Subject: RE: ebXML Representtion of Metadata
Message text written by "Duane Nickull" > Although I am not an XMI expert, the one persistant shortcoming that I keep hearing with XMI is that it cannot provide a "consistent" way to interchange metadata. Does anyone have an answer for this comment? Duane Nickull <<<<<<<<<<<<<<<<<< Add to this that XMI creates DTD's that look like they have been written by a machine. I.e. no self-respecting human would want these for a production environment. Now this is a critism - based on the fact that humans write DTD's that contain a whole level of intelligence and criteria that are NOT part of a UML model today - such as Oracle SQL optimization criteria, just as an example. OK - this was my point earlier - as machine intelligence increases and peoples understanding of what a good production quality DTD does and does not contain, then you can get XMI to mimic this behavoiur. We are not there yet! Am I about to 'spray paint the car' so the robot can copy me 100 times faster right now? I'm probably not ready to do that either! <g>. This is why I see that XMI, UML and related tools will improve, but not for another one year minimum, as we're all still learning. DW.
