Hi David A typical example here would be the current account systems of most UK clearing banks whose 'current balance' is actually the amount in the account after yesterday's transactions have been applied and don't know about anything that has already happened today, or what transactions were queued up to be applied today. These systems may also assume that they will only be interrogated between 8am and 8pm, the currency is assumed, not explicit, the applications have no real service levels for response times, and they can show confidential information that is expected to be filtered and interpreted by an employee. I think that my fear is that there'll be a different set of assumptions for each company's web services and that it won't be possible to capture these within the discovery protocols so that discovery will not be automatic and the interoperability challenges will be of a similar size to those of implementing EDI, but with an even larger legal bickering process over who's responsible for errors. tc ----- Original Message ----- From: "David Booth" <dbooth@w3.org> To: "Tim Coote" <tim@coote.org>; <www-ws-arch@w3.org> Sent: Wednesday, March 20, 2002 4:21 PM Subject: Re: architecture question > Tim, > > At 12:50 PM 3/20/2002 +0000, Tim Coote wrote: > >The biggest challenges tend to come from very old assumptions (~20 years > >old) in line of business applications. > > Can you elucidate?
