Subject: EU Directive towards giving EU public procurement a new Standard for e-invoices
Hi again UBL-Dev, Related to last comments, if anyone is looking at the new Directive for the EU for e-invoices, text approved by The EU Parliament here [http://www.europarl.europa.eu/sides/getDoc.do?type=TA&language=EN&reference=P7-TA-2014-0198] I get the impression UBL 1.0 Invoice might just fit but not sure about UBL 2.x Invoice because of several entities having a possible affect on invoice total calculations, etc, which are outside of what EU want to call 'core'. Anyone know what I mean? When UBL TC was working on UBL 1.0 Invoice I had some influence and I was being charged by my public sector colleagues with keeping it possible to have a core in the invoice such that other entities outside the core could feasibly be ignored. As such we didn't have much (if anything) outside the core which would affect core calculations (taking a typical view of what such a core would be from experience handling paper invoices). In UBL 2 there was a lot added and I was not so much involved but I didn't know whether the 'core' idea was getting any traction anyway, so maybe the 'core' idea with ability to ignore non-core entities and still have an invoice which is acceptable got broken. Now the EU seems to me to want to standardise this type of 'core' architecture and maybe UBL 2.x doesn't fit. I think it's a 'core' idea like the above - it mentions in arcticle 6 "The core elements of an electronic invoice are, inter alia:..." and that 'inter alia', together with other documentation I've seen about it, suggests the idea that the invoice can have other elements present besides the core but the invoice is accepted because the core is present and adheres to the Standard semantics. That last part is where things might go wrong - the semantics might ignore anything except the core when it comes to the calculations of totals, etc. This gives, I think, UBL 1.0 Invoice the advantage over UBL 2.x Invoice in that it has much less that might fall outside the core but might affect calculations. Does that makes sense? ---- Stephen D Green
