Abstract:	XML—the Extensible Markup Language—is a developing standard in which the description of the data (the metadata) is included with the actual data in a single electronic document. This presentation focuses on the use of XML for accessing and understanding tabular data, particularly for handling the responses from queries to on-line catalog services. If such responses are encoded in XML using agreed upon tags and attributes, it is possible to both display the data in clearly formatted tables and use the data in other applications (such as generating graphical overlays of object positions on survey images). XML-encoded tables can also provide the basis for the next generation of data discovery and integration tools (Astrobrowse, ISAIA). The detailed definitions of XML tags and attributes, including examples and a working DTD, are described at http://vizier.u-strasbg.fr/doc/astrores.htx
