eLife Coupler allows applications of two organizations to properly process the documents exchanged between them in ebXML. These documents may be purchase orders, invoices, customs declarations or insurance contracts, to name just a few examples. An example for a sector-specific standard ebXML format is papiNet® (see www.papiNET.org )

While interoperability requires exact maintenance of ebXML standard requirements between two Message Services, a high degree of flexibility is needed to connect the Message Service to the application software in the back-end of an organization. Here, the Coupler interface simplicity plays an important role in implementing this technology..
