Hi Shawn,

I apologize for not being able to help you out more quickly with your
inquiries because we are shorthanded at the moment (I am on travel in
Colombia and others are not available for other reasons).

The LDM utility 'notifyme' is a great resource to learn how to use.
It can tell you what you are getting AND what your upstream is getting.
Plus, its output contains the LDM/IDD Product IDs that you will setting
up extended regular expressions to match against.  An LDM installation
contains man pages for all LDM utilities, so that is the first place
to look (~ldm/share/man).

re:

'notifyme' allows you to save its output in a disk file so you can
peruse the information more at your leisure.  Here is one quick
example:

<as 'ldm'>
cd ~ldm
notifyme -vl logs/conduit.log -f CONDUIT     <- what you are getting
notifyme -vl logs/upstreamconduit.log -f CONDUIT -h <your upstream feed host>

Of course, you have to let this/these run for awhile in order to capture
enough headers to get the full flavor of what is there.

The other thing to do is review the pattern-action files that are
delivered with packages like GEMPAK, McIDAS and THREDDS.

Cheers,

Tom
