Greetings,
Any idea how many people are using the UNIDATA's NetCDF Attribute
Convention for Dataset Discovery??
If Roy's site is the primary (only?) example of it in actual use, and
we accept Benno's point that the name attribute Metadata_Conventions
is redundant, should we not consider amending the draft to change the
attribute name from Metadata_Conventions to Conventions?
(Assuming that it hasn't been push passed the draft spec: Dataset
Discovery NetCDF Attribute Convention)
If we don't change it might we amend the draft to explicitly make the
attributes Metadata_Conventions and Conventions synonymous?

There are metadata in our files that follows all of those
conventions. In trying to relay that act, we felt this was the best
way to relay that fact. So you will find the metadata required for
CF, the Coastwatch conventions, and the Unidata Data Discovery
Conventions.

OK, again trying desperately to understand your cryptic e-mails,
http://thredds1.pfeg.noaa.gov/thredds/dodsC/satellite/SW/chla/
1day.das
has many of those attributes. You did, however, say
String Conventions "COARDS, CF-1.0, Unidata Dataset Discovery v1.0,
CWHDF";
whereas the document suggested looking for
String Metadata_Conventions = "Unidata Dataset Discovery v1.0";
What you are doing, of course, makes sense. Did the original
document
get corrected over time?

No we use it extensively. Look at any of he satellite data at
our TDS (http://oceanwatch.pfeg.noaa.gov/thredds/catalog.html).
It is just since this is not automatically produced by the TDS
that we have a program of our own that generates our catalogs.

So, to be really concrete, despite this convention of using
netcdf attributes to insert metadata which you just pointed us
to, you don't use it at all, you just scan your netcdf files
yourself and generate the TDS XML directly.

We did this "by hand" (well actually we have a program that does
it) in generating our catalogs not certain ow others do it.

Roy,
Briefly scanning that page it looks like this gist of it is that
one could use NcML to add/complete a "Unidata Dataset Discovery
v1.0" set of metadata to a data set. THis could then be
harvested by the TDS, or by other software that understood the
"Unidata Dataset Discovery v1.0" convention.
Is that the general idea?

Greetings,
I have some questions about the origin of the
thredds:geospaptialCoverage element that is commonly found in
THREDDS catalogs. It is my understanding that:
- The TDS can generate this metadata element by interrogating
certain types of source data files.
- People that write their own THREDDS catalog files to be
served by the TDS can add the thredds:geospaptialCoverage
metadata directly to their catalogs (using whatever process
they wish).
Is the thredds:geospaptialCoverage also something that can be
added through normal channels in NcML augmented data sets?
