The DAP2 Data Descriptor Object (DDS) is a data structure used by the DAP2 software to describe datasets and subsets of those datasets. The DDS may be thought of as the declarations for the data structures that will hold data requested by some DAP2 client. Part of the job of a DAP2 server is to build a suitable DDS for a specific dataset and to send it to the client. Depending on the data access API in use, this may involve reading part of the dataset and inferring the DDS. Other APIs may require the server simply to read some ancillary data file with the DDS in it.
On the server side, in addition to the data declarations, the DDS holds the clauses of any constraint expression that may have accompanied the data request from the DAP2 client. The DDS object includes methods for modifying the DDS according to the given constraint expression. It also has methods for directly modifying a DDS, and for transmitting it from a server to a client.
For the client, the DDS object includes methods for reading the persistent form of the object sent from a server. This includes parsing the ASCII representation of the object and, possibly, reading data received from a server into a data object.
Note that the class DDS is used to instantiate both DDS and DataDDS objects. A DDS that is empty (contains no actual data) is used by servers to send structural information to the client. The same DDS can becomes a DataDDS when data values are bound to the variables it defines.
For a complete description of the DDS layout and protocol, please refer to The OPeNDAP User Guide.
The DDS has an ASCII representation, which is what is transmitted from a DAP2 server to a client. Here is the DDS representation of an entire dataset containing a time series of worldwide grids of sea surface temperatures:
Dataset { Float64 lat[lat = 180]; Float64 lon[lon = 360]; Float64 time[time = 404]; Grid { ARRAY: Int32 sst[time = 404][lat = 180][lon = 360]; MAPS: Float64 time[time = 404]; Float64 lat[lat = 180]; Float64 lon[lon = 360]; } sst; } weekly;
If the data request to this dataset includes a constraint expression, the corresponding DDS might be different. For example, if the request was only for northern hemisphere data at a specific time, the above DDS might be modified to appear like this:
Dataset { Grid { ARRAY: Int32 sst[time = 1][lat = 90][lon = 360]; MAPS: Float64 time[time = 1]; Float64 lat[lat = 90]; Float64 lon[lon = 360]; } sst; } weekly;
Since the constraint has narrowed the area of interest, the range of latitude values has been halved, and there is only one time value in the returned array. Note that the simple arrays (lat
, lon
, and time
) described in the dataset are also part of the sst
Grid object. They can be requested by themselves or as part of that larger object.
See the The OPeNDAP User Guide, or the documentation of the BaseType class for descriptions of the DAP2 data types.

Returns a pointer to the named variable. If the name contains one or more field separators then the function looks for a variable whose name matches exactly. If the name contains no field separators then the function looks first in the top level and then in all subsequent levels and returns the first occurrence found. In general, this function searches constructor types in the order in which they appear in the DDS, but there is no requirement that it do so.
