Conclusion

XMI and new industry-specific schema, such as JDF, have bridged the gap between XML methodologies and Object-Orient Methodologies and provide examples of the symbiotic relationship between XML and Object-oriented methodologies that is developing. Markup languages and object-oriented programming, analysis, and design methodologies are merging into a single logical super-system that one day may become universal in their application. Although XMI, and even XML and UML, are new technologies, they complement each other well and provide for a link between programming languages and users. Although both technologies must evolve, an analysis of their historic development reveal that they are merging technologies, that someday may be considered one symbiotic logical system.
