2 05/10/20102 About the MDI Workshop Interoperability is the ability of separate entities, systems or artifacts (organizations, programs, tools, etc.) to work together. Although there has always been the need to achieve interoperability between heterogeneous systems and notations, the difficulties involved in overcoming their differences, the lack of consensus on the common standards to use and the shortage of proper mechanisms and tools, have severely hampered this task. Model-Driven Engineering (MDE) is an emergent discipline that advocates the use of (software) models as primary artifacts of the software engineering process. In addition to the initial goals of being useful to capture user requirements and architectural concerns, and to generate code from them, models are proving to be effective for many other engineering tasks. New model-driven engineering approaches, such as model-driven modernization, models-at-runtime, model-based testing, etc. are constantly emerging. Model interoperability is much more complex than simply defining a local serialization format, e.g., XMI. This would just resolve the syntactic (or plumbing) issues between models and modeling tools. However, interoperability should also involve further aspects, including behavioral specifications of models (which in turn describe the behavioral aspects of the systems being modeled), and other semantic issues such as agreements on names, context-sensitive information, agreements on concepts (ontologies), integration conflict analysis (including for example automatic data model matching), semantic reasoning, etc. Furthermore, interoperability not only means being able to exchange information and to use the information that has been exchanged, but also to exchange services and functions to operate effectively together. Models and MDE techniques (especially metamodeling and model transformations) can play a fundamental role for fully accomplishing these tasks. Thus, models can become cornerstone elements for enabling and achieving interoperability between all kinds of systems and artifacts, including data sets (under the presence of different data schemata, and possibly at different levels of abstraction), services (despite their differences in data representation, access protocols and underlying technological platforms), event systems (with different complex types and origins), languages (that use different notations and may have different semantics), tools (with different data formats and semantic representations), technological platforms (with different notations, tools and semantics), etc. Interoperability is the ability of separate entities, systems or artifacts (organizations, programs, tools, etc.) to work together It is our claim that Models and MDE (esp. metamodels and transformations) can play a key role for enabling and achieving interoperability between systems, artifacts, functions, services, platforms and tools. Interoperability goes beyond a common serialization format (e.g., XML or XMI): Names, protocols, behavior and semantics need to be agreed

3 05/10/20103 Scope of the workshop The goal of this workshop is to discuss the potential role of models as key enablers for interoperability, and the challenges ahead. It aims to provide a venue where researchers and practitioners concerned with all aspects of models and systems interoperability could meet, disseminate and exchange ideas and problems, identify some of the key issues related to model-driven interoperability, and explore together possible solutions.

4 05/10/20104 Topics for the workshop Precise specification of models, metamodels and their properties. Precise notations of compatibility/composition of models and metamodels (for, e.g., DSL combination). Automated tool support for constructing, analyzing, comparing and composing models. Definition of underlying formal frameworks that allow automated reasoning about model interoperability. Requirements for interoperability: challenges and roadmap. Tool metamodeling. Use of existing MDE technologies for interoperability (model transformation, model weaving, model differencing, model evolution, …). Analysis of current standards and proposals for extensions to standards to enable interoperability. Industrial and experience reports on interoperability. Architectures for MDI. Integration between Business and IT models. Model transformation for Semantic Interoperability. Ontological and semantic support for MDI. Reverse engineering of Information Systems and MDI. Taxonomy of interoperability problems and solutions. Methods and support for achieving interoperability through models.

6 05/10/20106 Model Driven Interoperability MDE is a new technology New technologies usually add to the heterogeneity of legacy systems But MDE is not only a technology to be integrated with others … MDE is also an integration technology

7 05/10/ Integration Integration (from the Latin integer, meaning whole or entire) generally means combining parts so that they work together or form a whole. In information technology, there are several common usages: Integration during product development is a process in which separately produced components or subsystems are combined and problems in their interactions are addressed. Integration is an activity by companies that specialize in bringing different manufacturers' products together into a smoothly working system. (WhatIs def.) Integrate Make working together, in a whole corresponding to a precise objective, elements that were not initially designed to achieve this objective. Exemple: Enterprise Application Integration (EAI) The process of adapting a system to make applications work together when they would otherwise be incompatible.

8 05/10/20108 System Integration system integration: The progressive linking and testing of system components to merge their functional and technical characteristics into a comprehensive, interoperable system Note: Integration of data systems allows data existing on disparate systems to be shared or accessed across functional or system boundaries.

9 05/10/ Data Integration A broad spectrum of data is available on the Web in distinct heterogeneous sources, stored under different formats. As the number of systems that utilize this data grows, the importance of data conversion mechanisms increases greatly… A key observation is that, often, the application programs used by organizations can only handle data of a specific format... To enable a specific tool to manipulate data coming from various sources, a translation phase must take place…The naive way to translate data from one format to another is writing a specific program for each translation task… A sound solution for a data integration task requires a clean abstraction of the different formats in which data are stored, and means for specifying the correspondences between data in different worlds and for translating data from one world to another.
