“…We have concretely implemented the conceptual approach described in Section 3 by relying on EMF [28] as our core Modeling Framework. Based on our own knowledge and expertise, we made the choice of using EMF Views [6] as our Model View Framework. Concerning the Persistence Frameworks, we used both NeoEMF [10] and CDO [14] as supporting graph and relational database backends (respectively).…”

“…These can be seen as kind of equivalent to a (partial) support for model views. Compared to our solution based on EMF Views [6], Epsilon does not currently provide optimized strategies to heterogeneous backend queries, nor allows to decorate multiple models/metamodels. Moreover, it only relies on in-memory structures to store both the merging and decoration constructs, which can be a limitation in terms of scalability.…”

When engineering complex systems, models are used to represent various systems aspects. These models are often heterogeneous in terms of modeling language, provenance, number or scale. They can be notably managed by different persistence frameworks adapted to their nature. As a result, the information relevant to engineers is usually split into several interrelated models. To be useful in practice, these models need to be integrated together to provide global views over the system under study. Model view approaches have been proposed to tackle such an issue. They provide an unification mechanism to combine and query heterogeneous models in a transparent way. These views usually target specific engineering tasks such as system design, monitoring, evolution, etc. In our present context, the MegaM@Rt2 industrially-supported European initiative defines a set of large-scale use cases where model views can be beneficial for tracing runtime and design time data. However, existing model view solutions mostly rely on in-memory constructs and low-level modeling APIs that have not been designed to scale in the context of large models stored in different kinds of sources. This paper presents the current status of our work towards a general solution to efficiently support scalable model views on heterogeneous model resources. It describes our integration approach between model view and model persistence frameworks. This notably implies the refinement of the view framework for the construction of large views from multiple model storage solutions. This also requires to study how parts of queries can be computed on the contributing models rather than on the view. Our solution has been benchmarked on a practical large-scale use case from the MegaM@Rt2 project, implementing a runtime -design time feedback loop. The corresponding EMF-based tooling support and modeling resources are fully available online.• Software and its engineering → Model-driven software engineering; Abstraction, modeling and modularity; • Information systems → Database design and models;

When engineering complex systems, models are typically used to represent various systems aspects. These models are often heterogeneous in terms of modeling languages, provenance, number or scale. As a result, the information actually relevant to engineers is usually split into different kinds of interrelated models. To be useful in practice, these models need to be properly integrated to provide global views over the system. This has to be made possible even when those models are serialized or stored in different formats adapted to their respective nature and scalability needs. Model view approaches have been proposed to tackle this issue. They provide unification mechanisms to combine and query various different models in a transparent way. These views usually target specific engineering tasks such as system design, monitoring, evolution, etc. In an industrial context, there can be many large-scale use cases where model views can be beneficial, in order to trace runtime and design-time data for example. However, existing model view solutions are generally designed to work on top of one single modeling technology (even though

In today's engineering projects, companies continuously have to adapt their systems to changing customers or dynamic market requirements. This requires a flexible, iterative development process in which different parts of the system under construction are built and updated concurrently. However, concurrent engineering becomes quite challenging in domains where different engineering artifacts from different disciplines come into play, such as safety‐critical cyber‐physical systems, where the involved engineering artifacts are quite heterogeneous in nature. In such systems, it is of utmost importance that different artifacts remain consistent in order to guarantee a correctly functioning end product. In this article, we discuss our experiences (with a leading company working in the areas of production automation and product processing) in maintaining the consistency between electrical models and the corresponding software controller, when both are subject to continuous changes. The article discusses how we let engineers describe the relationships between electrical models and the corresponding software controller code in the form of links and consistency rules. Additionally, we demonstrate that how our approach, through a process of continuous consistency checking, notifies engineers about the erroneous impact of their changes in various engineering artifacts.
