1. Make a more powerful interface for the portal- more sophisticated search / browse possibilities- better possibilities to handle results

2. Handle more complex datastructures, over time, across space, link micro – macro

3. Handle problems of double storage. Identify, version, compare, put in context

4. Data dynamics, more than one value in a table cellVersioning, updating

5. Single Sign On, need to pass information and access more than one server, logging

So, what about DDI ?

DDI: The ultimate list of documentation elements – another resourceStorage and transport between applicationsThe guarantee that we talk together

Elements are identified, have an authorityand may be versioned

XML: Build from the basic line upwards
