The eXtensible Markup Language (XML) is a document markup language for the creation of hierarchical information structures. The document designer specifies (in a DTD) requirements on the document's content and provides choices for attributes of the contents. XML is supported by most major commercial software developers world-wide. A rich array of tools are already available to process and display XML documents.
The Astronomical Data Center (ADC, http://adc.gsfc.nasa.gov) is involved in a research project to define an XML format for the metadata of an astronomical repository and for large data tables. In the process, an XML tool box is being developed for importation, enhancement, and distribution of tabled data and their metadata documents. There is now a working draft Document Type Definition (DTD, at http://tarantella.gsfc.nasa.gov/xml/dataset.dtd) which specifies the required elements of content and their attributes.
The ADC is actively creating designs for the flow of data through automated pipelines from authors and journal presses into the ADC's XML archive, as well as data retrieval through the web via the eXtensible Query Language (XQL) (see accompanying poster by B. Holmes).
