<hr><a name="_details"></a><h2>Detailed Description</h2>
The Data Attribute <a class="el" href="classlibdap_1_1Structure.html" title="Holds a structure (aggregate) type.">Structure</a> is a set of name-value pairs used to describe the data in a particular dataset. The name-value pairs are called the ``attributes''. The values may be of any of the DAP2 simple data types (<a class="el" href="classlibdap_1_1Byte.html" title="Holds a single byte.">Byte</a>, <a class="el" href="classlibdap_1_1Int16.html" title="Holds a 16-bit signed integer value.">Int16</a>, <a class="el" href="classlibdap_1_1UInt16.html" title="Holds an unsigned 16-bit integer.">UInt16</a>, <a class="el" href="classlibdap_1_1Int32.html" title="Holds a 32-bit signed integer.">Int32</a>, <a class="el" href="classlibdap_1_1UInt32.html" title="Holds a 32-bit unsigned integer.">UInt32</a>, <a class="el" href="classlibdap_1_1Float32.html" title="Holds a 32-bit floating point value.">Float32</a>, <a class="el" href="classlibdap_1_1Float64.html" title="Holds a 64-bit (double precision) floating point value.">Float64</a>, String and URL), and may be scalar or vector. Note that all values are actually stored as String data, making the easy to read/check using a web browser.<p>
A value may also consist of a set of other name-value pairs. This makes it possible to nest collections of attributes, giving rise to a hierarchy of attributes. DAP2 uses this structure to provide information about variables in a dataset. For example, consider the dataset used in the <a class="el" href="classlibdap_1_1DDS.html">DDS</a> example earlier.<p>
In the following example of a <a class="el" href="classlibdap_1_1DAS.html" title="Hold attribute data for a DAP2 dataset.">DAS</a>, several of the attribute collections have names corresponding to the names of variables in the <a class="el" href="classlibdap_1_1DDS.html">DDS</a> example. The attributes in that collection are said to belong to that variable. For example, the <code>lat</code> variable has an attribute ``units'' of ``degrees_north''.<p>
<pre>
Attributes {
GLOBAL {
String title "Reynolds Optimum Interpolation (OI) SST";
}
lat {
String units "degrees_north";
String long_name "Latitude";

}
}
</pre><p>
Attributes may have arbitrary names, although in most datasets it is important to choose these names so a reader will know what they describe. In the above example, the ``GLOBAL'' attribute provides information about the entire dataset.<p>
Data attribute information is an important part of the the data provided to a DAP2 client by a server, and the <a class="el" href="classlibdap_1_1DAS.html" title="Hold attribute data for a DAP2 dataset.">DAS</a> is how this data is packaged for sending (and how it is received).<p>
The <a class="el" href="classlibdap_1_1DAS.html" title="Hold attribute data for a DAP2 dataset.">DAS</a> class is simply a sequence of attribute tables and names. It may be thought of as the top level of the attribute hierarchy.<p>
