Hi Bruce,
One problem is that your catalog is not valid according to the
InvCatalog schema. The TDS is pretty lenient when reading catalogs
so I don't think any of this is causing the problem you are seeing.
But here are the details. Just a few changes fix it. At the catalog
level, service elements must come before dataset elements. The
datasetRoot element needs a location attribute instead of a
dirLocation attribute (either is allowed in datasetScan but not in
datasetRoot). Inside of datasets, access elements come after
metadata and dataSize elements. Also, metadata elements have to
come before dataset elements. I've attached a new version of your
catalog that fixes these problems.
Can you try the attached catalog and check for well-formed XML in
the linked resource and see how well that works?
I tried the modifications you suggested and got disappointing
results. I've posted the errors produced again at http://
www.ssec.wisc.edu/~brucef.
Your suggestions bring up a couple of questions regarding the schema:
1. Is it correct that the order in the schema is the _exact_ order
they must appear in the XML doc (if they appear of course)?
2. where is the definition for datasetRoot? It doesn't appear to
be in the schema.
3. there are some other elements, addDatasetSize for example, that
also don't seem to be in the schema.
You could just stick some text and an HTML link into a
documentation element:
<documentation>Other related datasets are available in this
datasets <a href="???">parent collection</a>.</documentation>
I see your point about the documentation. A description with the
additional xhtml anchor tag would probably work well, but I cannot
seem to get that to work either. The XML parser fails when it comes
across the anchor.
Unfortunately, the server is running on a machine that is not
available outside of SSEC. If it would be helpful I can run a
service on a machine that is available.
Thanks for your time,
Bruce
