Semionic Network

A Semionic Networks (SNs), see below, is a Semionic System with some topological restrictions given by the addition of two types of passive entities: places and arcs.

 

 The topological restrictions says respect to two main points, directly related to the enabling and generative scope:

Place: be a class C. A place Õ is defined as a passive entity that contains zero or more objects (active or passive) of the same class C.  Besides, if C goes an active class; it is said that Õ is an active place, case contrary a passive place, see below.

Arc: is defined as a connection between an output gate (linked to the origin place) and an input gate (linked to the destiny place), see below.

Gate: are classified in two orthogonal characteristics, see below. The first one - and the simplest - refers to the direction of the flow of information; be entering or leaving the place, see above. The second one indicates as the objects are inserted or removed of the place.

 In the internal behavior of a gate two different possibilities are present: 

From the superficial conceptualization of an arc and of the characterization of the types of gates is derived a more detailed classification of type of the possible arcs. Two combinations are just considered valid:  

 Other combinations of gates are:  

The difference between publics-privates and public-public arcs can be understood better from the illustration below. It illustrates all the four possible combinations of gates.
