Instead of specifying the URL of a single file on an OPeNDAP server, it is also possible to specify the URL of a catalog. The files on an OPeNDAP server are usually grouped in folders and for each folder there is a catalog file available. The catalog usually contains a list of files and subfolders, but can also refer to other catalog files. If the URL of a catalog file is specified for the import, then all files that are listed in the catalog will be imported. Other catalogs that are listed in the specified catalog are also imported recursively.
A catalog file is usually called catalog.xml. The URL of a catalog file can be obtained in the following way.
For a THREDDS opendap server: | First browse to a folder on the server. Then copy the current URL from the address line and replace "catalog.html" at the end of the url by "catalog.xml". |
For a HYRAX opendap server: | First browse to a folder on the server. Then click on the link "THREDDS Catalog XML" on the bottom of the page. Then copy the current URL from the address line. |
