A case study has been published describing the e-invoicing infrastructure used for public e-procurement in Denmark. The current system uses ebXML Messaging to transport OIOXML UBL documents.
Transport of the eInvoices is based on an ebMS (ebXML Message Service) enveloping mechanism built on SOAP (ISO 15000-2). This means that the addressing information, mainly the EAN number, is part of the ebMS header.
ISO TC 68 is the technical committee of the International Standards Organisations dedicated to financial services. One of the major current activities is the ISO 20022 standard, also known as UNIFI. Transactions in the financial services industry are more complex than in other industries, as even simple transactions involve a large number of actors (debtor, creditor, their banks, clearing houses) and complex message flows.
The ebXML Business Process specification is designed to support complex choreographies and collaborations involving multiple business partners.
This presentation by Monica Martin of Sun Microystems, co-chair of the OASIS ebXML Business Process Technical Committee, explores interoperability and the role of ebBP within the eBusiness domain.
It is becoming critical for broad adoption among all partners – large or small - of a supply-chain, to handle differences in message flow capacity, intermittent connectivity, lack of static IP addresses or firewall restrictions.
