Space systems are typical large complex systems. Knowledge sharing among stakeholders becomes crucial for a sound and efficient development or operation of a space system, as the scale and complexity of such a system grow. There are many activities involved in assuring safety orreliability of a system, and many software tools have been developed to support each of specific activities. However, such tools do not support coordination among different tasks, especially at the knowledge level.This report presents a framework for capturing fault knowledge based on ontology engineering.The purpose of the framework is to facilitate externalization of fault knowledge, which is to be shared among human or software tools. Two tools for supporting construction of ontology-basedmodels which have been built are described. We also explain the application framework for building ontology-based software we adopted in developing those tools, and address the problem of accommodating the changes of ontology in ontology-based software by ontology mapping.
