Relational networks can be drawn in either compact or narrow relational network notation. Narrow notation shows greater detail. All lines in narrow notation are one-way.

Narrow network notation allows more precision in describing nections. In narrow notation, connections are directed, so the nection boundary may be precisely located. Each external connection then is defined to be part of its source nection, but not of its destination nection.

Narrow notation also allows definition of a possible node structure for nodes which in compact notation look but aren't simple.


Here is an ordered AND in narrow notation:


Here we also see the use of inhibitory blocking elements, which are a special type of junction node.
