Re: [thredds] Catalog Validation


I removed them from me output and now when I check it:

I get back a HTML presentation view of my catalog.

Hi Nathan,

Actually, both types ("dataType" and "dataFormat") can contain any
string ("xsd:token"). The enumerated lists are just the current well
known values.

The XML Schema is a bit odd and not particularly obvious. Both types are
unions of "xsd:token" and a type that is a restriction of "xsd:token".

Best practice would be to omit if unknown. If known, decide on a string
to represent it and be consistent with that string. We are open to
adding values to the list.

Thanks Ethan! That's Exactly what I needed!

The validation output from my catalog contains 2 warnings (repeated
numerous times):

** warning: non-standard data type = unknown
** warning: non-standard dataFormat type = unknown
**Warning: Dataset (data/nc/ is selectable but no data type
declared in it or in a parent element
**Warning: Dataset (data/nc/
is selectable but no data type declared in it or in a parent element

The dataType and dataFormat types both use restricted vocabularies, but
neither offer an option for "unknown". In our service the source
dataFormat may not be known (it is simply a DAP type).

Is it better to omit these two metadata tags if their values are either
not known or not on the list of accepted values?

What's the best practice here?

Hi Nathan,

Here's the reference doc for TDS 4.x:

And here's a validation URL that works for your catalog:

I want to validate the THREDDS catalog output of my server.

I looked here:

And I tried this:

Which returned an HTML presentation of the catalog but no debugging
information. At this point I am guessing that any debugging output for
my catalog is living in the TDS output logs on

Is there another validation service that returns more information that I might use? Or is the solution for me to run my own TDS and use it to
validate catalogs from my THREDDS service?
