Re: [ubl-dev] Getting started with UBL-2.0

[David Pratt <fairwinds@eastlink.ca>]

Hi Roberto. Yes, I feel extremely encouraged and thankful for the 
responses. Many thanks again to all that have responded and offered such 
excellent advice. It is all very much appreciated. I definitely feel I 
am being set on the right course by the experts. That means quite a bit 
when you are just getting your feet wet.

I have quite bit to digest in the interim and right now am giving 
critical thought to my application to determine the changes that I will 
begin shortly. First, I will ensure that my data models will work and 
that I make use of the available BIE's and UBL document schemas. Second 
will be to determine the workflows necessary to trigger the creation or 
transmission of documents and also the handling of documents/messages to 
the system. Beyond this I can see the next step being the putting a skin 
on the documents so are nice to use from a human perspective. I'll be 
following the effort of the Human Interface Subcommittee in the interim. 
Hopefully I may contribute some effort here as help is needed but I will 
need to first increase my understanding in the interim.

I found the UBL Swinger very intuitive and it was this tool that really 
opened my eyes to visualize the potential of the BIE's and the common 
aggregate schema - so thank you for this work Roberto. I'll be looking 
forward to any update to this.

Regards,
David
