public class DefaultMetadata extends ISOMetadata implements Metadata
Root entity which defines metadata about a resource or resources. The following properties are mandatory or conditional (i.e. mandatory under some circumstances) in a well-formed metadata according ISO 19115:

## Localization

When this object is marshalled as an ISO 19139 compliant XML document, the value given to the `setLanguage(Locale)` method will be used for the localization of `InternationalString` and `CodeList` instances of in this `DefaultMetadata` object and every children, as required by INSPIRE rules. If no language were specified, then the default locale will be the one defined in the `XML​.LOCALE` marshaller property, if any.

## Limitations

- Instances of this class are not synchronized for multi-threading. Synchronization, if needed, is caller's responsibility.
- Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS. For long term storage, use `XML` instead.

- ## Constructor Details

  - ### DefaultMetadata

    public DefaultMetadata()
    Creates an initially empty metadata.

  - ### DefaultMetadata

    public DefaultMetadata(ResponsibleParty contact, Date dateStamp, Identification identificationInfo)
    Creates a meta data initialized to the specified values.
    Parameters:
      `contact` - party responsible for the metadata information.
      `dateStamp` - date that the metadata was created.
      `identificationInfo` - basic information about the resource to which the metadata applies.

  - ### DefaultMetadata

    public DefaultMetadata(Metadata object)
    Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, since the other metadata contained in the given object are not recursively copied.
    Parameters:
      `object` - the metadata to copy values from, or `null` if none.
    See Also:
      - `castOrCopy(Metadata)`

- ## Method Details

  - ### castOrCopy

    public static DefaultMetadata castOrCopy(Metadata object)
    Returns a SIS metadata implementation with the values of the given arbitrary implementation. This method performs the first applicable action in the following choices:
    - If the given object is `null`, then this method returns `null`.
    - Otherwise if the given object is already an instance of `DefaultMetadata`, then it is returned unchanged.
    - Otherwise a new `DefaultMetadata` instance is created using the copy constructor and returned. Note that this is a shallow copy operation, since the other metadata contained in the given object are not recursively copied.

    #### Use case

    This method is useful before XML marshalling or serialization, which may not be supported by all implementations. However the returned metadata is not guaranteed to be editable. For editable metadata, see `deepCopy(Metadata)`.
    Parameters:
      `object` - the object to get as a SIS implementation, or `null` if none.
    Returns:
      a SIS implementation containing the values of the given object (may be the given object itself), or `null` if the argument was null.

  - ### deepCopy

    public static DefaultMetadata deepCopy(Metadata object)
    Returns an editable copy of the given metadata. All children are also copied. This method is more expensive than `castOrCopy(Metadata)` because the copy is unconditional and much deeper. However the result is guaranteed to be editable.

    #### Use case

    Metadata returned by `Resource​.getMetadata()` are typically unmodifiable. This `deepCopy(…)` method is useful for completing those metadata with new elements, for example before insertion in a catalog.
    Parameters:
      `object` - the metadata to copy, or `null` if none.
    Returns:
      a deep copy of the given object, or `null` if the argument was null.
    Since:
      1.1
    See Also:
      - `ModifiableMetadata​.deepCopy(State)`
      - `ModifiableMetadata​.State​.EDITABLE`

  - ### getMetadataIdentifier

    @UML(identifier="metadataIdentifier", obligation=OPTIONAL, specification=ISO_19115) public Identifier getMetadataIdentifier()
    Returns a unique identifier for this metadata record.
    Note: OGC 07-045 (Catalog Service Specification — ISO metadata application profile) recommends usage of a UUID (Universal Unique Identifier) as specified by IETF to ensure identifier’s uniqueness.
    Returns:
      unique identifier for this metadata record, or `null`.
    Since:
      0.5

  - ### setMetadataIdentifier

    public void setMetadataIdentifier(Identifier newValue)
    Sets the unique identifier for this metadata record.
    Parameters:
      `newValue` - the new identifier, or `null` if none.
    Since:
      0.5

  - ### getFileIdentifier

    @Deprecated public String getFileIdentifier()
    Deprecated.
    As of ISO 19115:2014, replaced by `getMetadataIdentifier()` in order to include the codespace attribute.
    Returns the unique identifier for this metadata file.
    Specified by:
      `getFileIdentifier` in interface `Metadata`
    Returns:
      unique identifier for this metadata file, or `null`.

  - ### setFileIdentifier

    @Deprecated public void setFileIdentifier(String newValue)
    Deprecated.
    As of ISO 19115:2014, replaced by `setMetadataIdentifier(Identifier)`
    Sets the unique identifier for this metadata file.
    Parameters:
      `newValue` - the new identifier, or `null` if none.

  - ### getLocalesAndCharsets

    @UML(identifier="defaultLocale+otherLocale", obligation=CONDITIONAL, specification=ISO_19115) public Map<Locale,Charset> getLocalesAndCharsets()
    Returns the language(s) and character set(s) used for documenting metadata. The first entry in iteration order is the default language and its character set. All other entries, if any, are alternate language(s) and character set(s) used within the resource.

    Unless another locale has been specified with the `XML​.LOCALE` property, this `DefaultMetadata` instance and its children will use the first locale returned by this method for marshalling `InternationalString` and `CodeList` instances in ISO 19115-2 compliant XML documents.

    Each (`Locale`, `Charset`) entry is equivalent to an instance of ISO 19115 `PT_Locale` class. The language code and the character set are mandatory elements in ISO standard. Consequently this map should not contain null key or null values, but Apache SIS implementations is tolerant for historical reasons. The same character set may be associated to many languages.

    Returns:
      language(s) and character set(s) used for documenting metadata.
    Since:
      1.0

  - ### setLocalesAndCharsets

    public void setLocalesAndCharsets(Map<? extends Locale,? extends Charset> newValues)

    Parameters:
      `newValues` - the new language(s) and character set(s) used for documenting metadata.
    Since:
      1.0
