<p>This module is always present (cannot be removed) and provides a
simple and fast in-memory store with no persistence.  It is
the default store if no store name is given to the storage
constructors.</p>
<p>The memory store is not suitable for large in-memory models since
it does not do any indexing.  For that, use the
<a class="xref" href="redland-storage-module-hashes.html" title="Store 'hashes'">the section called “Store 'hashes'”</a> with
<code class="literal">hash-type</code> of <code class="literal">memory</code>.</p>
<p>The module provides optional contexts support enabled when
boolean storage option <code class="literal">contexts</code> is set.</p>
<p>Examples:</p>
<pre class="programlisting">
  /* Explicitly named memory storage */
  storage=librdf_new_storage(world, "memory", NULL, NULL);

  /* Default storage type, which is memory */
  storage=librdf_new_storage(world, NULL, NULL, NULL);

  /* In-memory store with contexts */
  storage=librdf_new_storage(world, NULL, NULL, "contexts='yes'");
</pre>
