You are pretty close. The only thing I would change is the meaning of a
"subproject." I would call your "subproject B" as "task B," and "task
B" has "subtasks". A subtask is just a task that has a task as a parent
node.
I would define a "subproject" as a WBS tree that can be opened in KPlato
by itself, and where the root node would be a subtask in the "main" WBS.
Using your diagramming, which I think is a really clear way to explain this:
Project (WBS Task 1)
|
+-------------+--------------+
| |
|
Task 1.1 Task 1.2 Task 1.3
(Task 1.3 is a sub-project)
|
|
+--------+-------+
+------------+---------------+
| | |
| | |
Task 1.2.1 Task 1.2.2 Task 1.2.3 Task 1.3.1
Task 1.3.2 Task 1.3.3
I think that implementing subprojects might be a bit overwhelming for
early versions of KPlato.
I agree with the analysis that a task class should be created to
encapsulate the calculations. The class should be based on a "general
tree" type of classs.
