What is it?
  - An RDF-based language.
 
  - Used to produce evaluation reports.
 
  - Evaluate tools or Web content for conformance to a spec 
    (although flexible enough to make claims about other things) 
   
  - Allows us to save information about results from human tests as well as
    tools.
 
  - Allows us to compare those results to determine conformance.
 
  - Developed by the ERT WG (Evaluation and Repair
    Tools WG)
