I'm using thredds 3.4 on tomcat 5.0.30. My content/thredds/catalog.xml contains: <catalogRef xlink:title="North Atlantic Class 1 - Best estimate and bulletins" xlink:href="dodsC/mersea-ip-class1-nat.xml"> <documentation type="summary"> DODS Data Prepared for the MERSEA IP EU Project. </documentation> <documentation type="simple" xlink:href="http://www.mersea.eu.org" xlink:title="MERSEA Project Web page"> </documentation> </catalogRef> Where is the documentation shown? Wouldn't it be better to have a <metadata inherited="true">...</metadata> inside <catalogRef> and let all the datasets in dodsC/mersea-ip-class1-nat.xml inherit them? Another way that would work for me was to have it like this: <dataset "container"> <!-- no ID on this --> <metadata inherited="true">...</metadata> <catalogRef ... /> </dataset> And then all the datasets in the catalogRef also inherit the metadata. I use catalogRef to avoid having to process all my large datasets unless specifically asked for, but they mainly have pretty much the same <authority>, <dataType>, <dataFormat>, <documentation>, <creator> and <publisher>. -- Bjørge Solli - Office:+47 55205847 cellph.:+47 91614343 Nansen Environmental and Remote Sensing Center - Bergen, Norway http://www.nersc.no Reception: +47 55205800 Dept.: Mohn-Sverdrup Center for Global Ocean Studies and Operational Oceanography
