One way to score metrics is by using a script. Below is an example script for scoring a metric. It counts the outgoing serving and access relationships of application components.

forall "ApplicationComponent" app in modelpackage {
   value = 0;
   forall rel in app.relationsFrom() {
      if (rel is "UseRelation" || rel is "AccessRelation") {
          value = value + 1;
   result = Structure();
   result.add("object", app);
   result.add("value", value);
   output result;

For more information about scripting, please refer to the Bizzdesign Scripting Reference.
