Panel Questions
 Is current technology sufficiently expressive for
  pure modeling or do we miss something?
     Difficult to determine because most approaches are
     proprietary and closely-held intellectual property.
     Used for competitive advantage.
Panel Questions (continued)
 What are runtime challenges like throughput and
  performance in modeling approach?
    Modeling tools should allow us to express quality-of-
    service issues such as scalability, response time,
    availability, etc. (See ECEB Home Page).
 Why do many projects use programming rather
  then modeling?
    Time constraints, vendor-specific tool kits, lack of
    high-level modeling tools.!
Panel Questions [continued]
   Is it possible to follow a 100% modeling approach for
    semantic B2B integration?
       Why bother with modeling at all?
   Do we have sufficient understanding of B2B
    requirements?
       Of course we do: Web Services to the rescue!
   Web Services allow companies to package their
    Intellectual Property and make it available as a
    service via the Internet.
