Re: [thredds] Nesting serviceType="Compound"??



Ethan,
Along the same lines then, can <access> elements be inherited? Or is it bound only to the containing dataset and never to that dataset's children? 

Example:

  <dataset name="level1" ID="SingleFileWcs">
    <metadata inherited='true'>
       <access serviceName=dap />
    </metadata>
    <dataset name="level2_a" urlPath="wcs/foo" ID="wcs/foo" />
    <dataset name="level2_b" urlPath="wcs/foo" ID="wcs/foo" >
       <serviceName>otherService</serviceName>
    </dataset>
  </dataset>

Another question, about service inheritance.

Example:

      <serviceName>dap</serviceName>

          <serviceName>otherService</serviceName>
       </dataset>
  </dataset>


Is the dataset "level2_a" associated with the "dap" service??
No. Though it would be if the "dap" serviceName element were enclosed in 
an inherited metadata element, like this
<metadata inherited='true'><serviceName>dap</serviceName></metadata>


Is the dataset "level2_b" associated with the "dap" service??


No. Not even if the "dap" serviceName was inherited, because the
"otherService" association overrides any inherited association.
Is the dataset "level2_b" associated with the "otherService" service?? 

Yes, it is.
