Encoding feature models using mainstream JSON technologies

Abstract

Feature modeling is a process for identifying the common and variable parts of a software product line and recording them in a tree-structured feature model. However, feature models can be difficult for mainstream developers to specify and maintain because most tools rely on specialized theories, notations, or technologies. To address this issue, we propose a design that uses mainstream JSON-related technologies to encode and manipulate feature models and then uses the models to generate Web forms for product configuration. This JSON-based design can form part of a comprehensive, interactive environment that enables mainstream developers to specify, store, update, and exchange feature models and use them to configure members of product families.
