Hi Ben,
Thanks for the useful info and postings etc. Below you mention Andrew Wolfs' presentation on grid/Opendap - do you know where it is located?
Thx, Glenn

Hi,
GALEON participants who attended the OGC Technical Committee meeting
in Edinburgh can add to (or correct) this brief summary of the meeting
highlights from my GALEON perspective.
From the GALEON point of view, an important aspect of the meeting was
the fact that there appears to be agreement on (or at least not a lot
of vociferous opposition to) the approach we've proposed for revising
the binary encodings part of the WCS 1.1 specification. As a
reminder, the relevant proposed changes will make CF-netCDF one of the
supported encoding formats. The essence of the changes is provided in
two documents. The first summarizes the revised section of the spec
itself:
http://www.unidata.ucar.edu/projects/THREDDS/GALEON/CF-netCDFprofile/WCS_1.1_draft_SupportedFormats.htm
<http://www.unidata.ucar.edu/projects/THREDDS/GALEON/CF-netCDFprofile/WCS_1.1_draft_SupportedFormats.htm>
and the second is the draft WCS 1.1 application profile for encoding
CF-netCDF.
http://www.unidata.ucar.edu/projects/THREDDS/GALEON/CF-netCDFprofile/WCS-Encoding-Profile-For-CF-netCDFforPublic.htm
<http://www.unidata.ucar.edu/projects/THREDDS/GALEON/CF-netCDFprofile/WCS-Encoding-Profile-For-CF-netCDFforPublic.htm>
According to the revised WCS under consideration, an application
profile of this sort has to be approved by OGC for WCS encoding
formats. Note that the draft of the CF-netCDF application profile is
preceded by background information.
The OGC Technical Committee agreed to schedule an e-vote, "to begin on
or before August 15," for
adoption of 06-083r? as WCS 1.1.0. The OGC document 06-083 is the one
that contains the changes that will make CF-netCDF one of the official
encoding formats for WCS. In fact, it may be the only one with an
associated application profile. Discussions are still underway on a
few topics, but the WCS Revision Working Group will vote next week to
stop accepting change requests for WCS 1.1.
There were many additional interesting discussions and presentations
at the technical committee meetings, but I'll just mention two that
may be of special interest to some members of the GALEON community.
One is the fact that there is considerable interest in the OGC catalog
specification (CS-W). I think this is very important for WCS and
GALEON because the list of coverages returned in the WCS
getCapabilities request is not adequate to represent all the
information in THREDDS catalogs assciated with collections of netCDF
datasets. Another very interesting presentation was given by Andrew
Woolf describing a project getting underway at the UK NERC (Natural
Environment Research Council). It involves bringing together GRID
technologies for orchestrating services with OGC Web Processing
Services (WCS) and computational services associated with OPeNDAP,
e.g., the GDS (GRADS Data Server).
All in all -- a very productive meeting. Enough for now.
