Hi Steve, Stefano, John et al., This looks like a good starting point for harmonization. John Caron described one method of bridging between WCS and OPeNDAP: 1) Client discovers Coverage somehow 2) Client gets description of coverage via DescribeCoverage() 3) Client calls GetCoverage() 4) Server returns OPeNDAP URL to the result Another alternative (to complement, not replace, the above) might be to bypass GetCoverage() altogether: 1) Client discovers Coverage somehow 2) Client gets description of coverage via DescribeCoverage(). Description includes OPeNDAP URL to entire Coverage. 3) Client opts to use OPeNDAP to access subsets, without calling GetCoverage() at all. A client might choose this so that it can access more precise subsets, accepting the extra complexity. What do others think of this?

Hi Stefano et. al.,
Ben and I just made a step towards closing the loop on this conversation
through a telephone call. We found ourselves to be wildly in agreement.
:-) . Based upon your email below, it sounds like we may all be very
close to agreement (ah, the eternal optimist ;-) ...).
On the phone Ben and I agreed to propose the following two actions for the
short term. For everyone's comments, please:
GALEON should issue some form of announcement on its *intention* to
investigate encapsulating the OPeNDAP protocol within WCS (perhaps
following the template offered by JPIP). This announcement would be
intended to begin to erase the perception of a divide between OPeNDAP and
WCS as soon as possible.
We should conduct a quick investigation of whether there may be a simple
approach to embedding OPeNDAP into WCS that can be achieved as a very small
delta on the draft "WCS CF-netCDF profile document" (the subject line of
this dialog). See the PS below for details about this idea (especially John
Caron for TDS implementation thoughts)
