Review of Atlantic call minutes of 2011.01.05
GKH: Andrea reports that Security SC has approved the latest
changes.  JB has now been given all the expected text.  SGTG
will put revised schemas through our acceptance process as
soon as eDoCreator has been updated with the changes for
PRD2 (still undergoing review in PSC and TSC).  All text
deliverables from GKH are now complete.  Question: will the
Security SC document itself be part of the 2.1 package?
JB: That is currently the plan of record, but will consider
this again for next week's call.  UBL 2.1 STATUS
TM: PSC meets today to finalize three of the five remaining
issues.  TSC will probably meet Friday.  MESSAGE ENVELOPE
High points of the discussion:
- A primary use case is the envelope for tender submissions.
- AH reports that the OASIS Energy Market Information Exchange
(eMIX)

TC has identified a similar need for a document
containing a bundle of documents (e.g., associated warrants
or energy certificates), each with its own metadata,
together with a requirement to identify one of the documents
in the bundle as primary.
- Sweden has confirmed the BII finding that UN/CEFACT SBDH 1.3
will not, in fact, support a bundle of document instances in
a single envelope in a way that meets BII business
requirements.
- AH reports that Stephen Green independently attempted an
implementation of SBDH and had to abandon it because of this
limitation.  Stephen has identified use cases with multiple
documents of different types in the same bundle or even the
inclusion of non-UBL documents, e.g., the inclusion of an
XBRL-GL ledger instance.
- It appears that GS1 has had to make its own adaptations to
the SBDH, presumably for the same reason.
- It is our independent finding that the SBDH as currently
specified (xsd:any without maxoccurs unbounded) cannot
support multiple document roots as siblings if metadata is
associated with each document.  This problem could be solved
by setting maxoccurs to unbounded, but apparently there are
other business requirements that this solution would not
address; we are seeking further clarification from BII on
this point.
ACTION: TM to provide a snapshot of the BII model (with
the understanding that this is a work in progress).  TC CONCALL SCHEDULE
