EARL Scenarios

Hi everybody!
I'm Myriam Arrue from the Laboratory of Human-Computer Interaction in the University of the Basque Country. I'd like to start the discussion about the scenarios of EARL.
One of the main objective of EARL is to combine different tools' evaluation results in order to compare them. Another important feature of EARL is that it can be used for exchanging data between tools.
In my opinion, these two objectives can be integrated in a scenario in order to clearly describe to evaluation tools developers the advantages of using EARL as the errors reporting format.
A scenario where a tool or software application invokes different evaluation tools combining the different results obtained in EARL in one complete evaluation result report can be useful for this purpose. This scenario would highlight the need of interaction between evaluation tools and also the importance (as described in Evaluation Suite (http://www.w3.org/WAI/eval/ ) of evaluating the web content with at least two different evaluation tools.
Waiting for your opinions,
Myriam
