Re: [ubl-lcsc] UML class diagrams generated from draft 4

[Tim McGrath <tmcgrath@portcomm.com.au>]

it is quite impressive how close the orginal and the generated diagrams are!
 i must admit yours are more readible 
:-[ 

a few things stand out though:

associations: 
a. naming of assocations - these are important to show where the names of
ASBIEs come from.  
b. the cardinaility of associations applies to each end - a guess if you
assume the navigation path from the arrow direction (see comment below) then
i suppose on the 'target' cardinality is useful.
c.association or generalisation - i thought that the filled-in triangular
arrowhead denotes a generalization (it seems to sometimes be filled in and
sometimes empty).  but 'Address' is not a generalisation of 'Party'?? what
i thought we wanted to show was navigatable associations.. that is 'knowing
a Party we can find its Address'.  thats why i used the -> type arrowhead.
  have i got i wrong?

packaging:
 it is somewhat awkward but we need to make decisions what goes in which
package - for example having Address inside AllowanceCharge is not inituitive.
 the schemas themselves don't convey these packages - so i am not sure how
you could logically group things.
