From an IOC/IODE perspective, the requirement was to design a framework for an XML structure that data centres can use. It is thought that a mutually acceptable structure will solve many problems. A series of short presentations were given to illustrate XML developments in the various organizations represented. These presentations, predominantly served to initiate a series of discussions. The main requirements for an XML based exchange system involved the development of a document type definition (DTD) and standardised syntax for common content (code tables).
