About

Software-intensive systems are complicated, driven by the need to integrate across multiple concerns. Consequently, the development of such systems requires the integration of different concerns and skills. These concerns can be covered by different domain-specific modeling languages, with specific concepts, technologies, and abstraction levels. This multiplication of languages eases the development related to each individual specific concern but raises language and technology integration problems at the different stages of the software life cycle. To reason about the global system as a whole, it is necessary to explicitly describe the different kinds of relationships that exist between the different languages used in its development. To support effective language integration, there is a pressing need to reify and classify these relationships, as well as the language interactions that the relationships enable. Equally, the proliferation of domain-specific modeling languages required increases the need for effective and efficient techniques for engineering languages and their support infrastructures (transformations, analysis tools, editors, execution infrastructure, debuggers, …).

The Modeling Language Engineering (MLE) workshop aims at bringing together researchers and practitioners working on modeling-language and software-language engineering. It is a meeting opportunity for Software Language Engineering (SLE) enthusiasts within the software-modeling community.

Keynote

Engineering Families of Modelling Languages: A tale of three approaches (slides)

Abstract: Modelling languages are intensively used in paradigms like model-driven engineering to automate all sort of tasks within the development process. These languages may have variants (like the cases of Petri nets, automata, architectural languages, and many others) in which case, there is the need to deal with language families rather than with individual languages. Moreover, low-code approaches aim at lowering the entry barrier to software development, frequently via the use of modelling notations. Users of low-code environments have a wide range of backgrounds, which calls for specialized language variants, tailored to users with different levels of expertise. However, from a language engineering perspective, specifying the syntax and semantics of each language variant separately is costly, hinders reuse across variants, and may yield inconsistent semantics between variants. In this talk, I will introduce three different approaches to tackle this problem, based on multi-level modelling, superimposed language variants, and language modules. I will discuss the weak and strong points of each one of them based on a practical case study and propose challenges for future work.

Prof. Juan de Lara is full professor at the computer science department of the Universidad Autónoma of Madrid (Spain), where he leads the modelling and software engineering research (miso) team together with Esther Guerra. His main research interests are in automated software engineering, model-driven development, domain-specific languages and language engineering, conversational interfaces, and augmented reality. This research has led to building many practical tools – including AToM3, metaDepth, merlin, alter, DSL-comet, DSL-tao and Capone– and the publication of more than 230 papers in international journals and conferences. He has been the PC co-chair of several conferences within his research areas, like MODELS, SLE, ICGT, ICMT and FASE, and has been involved in workshops on topics like flexible modelling, multi-level modelling and low-code development.

Session chairs

The organizing committee of MLE 2022 is unfortunately not able to be physically present at MODELS 2022. Therefore, exceptionally, MLE 2022 will be presented by three voluntary session chairs from the MLE community:

Call for papers

Topics

The topics of interest for MLE 2022 include:

  • Methodologies, languages, techniques, and methods for designing and implementing modeling languages
  • Composition, extension, and reuse of modeling languages and model execution tools
  • Heterogeneous modeling, simulation, and execution
  • Customization of modeling languages
  • Integration of modeling languages and programming languages
  • Semantics-aware model transformations and code generation
  • Scalability of model execution and execution-based model analysis
  • Execution of partial and underspecified models
  • Model execution in the presence of non-determinism and concurrency
  • Tracing model executions and analyzing model execution traces

  • Live modeling and exploratory modeling techniques
  • Automation techniques for the development of modeling and model execution tools
  • Evolution in the context of executable modeling (e.g.} evolution of executable modeling languages, execution semantics, executable models, model execution tools)
  • Verification of semantic conformance (e.g., among executable modeling languages, executable models, model execution tools)
  • Integration challenges for languages, from requirements to design, for analysis and simulation, during runtime, etc.
  • Case studies and experience reports on the successful or failed adoption of modeling in different application domains and application contexts
  • Surveys and benchmarks of different approaches for the development of modeling languages, model execution, and execution-based model analysis

Submissions describing practical and industrial experience related to the use of modeling languages are also encouraged, particularly in the following application domains: Cyber-Physical Systems, Smart Manufacturing, Industry 4.0; Internet of Services, Internet of Things; Smart City, Smart Building, Home automation; Smart and Learning systems.

Workshop Format

This full-day workshop will prioritize discussions over presentations. We plan to open with a keynote in the morning, followed by paper presentations. The afternoon will then be spent primarily in discussions inspired by topics raised by the keynotes and paper presentations. Where there is sufficient divergence in the topics raised, we will create break-out groups of participants interested in each sub-topic. The goal of these discussions is to identify commonalities and connections between different topics, support research networking, cross-pollination, and informal knowledge transfer. The final session of the workshop will be focused on summarising the key topics and ideas discussed at the workshop to help identify the next steps that may be followed up by workshop participants.

Submission

We expect early research results about the aforementioned topics, descriptions of problems, case studies, experience reports, or solutions related to the topics of interest.

Each contribution must be described in a short paper of 5 pages or a full paper of 10 pages, in ACM format (acmart). Two more pages containing only references are permitted.

Papers that describe use cases or novel approaches can be accompanied by concrete artifacts, such as models (requirements, design, analysis, transformation, composition, etc.), stored in a public repository. Artifacts should illustrate any experience with the conjoint use of different modeling languages.

All submissions have to follow the ACM format (acmart) and must be submitted electronically in PDF format via Easychair. They will be evaluated by at least three members of the program committee regarding novelty, correctness, significance, readability, and alignment with the workshop call. Furthermore, all submissions must be original work and must not have been previously published or being under review elsewhere. The accepted papers will be included in the joint workshop proceedings published in the ACM Digital Library and indexed in DBLP and Scopus.

Dates

  • Abstract submission deadline: July 13, 2022
  • Paper submission deadline: July 20, 2022 July 29, 2022 (Extended)
  • Notification of acceptance: August 19, 2022
  • Camera-ready deadline: August 26, 2022 September 6, 2022 (Extended)
