RE: Motivations for namespaces (sorry)
We see loads of conflicts if not outright collisions. For example, in one court, a judge prescribes "remedies"; in another, the judge prescribes "dispositions". Some agencies process events; others process incidents. God bless NIBRS/UCR. Without a data standard, some businesses aren't worth getting into, but this is classic data dictionary work. In the interagency apps, trying to sort out same name for different things, different names for same thing is a major task. We solve them with code transforms (map in the functions), XSLT (map in the transfer), system lookups (code tables) but so far, never with XML namespaces. I think an industry has to be fairly saturated with XML apps before that happens and as David said, there is less of this in the wild than some might believe. I think namespaces are useful at the junction of a 'blind' exchange. Those may be rare in some domains until the agencies really open up, but most of the time, messaging is a baroque dance: detailed and well-planned. Collisions are a bigger headache for the proposal staff than the programmers. Maybe messaging systems need namespaces less than document systems and even then, how often does one see an app language wrapping another app language? In theory, yes, but with the exception of how MS does this in their browser, how often? len -----Original Message----- From: Joseph Mayer [mailto:jmayer@k...] I'm certainly not up to speed enough on any of the debates to say one method is better than another, as I'm just getting seriously involved in using XML around the business, but I do know that there's certainly a possibility of a real collision happening here. There are a number of other fields with the same kind of issues in our ERP system, and I can imagine that other systems would have similar "inbound vs. outbound" problems with similar names.
