Hi Pauline,
The following works ok for us (as an example - non-essential details removed):
<?xml version="1.0" encoding="UTF-8"?>
<catalog name="YOUR SITE OPeNDAP Catalog"
xmlns="http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0";
xmlns:xlink="http://www.w3.org/1999/xlink";>
<service name="yoursiteopendap" serviceType="OpenDAP"
base="http://www.yoursite.com/dods/nph-dods/dods-data/"/>
<datasetScan name="climatology-netcdf" path="climatology-netcdf"
location="http://www.yoursite.com/dods/nph-dods/dods-data/climatology-netcdf";>
<serviceName>yoursiteopendap</serviceName>
<crawlableDatasetImpl
className="thredds.crawlabledataset.CrawlableDatasetDods" />
</datasetScan>
<datasetScan name="bluelink" path="bluelink"
location="http://www.yoursite.com/dods/nph-dods/dods-data/bluelink";>
<serviceName>yoursiteopendap</serviceName>
<crawlableDatasetImpl
className="thredds.crawlabledataset.CrawlableDatasetDods" />
</datasetScan>
</catalog>
I'm not sure if its all documented somewhere - I worked it out the slow way by
poking around in the netcdf java code and hunting through the archives of the
thredds mailing list. There are also some trivial changes you need to make to
the code (in netcdf-java) to filter out some unwanted artifacts created when
the scan picks through the html from the OpenDAP server - otherwise you end up
with some strange, non-functional things in your catalog. Maybe there is a
better way to do the above?
By way of introduction, we want this sort of catalog to work as part of a
thredds metadata harvester I'm adding to GeoNetwork which produces ISO19115
metadata records and ISO19119 records for thredds services. Its nearly at the
stage where it is working reliably but there are a few more issues I need to
solve and I'm still learning about Thredds :-)
Cheers and I hope this helps,
Simon

Subject: [thredds] Running THREDDS on top of old OPeNDAP servers
Hi all,
I'm figuring out ways to serve data using THREDDS on top of old OPeNDAP
servers. I'm aware that you can configure datasets based on a URL, but
that's for a single file... (correct me if I'm wrong!) However, are
there ways to apply to an directory? Sort of like a datasetScan +
filters for a directory URL? When poking through the THREDDS catalog
XSD, there's a crawlableDatasetImpl element. Is that the sort of things
I need to look at?
Thanks,
-Pauline.
