Interactive electronic technical manual object model (IETMOM)

An interactive electronic technical manual (IETM) is a digital package of information that is required for the diagnosis and maintenance of complex weapon systems and both military and commercial equipment. The lack of interoperability within and among IETM systems has become a major challenge to the US DoD IETM community. The initial phase of user-level interoperability support has been undertaken by the development of a Web-based Joint IETM Architecture (JIA). Within this architecture, there is a need to develop a standardized Web-enabled alternative to the IETM database specification. Object-oriented modeling provides the conceptual foundation for assembling the Web-enabled alternative out of Web components using Web technologies such as Java and XML. In this paper, we discuss a UML-based object model to manage the large and complex IETM database specification. We also define a UML extension to capture the semantics of the IETM database architecture
