 <div class="block">Enumeration of some metadata standards. A standard is defined by a set of Java interfaces
  in a specific package or sub-packages. For example the <a href="#ISO_19115">ISO 19115</a>
  standard is defined by <a href="http://www.geoapi.org">GeoAPI</a> interfaces in the
  <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/metadata/package-summary.html?is-external=true" class="externalLink"><code>org.opengis.metadata</code></a> package and sub-packages.

  <p>This class provides some methods operating on metadata instances through
  <a href="https://docs.oracle.com/javase/8/docs/api/java/lang/reflect/package-summary.html?is-external=true" class="externalLink">Java reflection</a>. The following rules are assumed:</p>

  <ul>
    <li>Metadata properties are defined by the collection of following getter methods found
        <strong>in the interface</strong>, ignoring implementation methods:
        <ul>
          <li><code>get*()</code> methods with arbitrary return type;</li>
          <li>or <code>is*()</code> methods with boolean return type.</li>
        </ul></li>
    <li>All properties are <cite>readable</cite>.</li>
    <li>A property is also <cite>writable</cite> if a <code>set*(…)</code> method is defined
        <strong>in the implementation class</strong> for the corresponding getter method.
        The setter method doesn't need to be defined in the interface.</li>
  </ul>

  An instance of <code>MetadataStandard</code> is associated to every <a href="AbstractMetadata.html" title="class in org.apache.sis.metadata"><code>AbstractMetadata</code></a> objects.
  The <code>AbstractMetadata</code> base class usually form the basis of ISO 19115 implementations but
  can also be used for other standards.

  <div class="section">Defining new <code>MetadataStandard</code> instances</div>
  Users should use the pre-defined constants when applicable.
  However if new instances need to be defined, then there is a choice:

  <ul>
    <li>For <em>read-only</em> metadata, <code>MetadataStandard</code> can be instantiated directly.
        Only getter methods will be used and all operations that modify the metadata properties
        will throw an <a href="UnmodifiableMetadataException.html" title="class in org.apache.sis.metadata"><code>UnmodifiableMetadataException</code></a>.</li>
    <li>For <em>read/write</em> metadata, the <a href="#getImplementation(java.lang.Class)"><code>getImplementation(Class)</code></a>
        method must be overridden in a <code>MetadataStandard</code> subclass.</li>
  </ul>

  <div class="section">Thread safety</div>
  The same <code>MetadataStandard</code> instance can be safely used by many threads without synchronization
  on the part of the caller. Subclasses shall make sure that any overridden methods remain safe to call
  from multiple threads, because the same <code>MetadataStandard</code> instances are typically referenced
  by a large amount of <a href="ModifiableMetadata.html" title="class in org.apache.sis.metadata"><code>ModifiableMetadata</code></a>.</div>

 <div class="block">Returns a view of the specified metadata object as a <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Map.html?is-external=true" title="class or interface in java.util" class="externalLink"><code>Map</code></a>.
  The map is backed by the metadata object using Java reflection, so changes in the
  underlying metadata object are immediately reflected in the map and conversely.

  <p>The map content is determined by the arguments: <code>metadata</code> determines the set of
  keys, <code>keyPolicy</code> determines their <code>String</code> representations of those keys and
  <code>valuePolicy</code> determines whether entries having a null value or an empty collection
  shall be included in the map.</p>

  <div class="section">Supported operations</div>
  The map supports the <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Map.html?is-external=true#put(K,V)" title="class or interface in java.util" class="externalLink"><code>put(…)</code></a> and <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Map.html?is-external=true#remove(java.lang.Object)" title="class or interface in java.util" class="externalLink"><code>remove(…)</code></a> operations if the underlying metadata object contains setter methods.
  The <code>remove(…)</code> method is implemented by a call to <code>put(…, null)</code>.
  Note that whether the entry appears as effectively removed from the map or just cleared
  (i.e. associated to a null value) depends on the <code>valuePolicy</code> argument.

  <div class="section">Keys and values</div>
  The keys are case-insensitive and can be either the JavaBeans property name, the getter method name
  or the <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/annotation/UML.html?is-external=true#identifier()" title="class or interface in org.opengis.annotation" class="externalLink">UML identifier</a>. The value given to a call
  to the <code>put(…)</code> method shall be an instance of the type expected by the corresponding setter method,
  or an instance of a type <a href="../util/ObjectConverters.html#find(java.lang.Class,java.lang.Class)">convertible</a>
  to the expected type.

  <div class="section">Multi-values entries</div>
  Calls to <code>put(…)</code> replace the previous value, with one noticeable exception: if the metadata
  property associated to the given key is a <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Collection.html?is-external=true" title="class or interface in java.util" class="externalLink"><code>Collection</code></a> but the given value is a single
  element (not a collection), then the given value is <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Collection.html?is-external=true#add(E)" title="class or interface in java.util" class="externalLink">added</a>
  to the existing collection. In other words, the returned map behaves as a <cite>multi-values map</cite>
  for the properties that allow multiple values. If the intent is to unconditionally discard all previous
  values, then make sure that the given value is a collection when the associated metadata property expects
  such collection.

  <div class="section">Disambiguating instances that implement more than one metadata interface</div>
  It is some time convenient to implement more than one interface by the same class.
  For example an implementation interested only in extents defined by geographic bounding boxes could implement
  <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/metadata/extent/Extent.html?is-external=true" title="class or interface in org.opengis.metadata.extent" class="externalLink"><code>Extent</code></a> and <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/metadata/extent/GeographicBoundingBox.html?is-external=true" title="class or interface in org.opengis.metadata.extent" class="externalLink"><code>GeographicBoundingBox</code></a>
  by the same class. In such case, it is necessary to tell to this method which one of those two interfaces
  shall be reflected in the returned map. This information can be provided by the <code>baseType</code> argument.
  That argument needs to be non-null only in situations where an ambiguity can arise; <code>baseType</code> can be null
  if the given metadata implements only one interface recognized by this <code>MetadataStandard</code> instance.</div>

 <div class="block">Returns the specified metadata object as a tree table.
  The tree table is backed by the metadata object using Java reflection, so changes in the
  underlying metadata object are immediately reflected in the tree table and conversely.

  <p>The returned <code>TreeTable</code> instance contains the following columns:</p>
  <ul class="verbose">
    <li><a href="../util/collection/TableColumn.html#IDENTIFIER"><code>TableColumn.IDENTIFIER</code></a><br>
        The <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/annotation/UML.html?is-external=true#identifier()" title="class or interface in org.opengis.annotation" class="externalLink">UML identifier</a> if any,
        or the Java Beans property name otherwise, of a metadata property. For example
        in a tree table view of <a href="iso/citation/DefaultCitation.html" title="class in org.apache.sis.metadata.iso.citation"><code>DefaultCitation</code></a>,
        there is a node having the <code>"title"</code> identifier.</li>

    <li><a href="../util/collection/TableColumn.html#INDEX"><code>TableColumn.INDEX</code></a><br>
        If the metadata property is a collection, then the zero-based index of the element in that collection.
        Otherwise <code>null</code>. For example in a tree table view of <code>DefaultCitation</code>, if the
        <code>"alternateTitle"</code> collection contains two elements, then there is a node with index 0
        for the first element and an other node with index 1 for the second element.

        <div class="note"><b>Note:</b>
        The <code>(IDENTIFIER, INDEX)</code> pair can be used as a primary key for uniquely identifying a node
        in a list of children. That uniqueness is guaranteed only for the children of a given node;
        the same keys may appear in the children of any other nodes.</div></li>

    <li><a href="../util/collection/TableColumn.html#NAME"><code>TableColumn.NAME</code></a><br>
        A human-readable name for the node, derived from the identifier and the index.
        This is the column shown in the default <a href="#toString()"><code>toString()</code></a> implementation and
        may be localizable.</li>

    <li><a href="../util/collection/TableColumn.html#TYPE"><code>TableColumn.TYPE</code></a><br>
        The base type of the value (usually an interface).</li>

    <li><a href="../util/collection/TableColumn.html#VALUE"><code>TableColumn.VALUE</code></a><br>
        The metadata value for the node. Values in this column are writable if the underlying
        metadata class have a setter method for the property represented by the node.</li>

    <li><a href="../util/collection/TableColumn.html#REMARKS"><code>TableColumn.REMARKS</code></a><br>
        Remarks or warning on the property value. This is rarely present.
        It is provided when the value may look surprising, for example the longitude values
        in a geographic bounding box spanning the anti-meridian.</li>
  </ul>

  <div class="section">Write operations</div>
  Only the <code>VALUE</code> column may be writable, with one exception: newly created children need
  to have their <code>IDENTIFIER</code> set before any other operation. For example the following code
  adds a title to a citation:

  <blockquote><pre>TreeTable.Node node = ...;                               <i><font color="gray">// The node for a DefaultCitation.</font></i>
 TreeTable.Node child = node.<b>newChild</b>();
 child.<b>setValue</b>(TableColumn.IDENTIFIER, <font color="orangered">"title"</font>);
 child.<b>setValue</b>(TableColumn.VALUE, <font color="orangered">"Le petit prince"</font>);
 <i><font color="gray">// Nothing else to do - the child node has been added.</font></i></pre></blockquote>

  Nodes can be removed by invoking the <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Iterator.html?is-external=true#remove()" title="class or interface in java.util" class="externalLink"><code>Iterator.remove()</code></a> method on the
  <a href="../util/collection/TreeTable.Node.html#getChildren()">children</a> iterator.
  Note that whether the child appears as effectively removed from the node or just cleared
  (i.e. associated to a null value) depends on the <code>valuePolicy</code> argument.
