This paper motivates, describes, demonstrates in use, and evaluates the Open Models Laboratory (OMiLAB)—an open digital ecosystem designed to help one conceptualize operationalize conceptual modeling methods. The OMiLAB ecosystem, which a generalized understanding of "model value" targets research education stakeholders who fulfill various roles method's lifecycle. While we have many reports on novel methods tools for domains, lack knowledge conceptualizing such via full-fledged dedicated...
The notion of "modeling method requirements" refers to a category typically neglected by RE taxonomies and frameworks - i.e., those requirements that motivate the realization (conceptual) modeling methods tools. They can be considered domain-specific, in sense all provide knowledge schema for some selected application domain (narrow or broad). Besides this inherent domain-specific nature, we are investigating how characteristics inform perspective, turn support engineering such artifacts....
The core process a modeling method engineer needs to accomplish starts with the acquisition of domain knowledge and requirements, ends deployment usable tool. In between, key intermediate deliverable this is specification which, ideally, should be platform independent. On one hand, it takes input from structured understanding application scenarios; on other provides sufficiently support implementation tool for activities. It quite common that such methods are domain-specific, in sense they...
Graph Database Management Systems brought data model abstractions closer to how humans are used handle knowledge - i.e., driven by inferences across complex relationship networks rather than encapsulating tuples under rigid schemata. Another discipline that commonly employs graph-like structures is diagrammatic Conceptual Modeling, where intuitive, graphical means of explicating systematically studied and formalized. Considering the common ground graph databases, paper proposes an...
The goal of this paper is to bridge the paradigms Linked Data and Conceptual Modeling, which have been developed from quite distinct concerns, although certain opportunities may stimulate evolution Web towards a new type knowledge space driven by diagrammatic models. To end, work at hand investigates structural patterns in multitude modeling languages accumulated over time within Open Model Initiative Laboratory defines for each pattern transformation rules that produce graph-based model...
The digital transformation of cities towards Smart Cities proposes many opportunities, e.g., related to services, security, waste and energy management, infrastructure management. These opportunities come with manifold innovation challenges, not only from a technological perspective but also for public authorities citizens. paper at hand introduces conceptual modeling as means handling the complexity City planning, operation. This presents multiple scenarios, indicating possibilities...
Data Flow Diagrams (DFD) have proven effective in designing and analyzing the flow of data enterprise systems. They serve as indispensable tools for enterprises that are undergoing transition to cloud services. DFDs aid understanding current processes, identifying interfaces integration points require security measures. This paper reports a Design Science project mitigate cyber threats at design phase system perform auditing an existing through knowledge graphs. The proposal leverages...
This article frames Conceptual Modeling education as a design problem, in the sense of Design Science research framework, motivated by student preconceptions and oversimplifications causing gap between how discipline is perceived at bachelor level holistic understanding model value that required for work. The treatment to this problem must comprise teaching approaches artifacts capable positioning standalone having proposition any application domain, rather than technique subordinated other...
Abstract. The hype of Large Language Models manifests in disruptions, expectations or concerns scientific communities that have focused for a long time on design-oriented research. current experiences with and associated products (e.g. ChatGPT) lead to diverse positions regarding the foreseeable evolution such from point view scholars who been working designed abstractions most their careers - typically relying deterministic design decisions ensure systems automation reliability. Such are...
