 <div class="block">A connection to a metadata database in read-only mode. It can be either the database
  <a href="#getProvided()">provided by Apache SIS</a> with predefined ISO 19115 metadata,
  or another database specified at construction time.
  Metadata instances can be obtained as in the example below:

  <blockquote><pre>MetadataSource metadata = MetadataSource.<b>getProvided</b>();
 Format format = source.<b>lookup</b>(Format.<font color="green">class</font>, <font color="orangered">"PNG"</font>);</pre></blockquote>

  where <code>id</code> is the primary key value for the desired record in the <code>Format</code> table.

  <h2>Properties</h2>
  The constructor expects three Java arguments (the <a href="../MetadataStandard.html" title="class in org.apache.sis.metadata">metadata standard</a>,
  the <a href="https://docs.oracle.com/en/java/javase/16/docs/api/java.sql/javax/sql/DataSource.html" title="class or interface in javax.sql" class="external-link">data source</a> and the database schema) completed by an arbitrary amount
  of optional arguments given as a map of properties.
  The following keys are recognized by <code>MetadataSource</code> and all other entries are ignored:

  <table class="sis">
    <caption>Optional properties at construction time</caption>
    <tr><th>Key</th>                     <th>Value type</th>          <th>Description</th></tr>

    <tr><td><code>"classloader"</code></td>   <td><a href="https://docs.oracle.com/en/java/javase/16/docs/api/java.base/java/lang/ClassLoader.html" title="class or interface in java.lang" class="external-link"><code>ClassLoader</code></a></td> <td>The class loader to use for creating <a href="https://docs.oracle.com/en/java/javase/16/docs/api/java.base/java/lang/reflect/Proxy.html" title="class or interface in java.lang.reflect" class="external-link"><code>Proxy</code></a> instances.</td></tr>

  </table>

  <h2>Concurrency</h2>
  <code>MetadataSource</code> is thread-safe but is not concurrent. If concurrency is desired,
  multiple instances of <code>MetadataSource</code> can be created for the same <a href="https://docs.oracle.com/en/java/javase/16/docs/api/java.sql/javax/sql/DataSource.html" title="class or interface in javax.sql" class="external-link"><code>DataSource</code></a>.
  The <a href="#%3Cinit%3E(org.apache.sis.metadata.sql.MetadataSource)"><code>MetadataSource(MetadataSource)</code></a> convenience constructor can be used for this purpose.</div>
