CPS, merging physical processes with computational technologies, offers significant potential for efficiency and innovation. The framework addresses the gap between the cyber and physical worlds within CPS, facilitating seamless data exchange and informed decision-making. Key topics include the design methodology, implementation steps, and the role of Semantic Web technologies like RDF, RDFS, and OWL. The framework's impact on communication, interoperability, and decisionmaking in CPS is discussed, with suggestions for future refinement and application.enThesis
