The technical terms for this form of phobia are "modeling & simulation
federation" and "service-oriented architecture:" We agree on a common
information exchange model, such as XML or OMT, but everything we really
capture is the structure. Two models, services, etc. can implement the
meaning behind these pieces of information completely differently ...
that's why we are pressing the issue of formal models for
conceptualizations.
Enjoy the weekend
