one, located in the problem space [CZA 00], is related to the
mechanisms the approaches use for expressing variability and
configuring products. The second one, located in the solution
space [CZA 00], is related to the core assets development
and the mechanisms for deriving products. These two aspects
deserve our attention since they are at the core of the research
problems exposed in this topic, which we aim to resolve with
our proposal (Chapter 5).
Figure 8.1. Aspects to review related work regarding
model-driven software product lines
At the end of this section, we present a discussion
emphasizing the advantages and drawbacks of the different
mechanisms used by the presented approaches. We did not
list other valuable references like [ZIA 06, ATK 00, BAY 99,
PUR 10] since they are subsumed by the four presented here,
or are discussed in other parts of this topic, or are commercial
approaches without available full documentation.
