On Temporal Cardinality in the Context of the TOWL Language

The TOWL language is a temporal ontology language built on top of OWL-DL that enables descriptions involving time and temporal aspects such as change and state transitions. Extending OWL-DL into a temporal context does not only relate to providing the adequate expressiveness for such a goal, but also ensuring that static concepts preserve their meaning in a temporal environment. One such concept relates to cardinality. In this paper, we discuss temporal cardinality in the context of the TOWL language, and provide a possible approach towards representing temporal cardinality in this context.
