That's not what I mean -- creating a data model is tractable, but a
data model is of questionable value if it's not based on a fairly
accurate business model, use cases, etc. I don't think that any of us
can reasonably draw up a reliable business model that will cover the
Web for the next five years, and even the use cases will be pretty
shakey. Without good models, bottom-up is our best bet.
All the best,
