@namespace(uri="friends", prefix="")
package friends;

@gmf.diagram
class World {
  val Person[*] people;
}

@gmf.node(figure="figures.PersonFigure", 
  label.icon="false", label="name", label.placement="external")
class Person {
  attr String name;
  @gmf.link(width="2", color="0,255,0", source.decoration="arrow", 
    target.decoration="arrow", style="dash")
  ref Person[*] friendOf;
  @gmf.link(width="2", color="255,0,0", source.decoration="arrow",
