Tool Overview

We have developed a tool (FMView) to support our idea of refining feature model with updatable view. FMView is a prototypical implementation and we are developing it within Eclipse as a Plug-In. You can download the tool here.

Here we provide a Demo to illustrate the tool and the basic idea of our approach.

 

Demo

First you can construct your feature mdoel in FMView. In this demo, a feature model with 18 features are built using our tool, as shown in the figure.

Original Feature Model

 

In this demo, 3 initial features are selected to indicate the interest of the domain enginner. These initial features are filled with green.

Initial Features in the Feature Model

 

Based on the initial features, the original feature model is sliced into a comprehensible view, as shown in the right part of the figure. Annotations, artificial
features and artificial refinements are added to help domain engineer understand the view.

A View of tthe Feature Model

 

FMView mantain the traceability links between the model elements in the view and the model elements in the original feature model.
In this demo, features K, L, Q, R and the relationships between them are selected in the view, the corresponding features and relationships are automatically
highlighted with red, as shown in the left part of the figure.

Traceability between the Feature Modell and the View

 

In FMView, modifications on the view can be reflected to the original feature model automatically.

In this demo, feature O, P and the require constraint between features K and L are deleted in the view. The corresponding features and constraints in the
original feature model are deleted (colored with orange) automatically.
Two new features, S and T ,are added as the children of feature K in the view, these modifications are reflected to the origianl feature model (colored with
purple) automatically.
In the view, feature R is renamed with R'. In the original feature model, the corresponding feature is also renamed (colored with blue) automatically.

Modification and Reflection

 

To make the refined original feature model more clear, FMView can hide the deleted features in th refined original feature model. In this demo, the deleted
feature S and T are hidden in FMView, as shown in the left part of the figure.

Modification and Reflection

 

Inner Model Representations

We use GRoundTram, which has been developed to support systematic development of bidirectional model transformation, to build FMView. GRoundTram
adapts an existing well established graph querying language UnQL for model transformation. In GRoundTram, graphs are edged-labeled in the sense that all
information is stored as labels on edges rather than on nodes. The GRoundTram system gives a support to construct an updatable view, maintain the
traceability between the feature model and the updatable view.

We represent, in GRoundTram, feature models and views by graph models. Please refer to here for the representations of feature models in the GRoundTram.
