Subject: Question about the BusinessCard object
The business card (as in a piece of card printed with contact details)
is generally a mass produced object, handed out to whoever wants one
with no tailoring to the receiver. It is entirely one-sided, i.e. it
only contains the details of one business/person/organization. Other
sources of similar information would be the headed note paper and
trade or postal directories.
In order to start a UBL conversation it is necessary for the initiating
party to obtain the Party details of the receiving party, but there seems
to be no high level object that can be send just describing one Party.
These might be printed as QR codes on real business cards or headed
notepaper, or made available for download on a web site.
Once you have the partner Party details then the DigitalCapabilities
and DigitalAgreement conversation can happen, and these can also be
used to update Party information should the need arise.
So my question is why the BusinessCard has a mandatory ReceiverParty
in it, and why it does not have a DigitalCollaboration object? I
am here looking for a rational or definition objectives. It was
presumably added for a good reason/purpose, is that documented anywhere?
The UBL 2.2 Draft says:-
184.108.40.206 Business Card
The Business Card allows a standardized way of presenting digital trading
capability information in a form that can be published or exchanged with
The data structures have been derived from the work of ebXML CPPP, OpenPEPPOL
and other directory services initiatives.
It seems to me that is fails on two counts given this definition, firstly
the lack of DigitalCollaboration object which would enable the presentation
of digital trading capabilities, and secondly that it can not be published
to the world, it can only be exchanged with a trading partner, which should
not be necessary as if they are already UBL trading partners both sides must
already have the Party details for the other and the BusinessCard object
makes no provision for update, DigitalCapabilities/DigitalAgreement does.
Or to put it another way, what is the high level object that is
used by a Party to broadcast connection information so that others
may request communications with it? I am rather hoping that this
is not a piece of paper!
