Overview

Questions

• How can we expand to a multi-step workflow?

• Iterative workflow development

• Workflows as dependency graphs

• How to use sketches for workflow design?

Objectives

• graph objectives:

• explain that a workflow is a dependency graph

• sketch objectives:

• use cwlviewer online

• generate Graphviz diagram using cwltool

• exercise with the printout of a simple workflow; draw arrows on code; hand draw a graph on another sheet of paper

• iterate objectives:

• recognise that workflow development can be iterative i.e. that it doesn’t have to happen all at once

By the end of this episode, learners should be able to explain that a workflow is a dependency graph and sketch their workflow, both by hand, and with an automated visualizer and recognise that workflow development can be iterative i.e. that it doesn’t have to happen all at once.
