An open standard for Web-based condition-based maintenance systems

An effort is underway to develop an open system architecture for condition-based maintenance (CBM). The architecture development has focused on the definition of a distributed software architecture. The general requirements for a CBM software architecture are defined and an outline of the developing architecture is given. This paper will discuss in detail a web-based architecture which uses Extensible Markup Language (XML) to define the syntax of messages between software components. The core of the architecture is a CBM domain data model which is defined using Unified Modeling Language (UML). A procedure for mapping from the UML data model to a general XML schema, as well as to a schema for system messages, is described
