In Model-Driven Engineering, the functionality of complex systems lies beyond
the representative capabilities of a single model. Therefore, an increasing variety
of heterogeneous models and languages are used in the various phases of software
development. Information about a system is consequently spread across these
various models with possible overlaps, redundancies, and inconsistencies. To cope
with this complexity, which normally exceeds the cognitive capacity of a single
individual, various approaches have been developed to re-organize information
during systems development.
Different approaches that allow system modelling from various perspectives
or according to separate concerns focus on such diverse issues that it is difficult
to compare and evaluate them. Some of them present solutions for a specific set
of modelling languages or views, but make it hard to assess the applicability in
other scenarios. Others provide means to define new views on models, but do
not consider how redundancy-free models can be established.

Goal
----
The goal of this workshop is to bring together researchers and practitioners
with an interest in model-driven software development to foster a fruitful
cross-pollination of ideas between different communities dealing with the separation
and integration of views or concerns in system modelling. The workshop will prepare
the development of a case-study designed to facilitate the comparison and
evaluation of multi-view modelling approaches and to simplify the identification
of problems that require further research. In break-out sessions requirements for
a common, multi-view modelling case-study will be elicited, possible comparison
criteria will be collected, and ideas for case-study scenarios will be discussed.
In order to provide a foundation for these discussions, we encourage submissions
on new concepts, implementations or formalism as well as submissions
on controversial positions, requirements for a common case-study or case-study
scenarios. Submissions should contribute to investigating and discussing the benefits
and drawbacks of different multi-view modelling approaches or identifying
best practices.

Topics
------
The workshop is interested in submissions that prepare a common, multi-view
modelling case study and in submissions on all topics related to model-driven development
that deal with the separation and integration of different perspectives,
languages, abstractions, views or concerns. More specifically, this includes:
- bridging the gap between different views or metamodels,
- generating, defining and evolving different views, models and metamodels,
- round-trip engineering and co-evolution of different models,
- composition of different views, models and metamodels,
- (bidirectional) transformations of metamodels,
- avoiding inconsistencies, overlap and redundancies between modelling artefacts,
- generating models and metamodels for multiple views or formalisms,
- separating and re-integrating cross-cutting concerns or model weaving,
- dynamic information hiding for partial views

Contributions
-------------
Submissions to the workshop are possible in three categories.
Research papers should describe original work on a problem or solution that
pertains to the systematic separation or integration of models, concerns, views,
or other modelling artefacts on six to eight pages.
Position papers should present a well-defined position on how various modelling
languages, viewpoints, heterogeneous subsystems, or concerns should be
handled in MDE on two to four pages.
Case-study papers should discuss requirements, criteria, or scenarios for a
common multi-view modelling case-study for comparing and evaluating different
approaches on two to four pages.
All paper submissions have to adhere to the ACM SIG Proceedings Style (alternate
format).
