Roberto,      

      
      

      
Thank you for your reply.  But I still do not understand.        

      
      

      
You say that the Business Card is intended as the electronic version of the      

      
paper equivalent, but then later you say that the recipient is required.      

      
You have a basic bootstrap problem here.  How do you get the receipient      

      
Party data?  Surely if the Business Card followed its paper equivalent      

      
then it would be destination agnostic.  And removing the recipient in no      

      
way stops it being forwarded.  You already have the separation between the      

      
sender and the business parties.    

      
    I understand your point, but the UBL-BusinessCard is not only a    card, it is primarly a message.

      
 

      
If it primarily a message, what the receiver do with it, and how would they reply?

      

    I think any UBL business document has a sender and a recipient, as    we are supporting business processes and collaborations so the    minimum number of parties involved is 2, do you agree ?

      
 

      
Why exclude the concept (as defined in its purpose description) of a broadcast object which can be sent to anyone without tailoring.  Such broadcast objects have a real use in such cases as starting the whole communications system.

    
    This is an additional requirement, but it looks it is more a
    requirement for an envelope or a distribution list to be handled by
    a provider. I think it is not a good idea to bind a set of
    recipients in a broadcast object, if this is what you intend.

    If we remove the 1..1 cardinality from the RecipientParty then the
    UBL-BusinessCard will be suitable for sharing it on a website or
    stored into an XML database for direct use.

    

    I may be wrong, but the broadcast aspect seems to be outside of
    scope for UBL, we can describe it at process level, but we need a
    use case for that.

    

    
      
    
    Most UBL documents are requiring both the sender and the recipient    parties, not all... but this is when we must give more freedom to    implementers.
    If you think that we must give such freedom I could agree, but this    means you think implementers may use the UBL-BusinessCard for    storage and not *only* for exchanging its information.

      
 

      
I see to need to include the recipient data in a broadcast object.

    
    

    
      

    I like this idea, after all XML databases are a reality, so it could    be that modern portals, yellow pages or business directories will    adopt the UBL-BusinessCard as a direct storage unit on the file    system or in a database blob.
    
    The recipient will be added on the last stage before sending it to    other parties.

      
 

      
How can the recipient be added when downloading it from a web site or from a QR code printed in a physical directory?  Or are you saying that I would have to fill in all my Party data in order to download the BusinessCard froma web site?  

    
    No, what I mean is that the UBL-BusinessCard can be used in a early
    stage as a storage unit for holding Party Information without
    indicating a recipient... later when you need to send it to anyone
    you will use a software able to edit such UBL document for adding
    the recipient.

    

    
      
This would an error prone process and rather defeats one of the driving features of UBL which is to eliminate duplicate typing.  I could not upload my pre-populated BusinessCard because it would not have a receipient Party in it.

    
    I think in my previous comments I accepted the idea to remove the
    1..1 cardinality for the recipient so that this business card will
    be used into different use case:

    - holding party information in a database (without a recipient)

    - sharing the party information on a website (without a recipient)

    - sending the party information as a message to another party (with
    the recipient of course).

    
      
    

      
      

      
You say "The recipient is mandatory ... because it is intended to be      

      
exchanged".  Yes quite often when you hand out business cards you get      

      
one back, but not always and the cards that are handed over are not marked      

      
for the recipient in any way.  The same goes for directories, they do not      

      
contain (or at least they do not have to contain) the recipient's       

      
Party data.      

      
      

      
When it comes to the digital collaboration object, these are absolutely       

      
fundamental to UBL and saying that the DigitalCapabilities object is the way        

      
to exchange this misses the point.  How can you send the DigitalCapabilities      

      
object to someone when you do not know where to send it?  It is a recursive      

      
unresolvable problem.    

      
    First of all I fix the name that is singular    "UBL-DigitalCapability", my mistake on the previous mail.
    
    

      
      

      
      

      
There has to be a way to start the communications, and traditionally that is      

      
what the business card or directory entry do and they are broadcast objects      

      
not directed to a particular recipient.      

      
      

      
To my eyes the text in section 2.3.8.2 is exactly correct, and it is the      

      
implementation of the BusinessCard object that is wrong.  And it as you      

      
suggest the second paragraph of section 2.3.8.2 should not be in the      

      
description of the BusinessCard but rather in the DigitalCapabilities      

      
section, why is it there?    

      
    BusinessCard should not be mixed with the DigitalCollaboration, the    second one is strictly for configuring EDI systems.

      
 

      
Perhaps not, but it is needed as part of the process of introducing two businesses to each other, at at least it could be used to good effect if it were a broadcast object.
    
    I agree the folowing is wrong and needs to be revised asap:
    
    

      
      

      
        

      
          

      
>2.3.8.2 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 trading partners.    

      
>The data structures have been derived from the work      of ebXML CPPP, OpenPEPPOL and other directory services      initiatives.

      
    It should be:
    
    "The Business Card allows a standardized way of presenting general    trading capability information as well as main company's    communication channels and presentations such as flyers and    brochures."
    ____
    The DigitalAgreement part is ok but there is a missing paragraph for    the DigitalCapability document.
    Please review this:
          

      
        

      
2.3.8.3 Digital Capability              

      
The Digital Capability allows a standardized way of      presenting digital trading capability information in a form that      can be published or exchanged with trading partners.  The digital      capabilities of business partners are the source for building a      Digital Agreement.
        

      
      

      
2.3.8.4 Digital Agreement  (...I JUST RENUMBERED THIS...)
              

      
Bi-lateral and multi-lateral trading partner agreements      can make use of the standardized Digital Agreement document used      to support business parties agreeing on a set of digital      processes, terms and conditions.   

      
 

      
      

      
      

      
If the BusinessCard object is not designed to start the communications,      

      
then what is and why is it not part of UBL?  If the BusinessCard object      

      
is not there as a broadcast object to start the process, what is its      

      
purpose?  From your description the process starts at the DigitalCapabilities      

      
object, the BusinessCard is useless and thus should be removed from the      

      
standard.    

      
    It is true that in the specification there is a missing graph    overview for the BusinessCard document, while the graph for the    Digital Agreement and Digital Capability is correct.
    
    The BusinessCard is more generic and related to the common practice    of exchanging business information in different domains:
    - Marketing and communication (Web sites, social channels, ...)
    - Financial Information (e.g. When I want communicate my new Banking    account to my partners)
    - General information (Address, Tax IDs, so on...)
    - Trading capabilities (What the company do in textual form)
    
    Of course it is intended also to introduce a company to another, but    it is not specific for digital processes.
    
    The DigitalCapability is specific for service providers, EDI    partners, and of course for building digital agreements.
    The communication can be started with a plain BusinessCard or    directly using a DigitalCapability if the purpose is to start a    digital collaboration.

      
 

      
Not at all sure this makes sense.  The whole point of UBL is to make as many parts of business interaction digital, it is the definition of how that digital interaction should occur and how the dataflows should be structured.  Why is UBL defining a non-digital object?  The useful thing to do is to use the Business Card concept and extend it into the digital world and the concept is to broadcast information.  

    
    David, I never asserted that the UBL-Businesscard is not
    contributing on the digital world... in fact I provided you with
    several examples... such as the need to update a business party with
    my new bank coordinated or my new Tax ID.

    The upper usage is very important into real business.  We do not
    send business cards only for describing Digital Agreements.

    The DigitalCapability document is strictly associated to the
    DigitalAgreement and it represents a precious instrument for service
    providers.

    The BusinessCard is more generic. You can think the BusinessCard is
    partly overlapping with the DigitalCapability, but they can be used
    into different processes.

    We can start using a BusinessCard and never exchange a single
    digitalcapability and DigitalAgreement, or we can exchange all of
    them.

Hello David,      sorry for waiting so long before providing an answer, I was unable      to work fro a while...      please find below my answers:            Il 29/09/2017 16:26, David Goodenough ha scritto:              

      
                        

      
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.          

      
    Correct, this reason the UBL BusinessCard is not intended for    instructing EDI / B2B systems.    Inside it you can provide Business capabilities in general but not    Digital capabilities.    The Business Card is intended as a standard electronic version of    the paper one, that can be also used for exchanging data between    business directories or simple yellow pages systems, accounting or    banking systems.           

      
            

      
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.          

      
    The UBL DigitalCapabilities are the document you need, this is    exactly designed to exchange digital capabilities such as plain old    EDI or new XML capabilities.          

      
            

      
            

      
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 Recipient is mandatory because of course the UBL BusinessCard is    intended to be exchanged (e.g. to a provider, bank, partner, ...)    In case the Recipient acts on behalf of another party you can use    the BusinessParty information accordingly.          

      
            

      
The UBL 2.2 Draft says:-            

      
            

      
>>>            

      
2.3.8.2 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             

      
trading partners.           

      
    Yes, this seems to be uncorrect, I would remove the term "digital"    in the beginning.    The only way to describe digital trading capabilities within the UBL    BusinessCard is by using textual description.          

      
            

      
            

      
The data structures have been derived from the work of ebXML CPPP, OpenPEPPOL             

      
and other directory services initiatives.            

      
>>>          

      
    Correct, but this should be correlated to the UBL    DigitalCapabilities document.          

      
            

      
            

      
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.          

      
    Digital trading capabilities are described in terms of processes,    collaborations and transactions.    You must traverse the DigitalProcess information aggregate.          

      
            

      
            

      
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!
