This paper deals with the comparison and management of (heterogeneous) temporal datings in pre- and protohistory. It will present a first draft of a conceptual model for the description of the most common types of scales used in this context. The aim is to enable a system to compare objects according to their dating, regardless of the used method and scale. Thus temporally relevant objects can be selected by a query and do not need to be selected manually by an expert. Especially for larger data sets, automated computations, integrity checks, temporal reasoning or pattern mining this is beneficial.
