Hi Katherine, > I'd like to be able to have one catalog.xml file with multiple > datasetscans each with a different filter to create a hierarchical > look for a bunch of datasets that are all under one directory Yes, that can be done. Your attempt is failing due to a small problem with your datasetScan elements. The path attribute values must be unique. (This is true across a TDS. Meaning that each path attribute for all datasetScan and datasetRoot elements in all config catalogs for a TDS must be unique.) The reason is that the path value is how the TDS matches an incoming request URL to a particular datasetScan. I'm including my changes to your example below. Notice also that I'm changing the ID value as well (dataset IDs have to be unique in a catalog but it is convenient to have the ID match the path in datasetScans). > <datasetScan name="My Pressure Level Data" > ID="ecmwf19972001" > path="ecmwf19972001" ID="pLevel-ecmwf19972001" path="pLevel-ecmwf19972001" > location="/data/ecmwf19972001/" harvest="true"> > <filter> > <include wildcard="ggap*.nc" /> > </filter> > </datasetScan> > <datasetScan name="My Surface Data" > ID="ecmwf19972001" > path="ecmwf19972001" ID="surf-ecmwf19972001" path="surf-ecmwf19972001" > location="/data/ecmwf19972001/" harvest="true"> > <filter> > <include wildcard="ggas*.nc" /> > </filter> > </datasetScan> Hope that makes sense. Let me know if you have any other questions or run into other problems. Ethan Ticket Details =================== Ticket ID: CUU-719322 Department: Support THREDDS Priority: Normal Status: Closed
