ABSTRACT
Software Product Lines can be briefly defined as a family of products
that share some commonalities. The feature models approach is
used to represent the commonalities and variabilities among products.
One possible way for the construction of these models is the
use of meta-models. However, the management of these features,
traditionally performed at development time, is not sufficient for
the development of Adaptive Systems. One solution to this type of
development is the approach of Dynamic Software Product Lines
which has as one of its aims to promote features input and output
at runtime allowing the product to be adapted after changes in
contexts. This article proposes a Domain Specific Modelling Language
that aims at modeling Dynamic Software Product Lines. This
language describes dynamic adaptations promoted at runtime and
through the use of the state machine approach. Such adaptations,
based on state machines, must promote state features changes or
features exchanges at runtime, enabling these software products to
manage derivations in its life cycle. Our proposal was implemented
with the use of a Healthcare scenario and its development was
based on the concept of the component service model.
