Hi, Aplologies to those of you who've already seen this several times on other lists, but I've gotten enough questions from THREDDS collaborators that I thought I should send it to this list as well. As some of you may be aware, I'm the official UCAR representative to the Open Geospatial Consortium (OGC) technical committee. A week ago I attended my second technical committee meeting (hosted by and at the U.N. this time.) The main highlight for us was the fact that Lorenzo Bigagli (Stefano's colleague at the U of Florence) and I were given an hour on the agenda, at which we proposed an Interoperability Experiment (IE) that in essence proposes to extend the Web Coverage Service (WCS) protocol with a gateway for serving data from THREDDS-integrated servers based on THREDDS, netCDF. Common Data Model, OPeNDAP, ADDE technology via the WCS interface. On the prototype servers, the datasets will be delivered as "coverages" encoded in geoTIFF (already operating in our WCS), NcML-GML (the work of the U of Florence group), and netCDF (a proposed addition to the current list of 5 OGC "blessed" binary encodings.) I've attempted to summarize the approach we're taking with this WCS Gateway in: http://my.unidata.ucar.edu/content/projects/THREDDS/OGC/WCS-THREDDS%20Gateway.htm This description was created before the TC meeting so it is somewhat out of date, but I hope to add the powerpoints that Lorenzo and I used and examples of the NcML and NcML-GML as soon as I get a chance, but I thought you would want to see what we're up to now. We are now thinking of calling this initiative GALON (Gateway for Atmosphere Ocean Land netCDF). I'll attach a list of OGC technical committee members who expressed interest in participating in the IE. -- Ben Liping Di (before the meeting), LAITS, George Mason University address@hidden Frank Warmerdam, consultant who works with OPeNDAP and CADcorp address@hidden Martin Daley, CADcorp, WCS client software address@hidden Chris Higgins, EDINA, Edinburgh U., who is part of the UK NERSC initiative address@hidden Clemens Portele, Interactive Instruments, GML expert address@hidden Lucia Lovison-Golob, Harvard U., mainly interested in educational applications address@hidden Guenther Pichler, OGC address@hidden Dr, Peter Baumann, International Univ., Bremen address@hidden Mike Botts, U of Alabama Huntsville, has a WCS client that handles 3D datasets address@hidden Simon Evans, ESRI address@hidden Prof. Dr. Ralf Denzer, FachbereichGrandlagen, Infomatik Sensortechnik Ralf. address@hidden Those are the names and addresses I have. I believe the people at the Canadian firm Galdos are interested in the NcML-GML but Ron Lake was not at the meeting. IONIC would also seem to be a company that should be interested, but I don't have any contacts. Lorenzo may have others names as well.
