DataReferenceObject (ProCAKE Framework 4.0.0 API)

All Superinterfaces:

AbstractWorkflowItemObject, DataObject, PropertyHandler

All Known Implementing Classes:

DataReferenceObjectImpl
```
public interface DataReferenceObject
extends AbstractWorkflowItemObject
```
Interface of a reference between a task and a data item. Since July 2012 data references can carry semantic descriptions, which provide additional information when the task uses/produces a data item. This contextual information about the dataitem can be something like the amount of gramm used for this specific task, whereas the general specification of the data item does not contain any quantity-information at all, OR contains a higher quantity.
WFItemID of a DataRef-Object is not used.
