; Invocation links : An invocation link connects a source process to the destination process that it initiates.

# ''Process invocation'': Process invocation is an event of triggering of a process by a process. An invocation link is a link from an invoking process to the process that it invokes (triggers), meaning that when the invoking process terminates, it immediately triggers the process at the other end of the invocation link. Graphically, a lightning symbol jagged line from the invoking process terminating with a closed arrowhead at the invoked process end denote an invocation link. The syntax of an invocation link OPL sentence is: Invoking-process invokes invoked-process.

# ''Self-invocation link'': Self-invocation is invocation of a process by itself, such that that upon process termination, the process immediately invokes itself. The self-invocation link shall denote self-invocation. Graphically, a pair of invocation links, originating at the process and joining head to tail before terminating back at the original process denote the self-invocation link. The syntax of a self-invocation link OPL sentence is: Invoking-process invokes itself.

# ''Implicit invocation link'': Implicit invocation occurs upon sub-process termination within the context of an in-zoomed process, at which time the sub-process invokes the one(s) immediately below it. Graphically, there is no link between the invoking and the invoked sub-processes; their relative heights within the in-zoom context of their ancestor process implies this semantics.
