   We evaluate Validity as follows:
   
  +[.text-center]
  +=====================================================================
   Validity = 40 * Cool URI Score + 60.0 * Linked Data Rule Score

positive.code: 
  We assume the execution time as:
  
  Execution Time = Differences of the response time for those queries.
  
  After that, we evaluate Performance as:
  
  Performance = latexmath:[\left\{
      \begin{array}{ll}
          100.0 * (1.0 - {\rm Execution~Time}) & {\rm if~Execution~Time~is~less~than~1~second} \\
          0 & {\rm Otherwise}
      \end{array}
      \right.]
  
negative.code: format, otherwise false. We access the endpoint URI via HTTP with the
  following HTTP Request Header:
  +
  =====================================================================
  Accept: text/turtle,application/rdf+xml
  =====================================================================
  * VoID
  +
  true if VoID can be retrieved from well-known URI in Turtle format or
  RDF/XML format, otherwise false. We access the endpoint URI via HTTP
  with the following HTTP Request Header:
  +
  =====================================================================
  Accept: text/turtle,application/rdf+xml

  We calculate Operation score as follows:
  
  [.text-center]
  =====================================================================
  Operation = latexmath:[\left\{
