Which architectural styles?
RQ1: How Software Architecture are being
described?
RQ2: which is the role plaid by MDE in SA
Descriptions?
Keywords:
• Architecture Description
Languages
• Industrial practices
• UML vs formal ADLs
• Needs
• Our solutions:
Interoperability,
megamodeling, DLSs
for domain-specific SA

RQ2: What features
typically supported by
existing ALs are useful
(or not useful) for the

RQ1: What are the main
requirements needed to
build an industrially-
relevant AL?
RQ2: How MDE can
support those
requirements

interoperability
Use of different ALs to model or analyze
different architectural aspects of a system
Bridging the different descriptions to
paramount relevance
Bridging the different descriptions to
be kept consistent and coherent is of
paramount relevance
DUALLY supports interoperability among ADLs.
One model conforming to an ADL, can be
automatically transformed into another model
conforming to a different ADL.

→An MDE framework for customizing existing ADLs
[ICSE2010, ECSA2010]
current ADLs mostly fail to capture multiple
(and varying) stakeholders concerns

• successful adoption of MDE needs a

approach,
– integration with existing
organizational commitments,
– a clear business focus
