Data Lineage View

This component creates interactive visualizations to provide insights about a selected aspect of a workflow and the flow of data within the workflow. It does so by utilizing the Workflow Summary exported as XML file which can be accessed via either the File > Export > Workflow Summary (JSON/XML)… menu in KNIME Analytics Platform, or from a KNIME Server's REST API.

The exported XML first needs to be analyzed by the verified component Extract Workflow Summary whose first output port contains a list of nodes in the workflow and their detailed properties. This component takes this data as input and performs network analysis of the workflow in question and creates different visualizations as a network in which interesting bits and pieces are highlighted. Currently only top level nodes and components are taken under consideration.
