Support for dataflows (directed graph of components with input and output ports)

Question

I would like to use plantuml to create dataflows similar to what can be (painly) achieved with:

https://graphviz.org/doc/info/shapes.html#record

The idea would be to declare components and their input / ouput ports first and then to describe how output port of a given component is connected to input of other components.

Ports could be named

Hello J.-M.,

• Is this attempt can answer to your request?

@startuml
[i]
component C {
  portin p1
  portin p2
  portin p3
  portout po1
  portout po2
  portout po3
  file f1
}
[o]

i --> p1
i --> p2
i --> p3
p1 --> f1
p2 --> f1
po1 --> o
po2 --> o
po3 --> o
f1 --> po1

That's great. Is it possible to have port description and name using alias or equivalent.

Something like:

port "port 1" as p1

Yes it is possible, but with some overlapping... as:

component C {
  portin "Port 1" as p1
  portin "Port 2" as p2
  portin "Port 3" as p3
  portout "Port o1" as po1
  portout "Port o2" as po2
  portout "Port o3" as po3
  file f1
}

Regards.
