tern modeling notations. These support pattern-based
model evolution where patterns are used as transfor-
mation rules to support model evolution. We primar-
ily focused on utilising experimentally identified pat-
terns that facilitate a first class abstraction to reusable
change execution. This enables fine granular change
operationalisation that can be parameterised to guide
potentially reusable evolution in architecture-centric
models. It is vital to mention about a catalog of pro-
cess change patterns (Weber et al., 2007) that guides
changes in process-aware information systems. In
contrast to the process aspects of a software, we ex-
clusively focus on change operationalisation at archi-
tectural abstraction levels accommodating patterns to
guide structural evolution.
5 CONCLUSIONS AND
OUTLOOK
We propose to leverage architectural change mining
- identifying patterns from change logs - to support
potential reuse during architecture evolution. We
demonstrate that if an architectural evolution prob-
lem can be specified declaratively, pattern-driven evo-
lution could relieve an architect from the underlying
operational concerns for executing routine evolution
tasks that exist in catalogue.
In future, we are primarily concerned about ex-
plicitly addressing the granularity of change execu-
tion that goes beyond generic specifications of iden-
tified patterns. We focus on structural modifications
to the internal architecture of composite components
guided by change patterns that is currently lacking in
our solution. Additional case studies in (Gruhn et al.,
1996) and (Javed et al., 2009) shall allow a more rig-
orous evaluation in terms of a solution that facilitates
the notion of ‘build-once, use-often philosophy’ to
evolve architectural models.
