Re: [galeon] [WCS-2.0.swg] CF-netCDF standards initiatives

I may be ignorant about these issues, so please forgive me if I am
completely out-of-line....but when I looked at the examples, I got
very concerned since the metadata needed to interpret the data values
in the "data files" is apparently not actually in the file, but
somewhere else.  We've been here before:  One of the single biggest
mistakes that the meteorological community made in defining a
distribution format for realtime, streaming data was BUFR -- because
the "tables" needed to interpret the contents of the files are
somewhere else....and sometimes, end users cannot find them!

NetCDF and ncML maintain the essential metadata within the files:
types, units, coordinates -- and I strongly urge you (or whomever) not
to make the  "BUFR mistake" again -- put the metadata into the files!
Do not require the end user to have to have an internet connection to
simply "read" the data....many people download the files and then
"take them along" when traveling, for example.

If I simply downloaded the file at
I would not be able to read it.  In fact, it looks like even if I also
got the "metadata" file at:
I would still not be able to read it, since it also refers to other
servers in the universe to obtain essential metadata.

That is my 2 cents worth....and I hope I am wrong about what I saw in
the examples....
