These properties are needed to define relatons between slices and predicates, and between predicates and predicates. The position of these declarations in the final user workflow is not yet defined. They could be be specified in the requirements definition phase or interactively during the plan composition.
The scope of these properties is global wrt to any datasets in the process, since they graph elements in order to instruct the operators in the refactoring of the data. The may link elements of the harmonized schema to elements of the source datasets.
