Separate link between components (aka data link) and link between subjob (trigger)

We currently have one kind of link to link two components together. Then, we add data into this link in order to specify it?
However, we can describe two mains families the link that contains data and the link that do not.
The first family (data link) will transmit data to the next components, the second one (trigger) will schedule the different part of a job.

If we want to make complex algorithm on the graph of components, we really need to separate the two kind of link, in order to ease any future development.

Data link:

FLOW
MAIN
REJECT

Trigger:

ITERATE
SUBJOB_OK
SUBJOB_ERROR
COMPONENT_OK
COMPONENT_ERROR
RUN_IF
