Creating a Feature Model

This part of the tutorial will guide you through creating your first feature model.

Edit the Feature Model

Now it’s time to create a feature model specifying the features and their valid combinations.

  1. Step 1: After creating the project, FeatureIDE opens the model.uvl file. A graphical editor displays where you can edit the feature model for your software product line.

  2. Step 2: Create two additional layers under your root feature. Right-click the root feature and select Create Feature (below) twice.

    Rename the first new feature to Hello and the second to World. Rename features using F2, single-click, or right-click with the context menu option.

  3. Step 3: Rename Base to Beautiful and move it between Hello and World. Create a feature named Wonderful and place it between Beautiful and World.

  4. Step 4: Make Beautiful and Wonderful mutually exclusive by selecting both features, creating a new compound feature above them, and naming it Feature. Mark it as abstract from the context menu.

  5. Step 5: Define connection types:

    • And-group: No arc.
    • Or-group: Filled arc.
    • Alternative-group: Unfilled arc.

    In And-groups, children can be mandatory (filled circle) or optional (unfilled circle).

  6. Step 6: Double-click the connection below Feature to change it to an Or-group, then an Alternative-group. Mark Hello and World as mandatory. Click the help button to view the completed model.
