The basic objects include individuals, times, places, labels, situations, relations, and parameters. Situations are first-class citizens which represent limited portions of the world. A situation cannot support both an infon and its dual. A situation can contain infons which have the former as arguments. Information flow is made possible via coercions that link various types of objects.
Parameters are place holders and can be anchored to unique individuals in an anchoring situation.
The anchoring situation is required to cohere. A situation can be realized if its parameters are anchored, either partially or fully, by an anchoring situation. That is, only anchoring the parameters of an infon contributes a piece of information about the situation. The basic computation regime is unification. A hierarchy of situations can be defined both statically and dynamically.
