MetaModel SequenceDiagram [message #472796]

Hello NG,
at first I want to say sorry for my bad English.
Well, let's go. I work with a UML-Modeling-Tool. Therefore I'm writing a
script to export a Model(consisting of Class Diagram, StateCharts,
UseCases and Sequence Diagrams) to the Eclipse ecore-UML format. So I
installed the Eclipse-Plugin "Topcased" to research the Syntax and
MetaModel of ecore-uml. For Class Diagrams and StateCharts it worked
fine. But I for SequenceDiagrams I had some problems, because I couldn't
see if it was only the solution of the author of "Topcased" or if it is
valid to the Eclipse-MetaModel for SequenceDiagrams. What I mean is, do
I need such elements like "Connector" or "Behaviour Execution
Specification" as they are generated by "Topcased"? Therefore I'm asking
if there is an Eclipse-MetaModel. Surely there is - but where?
Could you understand me?

greets
Jan R.

Hi Jan

The UML specification can be found at : http://www.omg.org/docs/ptc
To my knowledge, Connectors are not required when specifying sequence
diagrams but are handy to have especially when specifying Communication
diagrams which can be derived from the sequence diagram.
The creation of BehaviorExecutionSpecifications would depend on the sequence
diagram in question.
Sequence Diagrams can be "loosely" described so it is possible to have
different looking diagrams that describe the same thing. For example, the
order of the lifelines on a diagram could be completely jumbled from one
depiction to the next and still be correct ... isn't UML great!

Hi Jan,

As a contributor in the Topcased project, I would definitely recommend
you to read the UML Superstructure and UML Infrastructure
Specifications. (Follow the link pointed by James).
In the Sequence Diagram, we tried to use the concepts as they are
defined in these documents but the specification is often not clear,
especially concerning the diagramming elements.

Regards,
Jacques
