Excerpt of the workflow analysis for the Enzyme Portal. The workflow is a large and comprehensive model of how the user journeys for various personae interact with the Enzyme Portal, and serves to highlight commonalities in behaviour across personae. The thought bubbles indicate the motivation for the user to come to the Enzyme Portal, and the arrows indicate the flow through the layers of the site. The boxes represent individual webpages and list the data items expected to be displayed at each stage of the journey. The complete workflow is available in the Additional file 5.
