How can I create a reference to another plantuml file in Activity Beta Diagram?

Question

To modularize my diagrams I want to refer to other diagrams. Thus I want to create a reference or a link behind a node element in the activity beta diagram type. When clicking on the node element the linked diagram should open.

How can I do this?

Hello B.,

For that you can use links and SVG output (which manages natively links), like:

A parent file named "Diagram.puml":

@startuml
start
[[Init.svg]]:Initialisation;
:[[Process.svg Processing]];
stop
@enduml

Then 2 files (on the same folder as the first diagram, for this example) named "Init.puml" :

@startuml
:read config file;
:init internal variable;
@enduml

and "Process.puml"

@startuml
:Action 1;
:Action 2;
@enduml

1. Export all the diagrams on SVG, 
2. then browse the first parent diagram ('Diagram.svg')
3. and follow the different links to navigate on the other diagrams...
4. Enjoy...
