Hi Ben, A couple of comments:1) In my opinion, your draft ( http://www.unidata.ucar.edu/projects/THREDDS/GALEON/netCDFprofile-short.htm) is a very good CF-netCDF profile specification. The other document (http://www.unidata.ucar.edu/projects/THREDDS/GALEON/WCSnetCDFencoding.htm) has another scope: to specify how to map the CF-netCDF model into the ISO 19123 model (i.e. the coverage model). I think your new document is complementary to the old one, since it specifies the CF-netCDF model to be mapped.
2) the ncML-GML is the XML encoding of the mapping rules introduced in the old document.

Hi, One of the problems we ran into in attempting to write a profile document that maps between the characteristics of CF-netCDF and WCS is that WCS, netCDF, and CF are all undergoing revisions. Consequently the mapping between the two realms will be constantly out of date as any of the elements evolves. One way to avoid much of this built-in obsolescence is to construct a minimalist CF-netCDF encoding format document that consists mainly of pointers to the up-to-date sources of information relating to netCDF and the associated CF conventions. For someone working on a WCS client or server for the CF-netCDF encoding format, this document should be what is needed to get started. It provides brief descriptions of the technologies and pointers to -- documentation -- code -- support mechanisms -- descriptions of the "what, where, when" metadata. I put a draft at: http://www.unidata.ucar.edu/projects/THREDDS/GALEON/netCDFprofile-short.htm for comparison with the previous attempt: http://www.unidata.ucar.edu/projects/THREDDS/GALEON/WCSnetCDFencoding.htm At the other end of the spectrum are full, formal GML-based specifications that will eventually come from the ncML-GML and CSML initiatives. Let's discuss this during the teleconference tomorrow morning. -- Ben
