    **************************************************************************** Creating a CGImageMetadataTag **************************************************************************** [@function] CGImageMetadataTagCreate
    Creates a new CGImageMetadataTag [@link] CGImageMetadataCopyStringValueWithPath @/link or [@link] CGImageMetadataSetValueWithPath @/link.
    
    Parameters:
    
    xmlns - The namespace for the tag. The value can be a common XMP namespace defined above, such as kCGImageMetadataNamespaceExif, or a CFString with a custom namespace URI. Custom namespaces must be a valid XML namespace. By convention, namespaces should end with either '/' or '#'. For example, exif uses the namespace "http://ns.adobe.com/exif/1.0/".
    
    prefix - An abbreviation for the XML namespace. The value can be NULL if the namespace is defined as a constant. Custom prefixes must be a valid XML name. For example, the prefix used for "http://ns.adobe.com/exif/1.0/" is "exif". The XMP serialization of the tag will use the prefix. Prefixes are also important for path-based CGImageMetadata functions, such as
    
    name - The name of the tag. It must be a valid XMP name.
    
    type - The type of the tag's value. Must be a constant from @link CGImageMetadataType @/link.
    
    value - The value of the tag. Allowable CFTypes include CFStringRef, CFNumberRef, CFBooleanRef, CFArrayRef, and CFDictionaryRef. The CFType of 'value' must correspond to the 'type'. The elements of a CFArray must be either a CFStringRef or CGImageMetadataTagRef. The keys of a CFDictionary must be CFStringRefs with valid XMP names. The values of a CFDictionary must be either CFStringRefs or CGImageMetadataTagRefs. A shallow copy of the value is stored in the tag. Therefore, modifying a mutable value after the tag is created will not affect the tag's value.
    
    Returns:
    
    Returns a pointer to a new CGImageMetadataTag. Returns NULL if a tag could not be created with the specified parameters.

    [@function] CGImageMetadataTagCopyValue
    Returns a shallow copy of the tag's value
    This function should only be used to read the tag's value. CGImageMetadataCopyTagWithPath returns a copy of the tag (including a copy of the tag's value). Therefore mutating a tag's value returned from this function may not actually mutate the value in the CGImageMetadata. It is recommended to create a new tag followed by CGImageMetadataSetTagWithPath, or use CGImageMetadataSetValueWithPath to mutate a metadata value.
  - CGImageMetadataTagGetType

    [@function] CGImageMetadataTagGetType
    Get the type of the CGImageMetadataTag
    
    Returns:
    
    Returns a CGImageMetadataType constant for the CGImageMetadataTag. This is primarily used to determine how to interpret the tag's value.
  - CGImageMetadataTagCopyQualifiers
```
public static CFArrayRef CGImageMetadataTagCopyQualifiers(CGImageMetadataTagRef tag)
```
    [@function] CGImageMetadataTagCopyQualifiers
    Return a copy of the tag's qualifiers
    XMP allows properties to contain supplemental properties called qualifiers. Qualifiers are themselves CGImageMetadataTags with their own namespace, prefix, name, and value. A common use is the xml:lang qualifier for elements of an alternate-text array.
    
    Returns:
    
    Returns a copy of the array of qualifiers. Elements of the array are CGImageMetadataTags. Returns NULL if the tag does not have any qualifiers. The copy is shallow, the qualifiers are not deep copied.

```
    [@function] CGImageMetadataCopyTagWithPath
    Searches for a specific CGImageMetadataTag in a CGImageMetadataRef
    This is the primary function for clients to obtain specific metadata properties from an image. The 'path' mechanism provides a way to access both simple top-level properties, such as Date & Time, or complex deeply-nested properties with ease.
    Parameters:
    
    metadata - A collection of metadata tags.
    
    parent - A parent tag. If NULL, the path is relative to the root of the CGImageMetadataRef (i.e. it is not a child of another property). If the parent is provided, the effective path will be the concatenation of the parent's path and the 'path' parameter. This is useful for accessing array elements or structure fields inside nested tags.
    path - A string representing a path to the desired tag. Paths consist of a tag prefix (i.e. "exif") joined with a tag name (i.e. "Flash") by a colon (":"), such as CFSTR("exif:Flash"). Elements of ordered and unordered arrays are accessed via 0-based indices inside square [] brackets. Elements of alternate-text arrays are accessed by an RFC 3066 language code inside square [] brackets. Fields of a structure are delimited by a period, '.'. Qualifiers are delimited by the '?' character. Only tags with string values (kCGImageMetadataTypeString) are allowed to have qualifiers - arrays and structures may not contain qualifiers.
    If parent is NULL, a prefix must be specified for the first tag. Prefixes for all subsequent tags are optional. If unspecified, the prefix is inherented from the nearest parent tag with a prefix. Custom prefixes must be registered using @link CGImageMetadataRegisterNamespaceForPrefix @/link prior to use in any path-based functions.
    Examples:
    
    'path' = CFSTR("xmp:CreateDate")
    
    'path' = CFSTR("exif:Flash.Fired")
    
    'parent' = tag at path CFSTR("exif:Flash"), path = CFSTR("exif:Fired") (equivilent to previous)
    
    'path' = CFSTR("exif:Flash.RedEyeMode")
    
    'path' = CFSTR("dc:title")
    
    'path' = CFSTR("dc:subject")
    
    'path' = CFSTR("dc:subject[2]")
    
    'parent' = tag at path CFSTR("dc:subject"), path = CFSTR("[2]") (equivilent to previous)
    
    'path' = CFSTR("dc:description[x-default])"
    
    'path' = CFSTR("dc.description[de])"
    
    'path' = CFSTR("dc.description[fr])"
    
    'path' = CFSTR("foo:product)"
    
    'path' = CFSTR("foo:product?bar:manufacturer)"
    Returns:
    
    Returns a copy of CGImageMetadataTag matching 'path', or NULL if no match is found. The copy of the tag's value is shallow. Tags copied from an immutable CGImageMetadataRef are also immutable. Because this function returns a copy of the tag's value, any modification of the tag's value must be followed by a CGImageMetadataSetTagWithPath to commit the change to the metadata container.

```
    [@function] CGImageMetadataCopyStringValueWithPath
    Searches for a specific tag in a CGImageMetadataRef and returns its string value.
    This is a convenience method for searching for a tag at path and extracting the string value.
    
    Parameters:
    
    metadata - A collection of metadata tags.
    
    parent - A parent tag. If NULL, the path is relative to the root of the CGImageMetadataRef (i.e. it is not a child of another property).
    
    path - A string with the path to the desired tag. Please consult the documentation of @link CGImageMetadataCopyTagWithPath @/link for information about path syntax.
    
    Returns:
    
    Returns a string from a CGImageMetadataTag located at 'path'. The tag must be of type kCGImageMetadataTypeString or kCGImageMetadataTypeAlternateText. For AlternateText tags, the element with the "x-default" language qualifier will be returned. For other types, NULL will be returned.

```
    **************************************************************************** Functions for modifying a CGMutableImageMetadataRef **************************************************************************** *! @functiongroup Modifying a CGMutableImageMetadataRef [@function] CGImageMetadataRegisterNamespaceForPrefix
    Associates an XMP namespace URI with a prefix string.
    This allows ImageIO to create custom metadata when it encounters an unrecognized prefix in a path (see CGImageMetadataCopyTagWithPath for more information about path syntax). A namespace must be registered before it can be used to add custom metadata. All namespaces found in the image's metadata, or defined as a constant above, will be pre-registered. Namespaces and prefixes must be unique.
    
    Returns:
    
    Returns true if successful. Returns false and sets 'err' if an error or conflict occurs.

```
    [@function] CGImageMetadataSetTagWithPath
    Sets the tag at a specific path in a CGMutableImageMetadata container or a parent tag
    This is the primary function for adding new metadata tags to a metadata container, or updating existing tags. All tags required to reach the final tag (at the end of the path) will be created, if needed. Tags will created with default types (ordered arrays). Creating tags will fail if a prefix is encountered that has not been registered. Use [@link] CGImageMetadataRegisterNamespaceForPrefix @/link to associate a prefix with a namespace prior to using a path-based CGImageMetadata function. Note that if a parent tag is provided, the children of that tag reference will be modified, which may be a different reference from the tag stored in the metadata container. Since tags are normally obtained as a copy, it is typically neccesary to use CGImageMetadataSetTagWithPath to commit the changed parent object back to the metadata container (using the parent's path and NULL for the parent). [@link] CGImageMetadataCreateMutable @/link to obtain a mutable metadata container.
    
    Parameters:
    
    metadata - A mutable collection of metadata tags. Use @link CGImageMetadataCreateMutableCopy @/link or
    
    parent - A parent tag. If NULL, the path is relative to the root of the CGImageMetadataRef (i.e. it is not a child of another property). Note that if a parent tag is provided, the children of that tag reference will be modified, which may be a different reference from the tag stored in the metadata container. Since tags are normally obtained as a copy, it is typically neccesary to use CGImageMetadataSetTagWithPath to commit the changed parent object back to the metadata container (using the parent's path and NULL for the parent).
    
    path - A string with the path to the desired tag. Please consult the documentation of @link CGImageMetadataCopyTagWithPath @/link for information about path syntax.
    
    tag - The CGImageMetadataTag to be added to the metadata. The tag will be retained.
    
    Returns:
    
    Returns true if successful, false otherwise.

```
    [@function] CGImageMetadataSetValueWithPath
    Sets the value of the tag at a specific path in a CGMutableImageMetadataRef container or a parent tag
    This function is used to add new metadata values to a metadata container, or update existing tag values. All tags required to reach the final tag (at the end of the path) are created, if needed. Tags are created with default types (i.e. arrays will be ordered). Creating tags will fail if a prefix is encountered that has not been registered. Use [@link] CGImageMetadataRegisterNamespaceForPrefix @/link to associate a prefix with a namespace prior to using a path-based CGImageMetadata function.
    Examples
    - 'path' = CFSTR("xmp:CreateDate"), 'value' = CFSTR("2011-09-20T14:54:47-08:00")
    - 'path' = CFSTR("dc:subject[0]"), 'value' = CFSTR("San Francisco")
    - 'path' = CFSTR("dc:subject[1]"), 'value' = CFSTR("Golden Gate Bridge")
    - 'path' = CFSTR("dc:description[en]") 'value' = CFSTR("my image description")
    - 'path' = CFSTR("dc:description[de]") 'value' = CFSTR("meine bildbeschreibung")
    Note that if a parent tag is provided, the children of that tag reference will be modified, which may be a different reference from the tag stored in the metadata container. Since tags are normally obtained as a copy, it is typically neccesary to use CGImageMetadataSetTagWithPath to commit the changed parent object back to the metadata container (using the parent's path and NULL for the parent). [@link] CGImageMetadataCreateMutable @/link to obtain a mutable metadata container.
    Parameters:
    
    metadata - A mutable collection of metadata tags. Use @link CGImageMetadataCreateMutableCopy @/link or
    
    parent - A parent tag. If NULL, the path is relative to the root of the CGImageMetadataRef (i.e. it is not a child of another property).
    
    path - A string with the path to the desired tag. Please consult the documentation of @link CGImageMetadataCopyTagWithPath @/link for information about path syntax.
    
    value - The value to be added to the CGImageMetadataTag matching the path. The tag will be retained. The restrictions for the value are the same as in @link CGImageMetadataTagCreate @/link.
    
    Returns:
    
    Returns true if successful, false otherwise.

```
    [@function] CGImageMetadataRemoveTagWithPath
    Removes the tag at a specific path from a CGMutableImageMetadata container or from the parent tag
    Use this function to delete a metadata tag matching a specific path from a mutable metadata container. Note that if a parent tag is provided, the children of that tag reference will be modified, which may be a different reference from the tag stored in the metadata container. Since tags are normally obtained as a copy, it is typically neccesary to use CGImageMetadataSetTagWithPath to commit the changed parent object back to the metadata container (using the parent's path and NULL for the parent).
    
    Parameters:
    
    parent - A parent tag. If NULL, the path is relative to the root of the CGImageMetadataRef (i.e. it is not a child of another property).
    
    path - A string with the path to the desired tag. Please consult the documentation of @link CGImageMetadataCopyTagWithPath @/link for information about path syntax.

```
    [@function] CGImageMetadataEnumerateTagsUsingBlock
    Executes a given block using each tag in the metadata
    This function iterates over all of the tags in a CGImageMetadataRef, executing the block for each tag. The default behavior iterates over all top-level tags in the metadata. The path of the tag and the tag itself is passed to the block. The metadata cannot be modified inside the block - consider adding the tags of interest into another collection.
    
    Parameters:
    
    metadata - A collection of metadata tags.
    
    rootPath - Iteration will occur for all children of the tag matching the root path. Please refer to CGImageMetadataCopyTagWithPath for information about path syntax. If NULL or an empty string, the block will be executed for all top-level tags in the metadata container.
    
    options - A dictionary of options for iterating through the tags. Currently the only supported option is kCGImageMetadataEnumerateRecursively, which should be set to a CFBoolean.
    
    block - The block that is executed for each tag in metadata.

    *! @functiongroup Working with CGImageProperties [@function] CGImageMetadataCopyTagMatchingImageProperty
    Searches for a specific CGImageMetadataTag matching a kCGImageProperty constant
    Provides a bridge for values from CGImageCopyPropertiesAtIndex, simplifying access for properties defined in EXIF and IPTC standards, which have no notion of namespaces, prefixes, or XMP property types. Metadata Working Group guidance is factored into the mapping of CGImageProperties to XMP compatible CGImageMetadataTags. For example, kCGImagePropertyExifDateTimeOriginal will get the value of the corresponding XMP tag, which is photoshop:DateCreated. Note that property values will still be in their XMP forms, such as "YYYY-MM-DDThh:mm:ss" for DateTime, rather than the EXIF or IPTC DateTime formats.
    
    Parameters:
    
    metadata - A collection of metadata tags
    
    dictionaryName - the metadata subdictionary to which the image property belongs, such as kCGImagePropertyExifDictionary or kCGImagePropertyIPTCDictionary. Not all dictionaries and properties are supported at this time.
    
    propertyName - the name of the property. This must be a defined property constant corresponding to the 'dictionaryName'. For example, kCGImagePropertyTIFFOrientation, kCGImagePropertyExifDateTimeOriginal, or kCGImagePropertyIPTCKeywords. A warning will be logged if the CGImageProperty is unsupported by CGImageMetadata.
    
    Returns:
    
    Returns a CGImageMetadataTagRef with the appropriate namespace, prefix, tag name, and XMP value for the corresponding CGImageProperty. Returns NULL if the property could not be found.

public static boolean CGImageMetadataSetValueMatchingImageProperty(CGMutableImageMetadataRef metadata,
                                                                   CFStringRef dictionaryName,

```
    [@function] CGImageMetadataSetValueMatchingImageProperty
    Sets the value of the CGImageMetadataTag matching a kCGImageProperty constant
    Provides a bridge for values from CGImageCopyPropertiesAtIndex, simplifying changing property values defined in EXIF and IPTC standards, which have no notion of namespaces, prefixes, or XMP property types. Metadata Working Group guidance is factored into the mapping of CGImageProperties to XMP compatible CGImageMetadataTags. For example, setting kCGImagePropertyExifDateTimeOriginal will set the value of the corresponding XMP tag, which is photoshop:DateCreated. Note that property values should still be in their XMP forms, such as "YYYY-MM-DDThh:mm:ss" for DateTime, rather than the EXIF or IPTC DateTime formats. Although this function will allow the caller to set custom values for these properties, you should consult the appropriate specifications for details about property value formats for EXIF and IPTC tags in XMP.
    
    Parameters:
    
    metadata - A mutable collection of metadata tags
    
    dictionaryName - the metadata subdictionary to which the image property belongs, such as kCGImagePropertyExifDictionary or kCGImagePropertyIPTCDictionary. Not all dictionaries and properties are supported at this time.
    
    propertyName - the name of the property. This must be a defined property constant corresponding to the 'dictionaryName'. For example, kCGImagePropertyTIFFOrientation, kCGImagePropertyExifDateTimeOriginal, or kCGImagePropertyIPTCKeywords. A warning will be logged if the CGImageProperty is unsupported by CGImageMetadata.
    
    value - A CFTypeRef with the value for the tag. The same value restrictions apply as in @link CGImageMetadataTagCreate @/link.
    
    Returns:
    
    Returns true if successful, false otherwise.

    Parameters:
    
    metadata - A collection of metadata tags.
    
    options - should be NULL. Options are currently not used, but may be used in future release.
    
    Returns:
    
    Returns a CFData containing an XMP representation of the metadata. Returns NULL if an error occurred.

```
    Losslessly copies the contents of the image source, 'isrc', to the destination, 'idst'. The image data will not be modified. The image's metadata can be modified by adding the keys and values defined above to 'options'. No other images should be added to the image destination. CGImageDestinationFinalize() should not be called afterward - the result is saved to the destination when this function returns. The image type of the destination must match the image source. Returns true if the operation was successful. If an error occurs, false will be returned and 'err' will be set to a CFErrorRef. Not all image formats are supported for this operation.

  - kCGImageMetadataShouldExcludeGPS
```
public static CFStringRef kCGImageMetadataShouldExcludeGPS()
```
    If true, GPS metadata will not be written to EXIF data or the corresponding EXIF tags in XMP. This flag cannot filter any proprietary location data that could be stored in a manufacturer's EXIF MakerNote or custom XMP properties. If present, the value for this key is a CFBooleanRef. The default is kCFBooleanFalse.
  - kCGImageDestinationDateTime
