Hopefully XML would make that number *smaller* :-) --- No minor nit indeed -- that is tax $$ out of your and my pockets. Having studied this problem in some depth for several years I've become convinced that "semantic web" _like_ technologies are the only viable solution -- essentially the data needs to be majorly cleaned up to allow automated processing. Converting the data to XML is just the first step, the next step is that the data needs to be better classified which is where "semantic web" technologies i.e. ontologies fit into the picture. My view of "ontologies" is that they are a way to take what looks like free wheeling data and give it a _very precise_ (and hence machine processable) definition. Since the medical terminology size easily exceedes 200,000 terms (by SNOMED alone, and there are a number of other important healthcare terminologies) other ways of defining controlled terminologies aren't appropriate to the task -- can you imagine what a complex XML Schema that defined >200,000 elements and types would look like? In my view, XML is indeed part of the solution, but doesn't itself answer the question of what we do with all that data once it is in XML. Jonathan
