Abstract:
XML syntax is just the foundation for data interoperability. The next step is semantic transparency. Some groups are working to address this by defining entire document formats to be adopted wholesale, while other groups are working on ways to express common terminology and concepts at a more granular level. In this installment, Uche Ogbuji looks at XML Topic Maps Published Subjects and Universal Data Element Framework (UDEF), two ideas that take the granular approach by seeking to provide anchors in the semantic stream.
