Discussion
There are also alternative definitions of "node" fashioned for specific applications of its use that have been defined in standards below:
(1) In a diagram, a point, circle, or other geometric figure used to represent a state, event, or other item of interest. (ISO/IEC/IEEE 24765:2010 Systems and software engineering--Vocabulary)
(2) Configuration of engineering objects forming a single unit for the purpose of location in space, and which embodies a set of processing, storage and communication functions. (ISO/IEC 10746-3:2009 Information technology -- Open Distributed Processing -- Reference Model: Architecture, 8.1.7)
(3) Modeled function located within the hierarchical graph structure of an IDEF0 model by its designated node number. (IEEE 1320.1-1998 (R2004) IEEE Standard for Functional Modeling Language - Syntax and Semantics for IDEF0, 2.1.80)
(4) One of the defining points of a schedule network; a junction point joined to some or all of the other dependency lines. (PMI 2008)
(5) Vertex of a net graph, i.e., a place or a transition. (ISO/IEC 15909-1:2004 Software and system engineering -- High-level Petri nets -- Part 1: Concepts, definitions and graphical notation, 2.1.16.2)
