I have to agree with Kurt. Subject matter experts may well be experts at the subject, but making 'expert' data models work is not always a good idea. I'd probably go further, though. Frankly, when building data models, I'd much rather have a mix of skill levels and perspectives involved. Different participants have different views on the data, but there's often more than just views on the same data model - there are often different internalized data models. Combining those different models with data structures requires more than just careful data design. I'd argue it involves programming, transformations at minimum, that ensure that the data presented meets local expectations. That's never easy, but I don't think it's avoidable. It's been a long time since I've been involved with this in an XML context (though I'm starting to work with it in a database context again), so I'm a bit cautious about saying this. Nonetheless, it seems so obviously true to me that I might as well. Thanks, Simon St.Laurent XML retiree
