In recent years, MDA and associated MDE methodologies, approaches and languages emphasized the role that OCL has to play in MDE development. But beyond using OCL in specifying assertions and operations, new approaches and visions reveal beneficial usage of OCL to specify model behaviour, non-functional properties, compilation and evaluation of models, model transformation, and code generation. All these usages concern using OCL with other modelling languages in general, and UML in particular for modelling systems with OCL.

This workshop solicits research contributions and experience reports related to the adequacy of OCL for systems modelling, OCL refactoring and extensions in order to support new usages of OCL specifications and new application domains.

Topics of interest include (but are not limited to):

• OCL as a textual formalism for specifying (meta-)models and systems
• Use of OCL in Domain Specific Languages (DSLs)
• Use of OCL in specifying model behaviour. Extensions required for this usage. Examples of applications
• Using OCL expressions in specifying aspects
• OCL usage for navigating and querying models and databases
• OCL as a neutral standard for specifying multi-tier applications
• OCL and Model Transformations. Needed extensions.
• Using OCL specifications in meta-modelling. Completeness and correctness of well-formedness rules
• OCL and business process modelling
• OCL and ontology modelling
• Experience reports
• OCL Tools supporting, e.g., model compilation and execution

Papers which do not fit any of the topics above, but are relevant to the goals of the workshop are also welcome.

The workshop will include short (about 15 min) presentations, parallel sessions of working groups, and sum-up discussions. Accepted papers will be made available on the workshop web page well before the workshop. In addition, it is planned that polished versions will be published by an international publisher.

Full papers should be 5--15 pages in length in LNCS style. Papers must be submitted by email in PDF format to Steffen.Zschaler (at) tu-dresden.de.

The program committee will review the submissions and select papers according to their relevance and interest for the discussions that will take place at the workshop.
