An implementation-oriented model to represent uncertain temporal information in databases is proposed. Temporal information is presented to the user as anchored time intervals with optional beginning and end dates. The model accounts for both instants and intervals, and can be applied to uncertain dates by leaving days and months optional, or by using symbolic constraints that present additional time granularities. The model is defined using conventional relational database structures to support ease of deployment and integration to legacy systems with efficient query capabilities. The model is based on experiences with an existing museum database and highlights challenges related to temporal representation of cultural-historical data in practice. The model is compared with temporal representations used in other museum information systems and collections management standards. Possible opportunities to extend the model in the future research include defining a formal algebraic presentation or utilizing an explicit time ontology. ...
