Re: [ubl-dev] Comments on UBL-NDR 2 Versioning

["Stephen Green" <stephen_green@bristol-city.gov.uk>]

The size factor seems to be exacerbated somewhat
by the number of attributes in many of the datatypes.
However I'd like to think it would be straightforward
to use the UBL 2 library and most of all the UBL 2 NDR
to craft quite 'small' schemas. Then if small is especially
beautiful in the eye of the implementers :-) one can
use the ASN.1. Maybe it might be a successful line of
approach to create a set of qualified datatypes first
with either fewer attributes or, if convenient, with
more default content used (as with the UBL codes).
This should reduce the size a lot with only discretionary
loss of functionality. In the process one might also
restrict the datatype content such as to restrict the
length of strings and numbers (much as ATG 2 seem to
have done with their qualified datatypes). So the
size and XSD complications don't come so much to bear
on use of UBL Library and NDR to create completely
new documents. Then one gets the benefits of the
versioning and extensibility of the schema design rules
along with UBL's pioneering application of the ISO
standards 15000 and 11179.

If I were implementing UBL today I'd want to allow
for all these options (though I'd not necessarily use 
all of them - see those documents posted at
http://www.systml.co.uk/xml/ ).

All the best

So what would you say is the current state of UBL pickup in Asia?

My impression is that UBL is getting bigger (and therefore more  
expensive) to implement every time I look at it. Version 2 seems to be  
a real humb-dinger.

Given that in Asia there is a preference for 'cheap' and 'quick'.. I'm  
wondering who is picking it up?

What accounting system integrations are there so far?

Just wondering...
