PSC REPORT
PLB: Still have about five open issues, which have all been
assigned to resolution groups that have not yet returned with
their findings.  Most are expected in a week or so.  The
biggest issue has to do with the question of a message
envelope.
TM: This question goes back to UBL 1.  The requirement is to
create a container document for other documents, i.e., a
structure that can be used to describe sender, recipient,
content, security, document type, date stamp, acknowledgement
requests, etc.  Our position from the beginning is that this
belongs to the transport layer rather than the document layer,
but now BII is requiring a platform-agnostic solution within a
single document family rather than the introduction of another
set of technologies.  My initial reaction was to adopt an
existing solution such as the UN/CEFACT Standard Business
Document Header (SBDH), as was done with Svefaktura in Sweden;
but the SBDH is a relatively small document structure that is
limited to a single document, and the requirement from BII is
support for sending a batch of related documents in a single
envelope.
PLB: This is especially needed in the tendering phase because
all the documents must be encrypted and prevented from being
opened until a particular time.  So there are specific business
requirements -- it's not just a transport issue.
RC: Collections of catalogues present other business
requirements relating to this.
GKH: An enveloping mechanism should be a separate deliverable
rather than an addition to the UBL schemas per se.  It won't
impact our NDRs regarding use of xsd:any if we address this in
a separate document.
PLB/TM: Our solution should be backward-compatible with
UN/CEFACT SBDH and should take advantage of the Swedish
experience.  We will be building on the existing specification
by creating a UBL profile of the SBDH with possibly some
extensions.  It must be possible to sign the header.
GKH: Which means that the header must have its own extension
mechanism.
TM: We also need to look at functional acknowledgement in
connection with this.
AGREED that we want to develop a messaging strategy for UBL
2.1 based on work now taking place in the BII Architecture
Group and that we will publish it like the digital signature
spec as a separate document that will be included in the UBL
2.1 distribution along with a section in the UBL 2.1
document itself.  It will be necessary to coordinate with
both the BII AG and the new OASIS BDX TC.
ACTION: PLB to line up participants for a team to interface
with BII and BDX; JB to put this on next week's agenda.
AGREED that we will aim to complete this item as part of
PRD3 and not aim for its delivery in PRD2.  TSC REPORT
TM: TSC has reached consensus on the two new document types.
There are about a dozen other outstanding issues left to be
resolved, but the TSC work is close to being done.  DIGITAL SIGNATURES
GKH: As noted in the Pacific call, the Security SC has accepted
the latest changes.  The revised materials for 2.1 may be ready
as soon as today.  UBL NDR WORK
Temporarily on hold.  NDR CHECK (NIST TOOL)

BH: Still pending.  2011 UBL TC F2F MEETING SCHEDULE
30 May - 3 June 2011
Ankara, Turkey, at Middle Eastern Technical University
AGREED that we will aim to have PRD2 completed or at least
well underway by the time of this meeting and therefore that
the main agenda item for Ankara will be PRD3, including
completion of the message envelope work and any items coming
out of PRD2.
October/November 2011
As we agreed some time ago, GKH is checking to see whether
we can secure a meeting venue in Ottawa.
(2011.01.05) AGREED to pick this up when GKH returns from
a break at the end of March (he will be gone for most of
the month).  If no more than 4-5 people plan to attend,
Crane can host the meeting in Kars.
So far we have JB, GKH, and possibly BH intending to
participate.  Anyone else?  TC CONCALL SCHEDULE
