+This way of expressing stars will have the following features:
+
+1. !ctor & object may be dereferenced by (ap-)api
+2. The activity can be referenced itself (e.g. in order to express a result of the triggered action)
+3. Star is a special case of a Like. Star only happens in ForgeFed context. Different things should be named differnt ...
