TSCers,
Please take note of the item below dealing
with Location. Need to consider this as we discuss area coordinates on our call.

Points made in the discussion of this topic included the
following:
- The issue was originally raised in August 2009.
- In UBL 2.0, only Address has location
coordinates. The
original use case was delivery to a large
factory that has a
single street address; the GPS coordinates
enable reference
to a specific loading dock.
- All coordinate pairs imply an area of unknown size
(consider
coordinates given to the nearest minute
rather than the
nearest second).
- Multiple coordinate pairs convey some kind of
information
about a boundary, but it's not clear
exactly what kind of
information that is; for example:
Do four pairs of
coordinates describe a trapezoid or an
hourglass?
Do three pairs of
coordinates describe a circle or a
triangle?
What do two pairs of
coordinates describe?
- As defined in PRD1, SubsidiaryLocation (i.e., a
location
within a location) is not a specialization
of Location; it
probably should be.
AGREED as follows:
1. An Address can only contain one LocationCoordinate (no
change).
2. Change Location to contain 0..n LocationCoordinates.
3. Add InformationURI to Location.
4. Make SubsidiaryLocation an ASBIE to Location, cardinality
0..n, and remove the ABIE called
SubsidiaryLocation.
ACTION: TM to send to Arianna for updates in eDoCreator.
AGREED that the semantic ambiguity attending multiple
location
coordinates can be resolved through use of the Description
and
Conditions elements under Location.
[Note: I did not notice until typing up these minutes that
the
element named LocationCoordinate actually contains two
coordinates, one for latitude and one for longitude.
Each of
these is an ordinate, and together they are co-ordinates.
Unfortunately, this error goes back to 2.0, so we're stuck
with
it.]
MESSAGE ENVELOPE
GKH has volunteered to co-chair the task group, but he wants
a
co-chair to handle business requirements.
AGREED to accept TM's offer to co-chair
with the
understanding that the task group is
developing a messaging
strategy for the UBL user community as a
whole that will
identify requirements and recommend
suitable technologies
for satisfying those requirements.
AGREED to add Andrea to the task group.
