A disaster management metamodel (DMM) validated
In this paper, we present the development and validation of a Disaster Management Metamodel, a language that we develop specific for describing disaster management domain, as a foundational component to create a decision support system to unify, facilitate and expedite access to disaster management expertise. The metamodel which consists of four views based on disaster management phases including Mitigation, Preparedness, Response and Recoveryphase classes is developed by using seven (7) steps of metamodel creation process. To check the expressiveness and the completeness aspect of the metamodel, we validate this representational metamodel by analysing a validation over ten well-known disaster management metamodels which are chosen based on a Model Importance Factor criteria. The paper presents the synthesis process, the resulting metamodel and its validation.
