Hello folks,

I've been playing around the last few days with EARL schema possibilities.  I've gotten rid of blank nodes, which seemed like a good idea.  Is it an improvement?  

Sean and Danbri, Libby said this was "implicit reification."  What are the implications on queries?  I haven't played or thought much about that yet.

I've worked 2 examples. One is a single simple statement, the second combines 2 to make sure that we don't lose important info.

Example 1: Simple statement
success3.svg is the graph produced by the RDF Validator.

   <Asserts>
      <TestSubject rdf:about="http://mypage.org">
         <rdf:type rdf:resource="http://WebContent"/>
         <Result>
            <TestResult rdf:about="http://passes">
               <TestID rdf:resource="http://testid"/>
               <Confidence>High</Confidence>
            </TestResult>
         </Result>
      </TestSubject>
   </Asserts>

Example 2: simple merge
Here is a simple merge of a couple of assertions to make sure we don't lose info.  success4.svg is the graph produced by the RDF Validator.
