If its possible to agree on Predicates and Schema for
XML::Edifact and to code it, it should be possible to inherit
from this schema to map a lean XML/EDI to XML::Edifact and therefor
to UN/EDIFACT.
Think about following vapor ware message:
        <newbooks:orders>
           <party
                qualifier="supplier"
                id="0123456789"
                name="Missing Link"
                />
           <party
                qualifier="customer"
                id="9876543210"
                name="Michael Koehne"
                />
           <reference
                date="Wed Jun 23 18:47:27  1999"
                number="234"
                />
           <item
                number="1"
                isbn="0-12-345678-9"
                author="anon"
                title="the book never written"
                publisher="nowhere press"
                />
        </newbooks:bookorder>
Compared to the lengthly messages XML::Edifact produces, this lean format may be better suited for transfer on the Internet. If newbooks now provides a RDF for his lean XML/EDI mapping between newbooks:orders and edifact:orders can be done.
