Historical place databases can be an invaluable tool for capturing the rich meaning of past places. However, this richness presents obstacles to success: the daunting need to simultaneously represent complex information such as temporal change, uncertainty, relationships, and thorough sourcing has been an obstacle to historical GIS in the past. The Qualified Assertion Model developed in this paper can represent a variety of historical complexities using a single, simple, flexible data model based on a) documenting assertions of the past world rather than claiming to know the exact truth, and b) qualifying the scope, provenance, quality, and syntactics of those assertions. This model was successfully implemented in a production-strength historical gazetteer of religious congregations, demonstrating its effectiveness and some challenges.

Abstract The paper deals with the process of shaping the operational effectiveness of military aircraft under some specific circumstances, i.e. while flying on missions. The term ‘effectiveness’ has been assumed to mean the probability of accomplishing an air mission by one of the aeronautical system’s components, i.e. the aircraft together with its pilot. There is a chance to improve the effectiveness, or make it worse, in subsequent flights, depending on how the maintenance support function. The correct operation and maintenance of the system’s components should provide that the following condition is satisfied: * Pk ≥ P , where Pk - effectiveness in the k-th flight, and P* - the lower demanded limit of effectiveness. The Authors drew their inspiration for this paper from publication [2].
