All,More great inputs. Thanks all. Most of the concerns that were raised at the GO-ESSP meeting last week have now been expressed with good clarity in this discussion. Since this is a GALEON email list I suspect, that the GO-ESSP participants like myself generally only tune in with half an ear. (Thanks for permitting us to "butt in".) So there is a level of context about GALEON, itself, that may be missing to us. Namely, can someone provide a clear statement of the goals (mission) of the GALEON project? Is there any sense among GALEON participants that the goals should be modified in view of the WCS1.2 "core plus extensions" model?
I ask this in part after reflecting at length why the analogy of "the JPEG2000 community" felt amiss to me. JPEG200 is an IT standard that is emerging from the IT standards committee process. The metric of success for JPEG2000 is that it performs useful work for any community that can benefit from it. Marrying JPEG2000 to WCS is a potential win for both standards, where we view the goal as promoting specific technologies because they serve users generally.
The problems raised at the GO-ESSP meeting, by contrast, reflect the needs of a specific end user community (the scientists we serve) -- not a technology development community like ourselves. A specific and pressing example is the Intergovernmental Panel on Climate Change (IPCC), which is advancing an ambitious intercomparison of distributed climate model results (CMIP5). These model outputs will be characterized by huge size and nasty coordinate systems ("tripolar" oceans and "cube-sphere" atmospheres). It is incumbent upon the IT support community to make this ambitious effort successful (and many other efforts like it). And it is also incumbent upon us to help other less specialized communities (e.g. "climate impacts") participate in the broader interpretation of the model results. Does it fit into the GALEON mission statement to ask how GALEON can help in this effort? The climate community already has highly advanced (though admittedly incomplete) solutions for distributed model intercomparison using netCDF-CF-OPeNDAP. Where we have critical gaps to be filled is 1) making these model outputs available to outside communities (often GIS application users); and 2) bridging with European partners for whom an OGC-acceptable solution is a legally-mandated requirement. Can GALEON help us to succeed in these goals?

Hi Galeon activists, I'm following this discussion with great interest and curiosity.While trying to learn more about metocean world I have started collecting use cases mentioned.For those of you who have access to the WCS.SWG Wiki, the URL is https://portal.opengeospatial.org/twiki/bin/view/WCSrwg/GaleonNetwork Said page also collects some of the URLs the occasionally are posted here.I plan to sort of maintain and extend it, but any direct editing is most welcome too.-Peter
