Topcased is an “integrated System/Software engineering toolkit compliant with the requirements of critical and embedded applications”.

We are mostly interested in the subproject TOPCASED-UML2 which is the only stable and free Eclipse-based UML Editor which supports UML-Profile creating and application compatible with Eclipse 3.5.

Download the latest Eclipse Modeling distribution ¹⁾.

1. Go to http://www.eclipse.org/downloads/
2. Choose the download of “Eclipse Modelling Tools” that matches your platform.

3. Open the installation dialog with “Help » Install New Software”.

4. Copy

http://topcased-mm.gforge.enseeiht.fr/release/update-site3.5/

to the Working with field and press ENTER

5. Install Topcased UML Editor and Topcased Dependencies from the Topcased Toolkit section.

1. To create a (profile) diagram select File→New→“New UML model with TOPCASED”
2. Your file names must end with .profile.umldi and .profile.uml respectively.
3. Read pages from 7-12 Topcased UML Feature Tutorial

To set the stereotype's meta-class add a meta-class element to the diagram and assign a uml classifier (e.g. Class, Association, Operation, CallBehaviourAction,…) to it. Then add an Extension connection from your stereotype:

To add a Property²⁾ to your stereotype, click first on the Property item in the panel and then onto the target stereotype. Assign a type to the Property. Ideally use uml::XX primitive types (e.g. uml::Integer), otherwise the property might not be available in the applying uml diagram if the type is not imported there:

The properties are not visible/editable in the UML Diagrams themselves, but in the Properties view when selecting a classifier (Class, Activity,etc.). You can open the Properties view by pressing Ctrl-3 and typing “Properties”.

Be aware: It is not possible to edit a profile an applying model document at the same time with topcased editors. The editor for the later opened file will be opened read-only.

• After modifying an UML-Profile you must
  1. define the profile: right-click on the root element (<Model>) in the outline (in the latest version you are asked for re-definition on every save)
  2. re-apply the profile in all UML diagrams already using the profile: right-click on the root element (<Model>) in the outline, select apply an add the profile in question

Open the editor's outline and right-click on the element to constraint. Add a Constraint child:

Select the constraint, open the Properties view ³⁾, select the Specification tab on the left and add the language OCL⁴⁾. Now you can add on ocl constraint by clicking “create OCL expression”:

• The promising MDT UML2 Tools can not be considered complete, yet (Jan. 2010). Setting stereotype properties are not supported, yet. And all diagrams, except class diagrams, are only rudimentary implemented.
