Analyze Workflow Summary

This component extracts information from a workflow summary XML file that can be obtained from either the File > Export > Workflow Summary (JSON/XML)… menu in KNIME Analytics Platform, or from a KNIME Server's REST API.

On the KNIME Analytics Platform, a workflow summary is extracted for the currently opened, executed and saved workflow in the workflow editor.

This component extracts the node names, node configurations, predecessor and successor nodes, execution status, node type, if the node is deprecated, and if it’s a metanode/component, names of the nodes and their occurrences, and the reader and writer nodes and the corresponding data locations, into a table representation based on the workflow summary file in XML format. If the “Include execution information“ option is checked when creating the workflow summary XML file, also the execution environment and installed plugins will be provided in the component’s table outputs.

Large workflows with lots of nested components and metanodes will inherently result in large workflow summary XML files. Analyzing such large summaries could take a long time and the resulting tables could be too big. In such cases, limiting the depth of analysis for nested components/metanodes with the component dialog is recommended.
