Subject: Re: [unitsml] UNITSML discussion: WSDL conversion services
Bob and Peter This message is intended to be part of the "asynchronous" part of the August UnitsML discussion. I am in agreement that keeping things simple this first time around is the best way. This is Stuart Chalk and I approve this email ;) On Aug 27, 2008, at 2:22 PM, Bob Dragoset wrote: > All & Stuart, > > This message is intended to be part of the "asynchronous" part of > the August UnitsML discussion. > > I agree with you Peter, for two primary reasons: > > 1) Each WSDL service is required to include information regarding > how to access the service; e.g., required and optional input > parameters, format for both input and output parameters, etc. I'm > not an expert in WSDL services, but I don't see the advantage of > allowing the user to include the instructional information (provided > by the WSDL service) in the UnitsML portion of an instance document. > > 2) As far as I'm aware, we have not included numeric values in the > UnitsML portion of an instance document; the numeric values of a > quantity would be handled elsewhere in the instance document.
