Overview
Currently, there is no native support for unique identifiers in vtk/ParaView. There are many issues that relate to this.

Pedigree ID
A pedigree ID is defined as the ID which relates input objects to output objects. It is used to follow the 'pedigree' of an object. This ID is applied by a filter, in a way defined by its operation. Two examples illustrate its use.
Definition A Pedigree ID is copied from parent to child.
=Source ID
Definition If, in the input data set, there is an identifier for the object (such as the GlobalElementID in Eoxuds), this data is retrieved from the file as the Source ID.
Threshold
A Threshold filter removes certain filters from a vtkDataSet.
