Objective: In this paper, we present our findings from an interview-based survey conducted with practitioners working in 18 different companies from 6 European countries. From a practitioner´s point of view, the paper shows what barriers and benefits the management of NFRs as part of the MDD process can bring to companies, how NFRs are supported by MDD approaches, and which strategies are followed when (some) types of NFRs are not supported by MDD approaches. Results: Our study shows that practitioners perceive MDD adoption as a complex process with little to no tool support for NFRs, reporting productivity and maintainability as the types of NFRs expected to be supported when MDD is adopted. But in general, companies adapt MDD to deal with NFRs. When NFRs are not supported, the generated code is sometimes changed manually, thus compromising the maintainability of the software developed. However, the interviewed practitioners claim that the benefits of using MDD outweight the extra effort required by these manual adaptations. Conclusion: Overall, the results indicate that it is important for practitioners to handle NFRs in MDD, but further research is necessary in order to lower the barrier for supporting a broad spectrum of NFRs with MDD. Still, much conceptual and tool implementation work seems to be necessary to lower the barrier of integrating the broad spectrum of NFRs in practice.}, keywords = {}, pubstate = {published}, tppubtype = {article} } Managing Non-Functional Requirements (NFRs) in software projects is challenging, and projects that adopt Model-Driven Development (MDD) are no exception.

Today, we recognize a discrepancy between the early snapshots and their real world correspondents. To overcome this discrepancy, we propose to fully integrate models from the very beginning within the lifecycle of a system. As a first step in this direction, we introduce a data-based model-driven engineering approach where we provide a unifying framework to combine downstream information from the model-driven engineering process with upstream information gathered during a system’s operation at runtime, by explicitly considering also a timing component.

When the IDE targets a graphical language, its development becomes even more complex due to the renderingand manipulation of the graphical notation symbols. To simplify the development of IDEs, the Language Server Protocol (LSP) proposes a decoupled approach based on language-agnostic clients and language-specific servers. LSP clients communicate changes to LSP servers, which validate and store language in-stances. However, LSP only addresses textual languages (i.e., character as atomic unit) and neglects the support for graphical ones (i.e., nodes/edges as atomic units). In this paper, we introduce a novel LSP infrastructure to simplify the development of new graphical modeling tools, in which Web technologies may be used for editor front-ends while leveraging existing modeling frameworks to build language servers.

When the IDE targets a graphical language, its development becomes even more complex due to the renderingand manipulation of the graphical notation symbols. To simplify the development of IDEs, the Language Server Protocol (LSP) proposes a decoupled approach based on language-agnostic clients and language-specific servers. LSP clients communicate changes to LSP servers, which validate and store language in-stances. However, LSP only addresses textual languages (i.e., character as atomic unit) and neglects the support for graphical ones (i.e., nodes/edges as atomic units).
