Datanodes currently only produce 2 levels .../thredds/catalog.xml and .../thredds/esgcet/catalog.xml, but there would be no harm in having deeper nesting. What I think is less flexible is the constraint that "leaf-catalogs" contain a single container <dataset> element and a set of child <dataset> elements representing files and aggregations. This design is what LAS and other bits of ESGF rely on. General THREDDS allows you to mix catalogRef, container datasets and "real" datasets throughout the hierarchy.</span><span style="font-size: 11pt; font-family: Calibri, sans-serif; "><o:p></o:p></span></div></div><div><div style="margin-right: 0cm;
