	abstract = {The field of software modeling has gained significant popularity in the last decades. By capturing the static aspects of the software requirements, model-driven engineering eases the development and maintenance of software. However, additional constraints, such as invariants on model elements, that the solution must conform to may be too complex to include in the structure of the model itself. External solutions are often used to describe static constraints on models, the most prevalent approach being the Object Constraint Language (OCL) and its formal variants. This paper proposes the Generalized Formal Model-Verifier (GFMV), which is a general approach for verifying static constraints on software models. GFMV employs different formal verification methods based on Kripke Structures. Kripke Structures are used to capture the static structure of the model, then the constraints are formalized using a first-order branching-time logic, the Computational Tree Logic (CTL). Finally, the NuSMV model checker is reused to verify whether the constraints formalized in CTL hold on the formal Kripke Structure. When compared to existing solutions, GFMV offers increased generality and formal proof that the constraints hold on the model. The expressive power and runtime-scalability of the approach are evaluated on a real-world example model and OCL invariants cited from literature. © The Author(s) 2024.},

	abstract = {Traditional two-level modeling approaches distin-guish between class- and object features. Using UML parlance, classes have attributes which require their instances to have object slots. Multi-Level Modeling unifies classes and objects to 'clabjects', and it has been suggested that attributes and slots can and should be unified to 'fields' in a similar way. The notion of deep instantiation for clabjects creates the possibility of 'deep fields', i.e., fields that expand on the roles of pure attributes or pure slots. In this paper, we discuss several variants of such a 'deep field' notion, pointing out the semantic differences and the various resulting trade-offs. We hope our observations will help clarify the range of options for supporting clabject fields in multi-level modeling and thus aid future MLM development. © 2023 IEEE.},

	abstract = {Modern software development has drastically changed the role of compilers with the introduction of responsive development tools. To accommodate this change, compilers have to go through an architectural transformation, diverging from the classic pipeline. A relatively new idea is called query-based compiler design, which took inspiration from build systems. It splits up the pipeline into smaller, individual operations, which - given some constraints - allows for some interesting optimizations. We argue that some programming language semantics introduce cyclic dependencies between certain compiler passes, which can naturally lead to rediscovering query-based compilers. In this paper, we present a framework that can be used to create compilers with a query-based architecture. Based on this framework, we introduce the Yoakke programming language, which we also use to explore our hypothesis regarding cyclic dependencies and rediscovering query-based compilers.},
