Re: THREDDS Catalog Generator Error

Hi Mark,

Yeah, this is a bit weird. Your config file and the resulting file look fine.
They are both InvCatalog documents. The result doc has nested datasets, the leaf
datasets are accessible because they refer to <service> elements. The config
file contains only one dataset that does not refer to a <service> element but
contains a metadata record. The parser is spitting out this warning message
because it is treating the config file like an InvCatalog doc and the parser
thinks a dataset without child datasets or a reference to a service may be a

So, bottom line, the warning is something you should ignore.

Does that make sense?
