the referenced data source.  
Type: Array of strings  
Length Constraints: Fixed length of 36.  
Pattern: `^(?!00000000-0000-0000-0000-000000000000)[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$`   
Required: Yes

 ** matchedDataBinding **   <a name="iotsitewise-Type-ComputationModelDataBindingUsageSummary-matchedDataBinding"></a>
The data binding matched by the filter criteria. Contains details about specific data binding values used by the computation models.
