Year 2 Scenario Proposal : Year 2 Scenario Proposal Simple scenario illustrates an interface to allow users to define computational pathways
Behind the scenes, DOCKER uses descriptions of components and their constraints (developed in Year 1) to:
detect errors in user’s input
suggest additional steps needed to make the pathway work
make educated guesses about how components selected by the user may be connected to one another

Ontology server PWL Query Answer
User is Done Defining Pathway, System is Aware of Additional Requirements : User is Done Defining Pathway, System is Aware of Additional Requirements System knows to setup a loop to iterate IMR over Eqks in EFM (by setting up a 'set reformulation')
System knows to ask for a span (needed to setup EFM Step) that the user did not mention
System generates details required to run on the Grid
New Capabilities : New Capabilities System uses descriptions of components and their constraints (available in DOCKER) to:
detect errors in user’s input
suggest additional steps needed to make the pathway work
make educated guesses about how components may be connected
possibly generate Grid execution script
