I think there is possibility to map process node types to project node types. For example: task in process -> task in project state -> milestone SubProcess -> SubProject etc. May be another meaning for jPDL nodes should be sufficient. Another issue is how to handle changes in the project plan. e.g. Project plan is A->B->C (token is on node B) would change to /->B->\ A...............|->C \->D->/ and when token should be. and different questions. I will try to specify different tests for such as changes in the project plan. Main difference is, that project has mainly only one instance. If the project is done several times could it be established as process? Could project plan grow to the process graph?
