    And also

    http://docs.oasis-open.org/ubl/prd1-UBL-2.1/mod/summary/reports/UBL-AllDocuments-2.1.html#Table_LocationCoordinate.Details

    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.
