Dear all, Thanks for all this information - it's good to know that there is strong support for WCS1.0+ and I agree with the approach being taken (thanks to Andrew especially for summarizing the issues). Simple implementations are good! Is there a relationship here with the WCPS (Web Coverage Processing Service)? (Is Peter Baumann on this list?)

Hi all, I'd like to add a couple of general comments: In a broader picture, this is an interoperability experiment stemming from the Earth & Space Science Community needs; its implementation results, recommendations and request for change/enhancement might be extremely valuable for the geospatial information standardization and integration initiatives, such as the OGC and the CF-netCDF. In my opinion, in the next future, initiatives like WCS1.0+ will be promoted or supported by forum, such as: AGU-ESSI, EGU-ESSI, eGY, etc. In addition to GALEON phase 1, this effort was urged by the OGC-UNIDATA interoperability day conclusions, too. WCS 1.0 seems to be the only implemented specification, so far. In fact, the Earth & Space Science community asks for simple and "non-invasive" implementations; a possible solution might be to "clean" the quite loose WCS 1.0 specification, "slightly" improving it (Andrew beautifully listed the main points and the solutions which are under discussion and investigation). In fact, the WCS1.0+ philosophy is to discuss and keep complexity at the abstract level, coming up with "simple" implementations -based on implementation constraints which are effective and bearable for the ESS community. A valuable case in point is the asynch issue: in my opinion, WCS1.0+ started a first, open and great forum to discuss about asynchronous OWS, in general. As I anticipated, we're trying to summarize this discussion in a white paper in order to provide it as a contribute to the ESSI and OGC communities. Another valuable example seems to be the CF-netCDF profile. Regards, --Stefano
