Hi Michael, Some extra information for you regarding what's available regarding thesauri. The BlueNet-MEST version of Geonetwork (most recent stable version 20090831 is available from http://anzlicmet.bluenet.utas.edu.au/wiki ) uses a heirarchical keywords system but not using RDF files as in 2.4.2 GN version. For the ISO19139-Marine Comminity Profile (MCP) metadata you can use a keyword list from the Global Change Master Directory (GCMD) science keywords list. Through the editor window you can select keyword triplets from a 3 level heirarchy .eg Oceans | Bathymetry | Seafloor Topography. This uses a special Java applet written by AIMS. For this to work you need to install the GCMD_keywords.xml file into the root directory and be using ISO19139MCP metadata. For ISO19139-ANZLIC profile metadata you can optionally choose hierarchical keywords from the ANZLIC theme keyword list. This uses an XML file in ISO CT_CodelistCatalogue format. To check this out install the BlueNet MEST on your PC and the GCMD keywords XML file in root. Then enter an ISO19139-MCP and a ISO19139-ANZLIC record. In the Identification section open up the 'Descritive Keywords'. For MCP click anywhere in the descritiptive keywords box and GCMD picker will pop up. For ANZLIC click in the other box to the right of the descriptive keywords box and choose a ANZLIC theme keyword from the list. I know this may not suit your requirements but it lets you know some alternative approaches.
