Hi Mike,
Sorry about the documentation. I'll try to get that fixed up and make
our catalogs part of the documentation in some way. In the mean time,
below is a snippet from our NCEP model data catalog.
Hope that helps,
Ethan

I see that the motherlode server in fact has opendap (and NetcdfSubset) servers behind it's forecast model run views...
So is there any chance the server-side catalog.xml files from motherlode can be made public? I've been experimenting with catalog.xml versions for a few days, and simply can not get datasetFmrc to work correctly (neither can I get NetcdfSubset to give anything but a 404 error).
In light of the observation that the examples in the documentation on the Thredds web site tend to leave out important details, making them almost impossible to use as templates, it would be incredibly useful to see examples of actual production xml.
I imagine there's a large number of potential thredds administrators who simply
get turned off because it's so hard to get a first implementation working, so
sharing production xml could go a long way towards promulgating thredds.

Mike
Seems I've had had an extra bowl of Grumpy-Os this morning.

Subject: [thredds] datasetFmrc question
When I create a forecastModelRunCollection type aggregation, and put it in a
datasetFmrc TDS element, I get the collections of dataset views as suggested in
the TDS documentation, such as:
- Forecast Model Run Collection (2D time coordinates)
- Best Time Series
- [folder] Forecast Model Run/
- [folder] Constant Forecast Offset/
- [folder] Constant Forecast Date/
All the views appear as one would expect. However, the only dataset view with a OPENDAP
server behind it is the "Forecast Model Run Collection (2D time coordinates)".
Is this what I should expect, or should the other views also provide OPENDAP servers?
Thanks, Mike
