If suffix is not a standard part of a service call, then clients will not know how to construct a url out of a base, middle, and suffix -- if they cannot construct the urls, then compound services cannot be centrally specified and referenced multiple times below. My example: http://iridl.ldeo.columbia.edu/SOURCES/.LEVITUS94/thredds.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE catalog SYSTEM "http://iridl.ldeo.columbia.edu/thredds.dtd"> <catalog> <service ID="IngridDataset" serviceType="Compound" base="http://iridl.ldeo.columbia.edu/"> <service serviceType="DODS" suffix="dods"/> <service serviceType="Catalog" suffix="thredds.xml"/> </service> <collection name="LEVITUS94"> <attribute name="fullname" value="LEVITUS94"/> <access serviceID="IngridDataset" urlPATH="SOURCES/.LEVITUS94/"/> <attribute name="references" value="Conkright:etal1994 Levitus:Boyer1994a Levitus:etal1994 Levitus:Boyer1994c"/> <documentation>LEVITUS94: World Ocean Atlas 1994, an atlas of objectively analyzed fields of major ocean parameters</documentation> <documentation xlink:href="http://iridl.ldeo.columbia.edu/SOURCES/.LEVITUS94/.dataset_documentation.html"/> <documentation xlink:href="http://iridl.ldeo.columbia.edu/SOURCES/.LEVITUS94/.oceanviews.html" title="oceanviews"/> <documentation xlink:href="http://iridl.ldeo.columbia.edu/SOURCES/.LEVITUS94/.oceanviews2.html" title="oceanviews2"/> <documentation xlink:href="http://iridl.ldeo.columbia.edu/SOURCES/.LEVITUS94/.Zmix.html" title="Zmix"/> <dataset name="ANNUAL"> <access serviceID="IngridDataset" urlPATH="SOURCES/.LEVITUS94/.ANNUAL/"/> </dataset> <dataset name="MONTHLY"> <access serviceID="IngridDataset" urlPATH="SOURCES/.LEVITUS94/.MONTHLY/"/> </dataset> <dataset name="SEASONAL"> <access serviceID="IngridDataset" urlPATH="SOURCES/.LEVITUS94/.SEASONAL/"/> </dataset> </collection> </catalog> Each access specifies part of the url: the suffix and base are necessary to complete the url. Compound services are not useful otherwise. > > Considering this is the current DTD acceptable to you till the next round > of > changes? > No, it is not. Until I can reference usefully a compound service, I will be unable to use the standard. Benno
