GenArch+: an extensible infrastructure for building framework-based software product lines

Software product line (SPL) engineering has been focused on tailor single products without programming new completion code. Systematic reuse as configuration potentially lead to significant gains but requires the configuration knowledge to be well conducted. However, due to the use of frameworks to relive the development of software systems, it might become difficult to have precise and comprehensible configuration knowledge specifications. First, because the completion code of a specific framework-provided concept might be scattered across and tangled with code implementing other concepts or features. Second, creating an instance of a framework-provided abstraction involves making implementation choices, some of which are stipulated by hidden programming interface and crosscut heterogeneous languages. In this demonstration we present a tool based on Domain Knowledge Modeling Languages. They are used to express models specifying the configuration knowledge of a specific implementation domain and, ensure the consistency and ease the comprehension of framework-based SPL.
