Re: thredds catalog generator

Hi David,

Sorry haven't gotten back to you sooner. I'm out of office on vacation 
till Wed or Thursday but trying to stay on top of my email.

This is from our current documentation  at 
http://motherlode.ucar.edu:8080/thredds/docs/GettingStarted.html (is 
this what you are looking at?):

*(1)* <service name="thisDODS" serviceType="OpenDAP" base="/thredds/dodsC/">
     <datasetRoot path="test" location="content/testdata/" />
   </service>
				 
*(2)* <dataset name="Test Single Dataset" ID="testDataset" serviceName="thisDODS" 
      urlPath="test/testData.nc" />

Looks like you might be looking at something a bit out of date. Our 
distribution doesn't have a content/thredds/dodsC directory anymore. 
(This is one of the problems with the very basic way we deal with the 
content/thredds directory. It allows user changes  to survive 
thredds.war updates but it doesn't allow us to update things in 
content/thredds.)

Anyway, the basics of the above section of the document is that in the 
dataset, the "test" part of the urlPath matches the datasetRoot path 
value. This means that the dataset URL 
(http://server:port/thredds/dodsC/test/testData.nc) matches the "test" 
datasetRoot and the server looks in the "content/testdata" location for 
the testData.nc file. So, in this case the "test" part of the URL isn't 
actually represented at all in the directory location, it is merely a 
mapping between the url and the correct file/directory location.

Does that make sense?
