Ontologies play a critical role in structuring and sharing knowledge across diverse domains, particularly in quality management and business process modeling. Temporal concepts are essential to accurately represent the dynamic aspects of these processes. This paper extends the Descriptive Ontology for Linguistic and Cognitive Engineering (DOLCE) to integrate temporal dimensions into business process ontologies. Our approach includes the development of a dedicated time ontology, its alignment with BPMN (Business Process Model and Notation), an implementation of temporal properties using the Camunda Modeler tool, and a demonstration of its application in a clinical case study. By mapping temporal concepts such as intervals, deadlines, and delays to BPMN elements, we enable precise modeling of time-sensitive business processes.
