Question regarding editing of model type

I was going through the model type in ARIS 9 and while editing model type I observed that some model type was having options Select Symbols and Select Connections but few other model types where not having this options.

If I can give an example, if I edit a BPMN Process Diagram 1.x I can edit the 2 options but when checked for BPMN collaboration diagram I couldn't see those options.

Right now I understood that few model type cannot add extra symbols/connections other than the default ones but I don't understand how model types are considered.

I would mostly interested with the BPMN Colloboration 2.0 model type.


Thanks and Regards,

Chethan Rao.

Hello Chethan Rao,

indeed some model types are not as configurable as others. Particularly the BPMN 2.0 model types show a lot of special behaviours you won't find in "normal" ARIS model types. I guess that's why they don't like to find "unexpected" or "unforeseen" elements in them, that would not adhere to BPMN 2.0 standard. The code would not know what to do with them.

The most common use case of changing a BPMN 2.0 collaboration diagram is restricting the available method, thus restricting yourself in the usage of BPMN 2.0. This may be required, if you want to export to some execution environment, which does not support the complete the BPMN 2.0 language specification (hardly any tool does). You would realize such restrictions using the method filter.

If you want to add extensions beyond the BPMN 2.0 standard (e.g. add organizational information to a task), consider function allocation diagrams or other model types using the ARIS "assignment" paradigm. See also chapter 7.2 of the BPMN 2.0 specification about what is not in scope of BPMN.
