Subject: RE: [ubl-psc] RE: [ubl] Defining Geograpic areas in UBL - How?

Thanks once again for helping us understand just how to address new
requirements in UBL.  The circular area was just my alternate guess of a
possible new requirement. It may be valid in the future but I don't think
that it is required for Freightwise..

Forgive my oversight, Audun ... you are of course correct and in my 
haste I overlooked the cardinality of cac:LocationCoordinate as well 
as the other mistakes that I made.

But knowing this would address your issue gives us a direction for 
proposing UBL 2.1 modifications.

Again this morning I am in a rush (I am traveling and teaching this 
week and am about to head to the airport), but I want to keep the 
discussion going.  Perhaps all we need to do for UBL 2.1 to describe 
a polygonal area is change the cardinality of 
cac:Address/cac:LocationCoordinate to "0..n".

At first glance I thought the name would be misleading, but then I 
recalled that in UBL we never use the plural in a name, we only use 
the cardinality to indicate how often the item is used.  Thus, I 
think changing the cardinality to be a multiple does not prevent us 
from re-using the currently named construct.

I'm less clear about adding the ability to specify a point and 
radius, regarding my initial thought of whether we can augment 
cac:LocationCoordinate to satisfy this need.  Having slept on it I 
think not.  I now wonder if this requirement should be a new ASBIE 
cac:Address/cac:LocationDimension with a cardinality of "0..n" where 
the associated object class of cac:LocationDimension is 
cac:Dimension.  Thus, the cac:LocationCoordinate can be used to 
pinpoint the centre and the new cac:LocationDimension can be used to 
describe the radius.  But we keep the new cardinality on 
cac:LocationCoordinate to satisfy the need to describe polygonal areas.

So, then, would the following summarize suitable changes to propose 
to UBL TSC for consideration in UBL 2.1?

  (1) - change ASBIE cac:Address/cac:LocationCoordinate cardinality to
  (2) - add ASBIE cac:Address/cac:LocationDimension associated to
        and with a cardinality of "0..n"

I hope this is considered helpful ... I have found this a useful 
exercise in my own understanding of how to add to UBL to meet new

p.s. thank you for your patience with my mistakes
