I am unable to find any, can anybody give >me a pointer ? TIA ANSI and ISO are working on SQL/XML, which provides a standard mapping from tables to W3C XML Schema. Here's a good article on SQL/XML by Jim Melton and Andrew Eisenberg: http://www.acm.org/sigmod/record/issues/0206/standard.pdf I believe they have added an alternative mapping since this article was written. As for DTDs, many people want to represent the data types found in RDBMS when they map to XML, and DTDs don't provide support for data types. RELAX-NG combined with the W3C XML Schema data types would work great, but there's no industry consensus behind that kind of solution. So if you want a mapping that is industry standard, which database companies will actually be supporting, I think SQL/XML is what you want. Jonathan
