Review: Propagation model

I have been running this workflow as part of a learning curve in the use of Taverna in heliophysics. I used the cut and paste method from the URL given on the myExperiment page into the Taverna workbench. The workflow ran very nicely and is well documented on the myExperiment site so that it is clear what the inputs and ouputs refer to. It is a nice evocation of the Trinity College propagation model which is a good example of how to present an application as a web service.
