| Abstract: |
While XML-based Web Service architectures are successfully turning the Web into an infrastructure for cooperating applications, not all problems with respect to interoperability problems have
yet been solved. XML-based data exchange has the ability to carry the full Unicode character repertoire, which is approaching 100'000 characters. Many legacy application are being
Web-Service-enabled rather than being re-built from scratch, and therefore still have the same limitations. A frequently seen limitation is the inability to handle the full Unicode character
repertoire. We describe an architectural approach and a schema language to address this issue. The architectural approach proposes to establish validation as basic Web Service functionality,
which should be built into a Web Services architecture rather than applications. Based on this vision of modular an infrastructure-based validation, we propose a schema language for character
repertoire validation. Lessons learned from the first implementation and possible improvements of the schema language conclude the paper. |
