For example, to request the DAS object from the FNOC1 dataset at URI/GSO (a experiments dataset) you would append
`.das' to the URL: http://test.opendap.org/opendap/data/nc/fnoc1.nc.das.
Note: Many OPeNDAP clients supply these extensions for you so you don't need to append them (for example when using interfaces supplied by us or software re-linked with a OPeNDAP client-library). Generally, you only need to add these if you are typing a URL directly into a WWW browser.
Note: If you would like version information for this server but don't know a specific data file or data set name, use `/version' for the filename. For example: http://test.opendap.org/opendap/version will return the version number for the netCDF server used in the first example.
Suggestion: If you're typing this URL into a WWW browser and would like information about the dataset, use the `.info' extension.
If you'd like to see a data values, use the `.html' extension and submit a query using the customized form.
