General Board / Re: Data objetc reuse in BPMN?

Hi QWERTY,
I seem to remember that BPMN is not a profile or 'dialect' of UML although it looks similar to activity diagrams.  I think it has different origins (graphical programming using service classes or some such...).  I'm sure other experts can comment (I only know a little because I had to learn it for a project but did not continue using it after that)

Aleksi, I seem to remember from when I was learning BPMN that you can sort of map the messages of BPMN to data structures (I seem to remember that it was not an exact mapping, but again I'm no expert...).  I'll ask some people more knowledgeable than me... I'll post again if I get an answer!

Hello Aleksi
if you use UML sequence diagrams instead of BPMN to model your processes, the sequence diagram participants can be data objects.  It's super-easy to a) reuse these participants to generate new business processes, b) generate an object (or class) diagram showing the data structures that support your processes, c) use the class diagram to design a database if you need one to support the processes, and d) use the class diagram to write application software if you need one.

What I'm saying is, BPMN can be tweaked to do what you want to do, but it was not designed to be used this way.  For more info you can see the OMG web pages on BPMN (=a process-centric notation, not an object oriented notation).

Cheers

Richard

EA 13.10

Hello I am playing around with MDG to customise the toolboxes of standard UML profile (by removing the toolbox elements that I don't use).

I use the MDG Technology Builder to create the xmi files for toolboxes and diagram types for several UML diagrams (Class, Use Case etc.).  My MDG files create correctly and show in both the Resouces / MDG technologies / Import technology as well as in the Configure / Technology / Manage menus.  However sometimes the "Set active" button remains grayed out even if I restart EA.  In this case I cannot access the MDG.

Question 1. Does anyone have any good guess of common reasons why the enable button is grayed out?
Question 2. I assume that to change the toolboxes I don't need to redefine extensions of the UML standard elements / connectors and diagrams... just define the new toolboxes using the profile helper.  Is that correct?   
Question 3. When using the helper, is it better to have a separate eap project file for each toolbox or to have all in one eap file?  If all in one file, what is the right package structure (I remember the user manual saying stereotype packages cannot be nested)?  I am trying this package structure:
-  Model
  - Sparx Helper
     - Component profile
        - Component  diagram profile (I edit the toolbox attribute, then I save this package as a profile)
        - Component diagram toolbox (I edit this, then I save this package as a profile)
        - Component toolbox profile
     - Use Case profile
        - Use Case diagram profile (I edit the toolbox attribute, then I save this package as a profile)
        - Use Case diagram toolbox (this is the part I edit, then I save this package as a profile)
        - Use Case toolbox profile
      - Etc. etc.

Thank you very much!

Hello Sylvain,

if you need to define a package structure to organize your enterprise model, can I recommend that you google "Zachman Framework" and read anything you can find written by John Zachman.  You can buy books or get certified if you want, but it's not necessary to benefit from this.

You can also buy the Zachman Framework MDG from Sparx.  It's overkill for me and I don't use this MDG but I think it will create the package structure and model organization that you want.

Personally I just make my own Zachman-like package structure as follows (as others already pointed out, just use "View" packages for everything, they are just packages).  Each line below is a package; ">" shows the level of nesting.

Root element - XYZ enterprise model
> Context
> Concept
> Logical
> Physical
> Out of context

Inside each of above package, I have these sub-packages:
>>Data
>>Function
>>Motivation
>>Network
>>People
>>Time

Each new project has its own totally separate package containing diagrams that I created for that specific project.  Whenever I create a new element (Actors, Use case, Class etc.) I either reuse or create it in one of the Zachman-like packages.  This way I quickly build up a useful repository of enterprise elements that not only describe the enterprise, they also accelerate modeling for each successive project.

Hope this helps!

Richard

I can't believe it worked!  First don't autohide then hide... thank you very much madam/sir.

YES!  Thank you!!

Hello

my screen real estate is at a premium so in order to maximize workspace I'd like to remove/completely hide the "Start" navigation pane located at the far right of the screen.  The pane closes automatically and has an "Options" menu to rearrange items, but even when closed it takes up a few pixels that I want to use.  Does anyone know if there is a way to totally hide it, similar to the way the status bar can be removed from the screen?  Thanks!

Thank you Uffe and QWERTY,  but that is exactly where I'm stuck.  I can't find out how to make a new toolbox because the default UML profile is not available in the MDGTechnologies folder; also I cannot access its Toolbox Profile diagram. 

I can find the list of default toolboxes in the documentation, but not the list of their elements (with exactly correct element names).  So I don't have a standard toolbox profile that I could edit, and I can't make a new one from scratch either.

Thank you very much VKN!!  I tried it and as you say, EA does not make a difference between a Tagged Value "memo" type and a tagged value note (I assumed they would be different things, i.e. a "memo" type tagged value could have its own separate note).  Misleading, but easy to correct.  Thanks again!!

Hello

EA version 1310

to make a lot of conceptual/logical level diagrams quickly, I want to create custom toolboxes for the main UML diagrams in the standard EA UML profile (class, use case, sequence, etc.).  But the default UML profile is not available in the MDGTechnologies folder and most documentation is about how to ADD new toolboxes for a new technology, not how to REMOVE elements to the existing toolboxes for the EA default UML profile.

Can anyone point me to instructions to do this?  Thank you very much!!

EA 1310.

I want to export a CSV report listing names and tagged values for some elements. I use the Publish / CSV exchange specification menu to make a file specification including fields "Name" and tagged value "Remarks", which is a memo type tagged value.

When I run the CSV report, everything works correctly except all the "Remarks" fields are blank.

If the "Remarks" tagged value is NOT "memo" type then the fields are not blank and all entries are visible in the exported CSV file.

My current workaround is to make 'Remarks" a normal tagged value then enter the text in the notes field of the Remarks tagged value; then select Tagged value notes in the CSV exchange specification. But I think it would be better if "memo" type tagged values exported to CSV correctly. Is this a bug?  Should I file bug report?  Thanks!!
