Strong agreement. But let's remember that you cannot have a theory
of content without a process model - something some luminaries
involved now in the semantic web/ont efforts realized a long time ago.

So much of what we want to know is abductive, and cannot be
discovered by writing everything down and running theorem provers
over the data. I think Walter is trying to remind us that processes
and process models must play a big part - on the other hand there's
no question that at the moment there are far too many conditional
blocks in systems code ('business logic' in the jargon) that would
be better off placed in declarative sentences for comsumption from
pattern matchers to reasoners.
