Hi Rich:

scan only works on file directories right now. we are considering ways to 
extend it, but im not sure what you are intending here. Are the files available 
over HTTP using Accept-Range?

I dont suppose you can NFS mount the file system between the 2 machines for now?

THREDDS support:

Our web guy says as a federal agency, USGS is only allowed to use port 80, so we installed THREDDS on a different machine than our web server so we could use port 80 for THREDDS as well.

Can we use THREDDS on one server to aggregate OpenDAP files on another server using the <scan> feature?

We tried this, but it didn't work:

<catalog xmlns="http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0";

          xmlns:xlink="http://www.w3.org/1999/xlink";
          name="THREDDS-IDD OPeNDAP Data Server" version="1.0.1">

<service name="ncdods" serviceType="OPENDAP" base="/thredds/dodsC/" />

<dataset name="Adriatic Aggregation" ID="adria/sed038" urlPath="adria/sed038"> <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>

<aggregation dimName="ocean_time" type="joinExisting">

<scan location="http://stellwagen.er.usgs.gov/models/adria/sed038/"; suffix=".nc" />

</aggregation>
</netcdf>
</dataset>
</catalog>


But perhaps we did something else wrong.

Thanks,
Rich
