The XmpPacketWrapper type exposes the following members:

Constructors

Constructor	Description
init	Initializes a new XmpPacketWrapper instance.
init	Initializes a new instance of the `XmpPacketWrapper` class.

Methods

Method	Description
add_package	Adds the package.
add_package_xmp_package
clear_packages	Removes all `XmpPackage` inside XMP.
contains_package	Determines whether a package exists in the XMP wrapper.
contains_package_file
contains_package_string
get_package	Gets the package by namespace URI.
get_package_file
get_package_string
get_xmp_representation	Returns the XMP representation as a string.
remove_package	Removes the specified package.
remove_package_xmp_package
add_properties	Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. (inherited from `MetadataPackage`)
add_properties_func	(inherited from `MetadataPackage`)
contains	Returns True if the package contains a metadata property with the specified name; otherwise, False. (inherited from `MetadataPackage`)
contains_file	(inherited from `MetadataPackage`)
contains_string	(inherited from `MetadataPackage`)
find_properties	Finds metadata properties that satisfy the specified predicate, searching recursively through all nested packages. (inherited from `MetadataPackage`)
find_properties_func	(inherited from `MetadataPackage`)
get	(inherited from `MetadataPackage`)
get_enumerator	Returns an enumerator that iterates through the collection. (inherited from `MetadataPackage`)
get_file	(inherited from `MetadataPackage`)
get_string	(inherited from `MetadataPackage`)
remove_properties	Removes metadata properties satisfying the specified predicate. (inherited from `MetadataPackage`)
remove_properties_func	(inherited from `MetadataPackage`)
sanitize	Removes writable metadata properties from the package, recursively affecting all nested packages. (inherited from `MetadataPackage`)
set_properties	Sets known metadata properties satisfying the specified predicate. (inherited from `MetadataPackage`)
set_properties_func	(inherited from `MetadataPackage`)
update_properties	Updates known metadata properties that satisfy the specified predicate, recursively affecting all nested packages. (inherited from `MetadataPackage`)
update_properties_func	(inherited from `MetadataPackage`)

Properties

Property	Description
header_pi	The header processing instruction.
meta	The XMP meta.
package_count	The number of packages inside the XMP structure.
packages	The XMP packages contained in the packet.
schemes	The XMP schemes. Provides access to known XMP schemas.
trailer_pi	The trailer processing instruction.
count	The number of metadata properties. (inherited from `MetadataPackage`)
keys	The collection of metadata property names. (inherited from `MetadataPackage`)
know_property_descriptors	The collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine. (inherited from `MetadataPackage`)
metadata_type	The metadata type of the package. (inherited from `MetadataPackage`)
property_descriptors	The collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine. (inherited from `MetadataPackage`)

Example

from datetime import date
from groupdocs.metadata import Metadata
from groupdocs.metadata.standards.xmp import XmpArray, XmpArrayType, XmpPackage, XmpPacketWrapper

with Metadata("input.jpg") as metadata:
    root = metadata.get_root_package()
    packet = XmpPacketWrapper()
    custom = XmpPackage("gd", "https://groupdocs.com")
    custom.set("gd:Copyright", "Copyright (C) 2026 GroupDocs. All Rights Reserved.")
    custom.set("gd:CreationDate", date.today())
    custom.set(
        "gd:Company",
        XmpArray.from_(["Aspose", "GroupDocs"], XmpArrayType.ORDERED)
    )
    packet.add_package(custom)
    root.xmp_package = packet
    metadata.save("output.jpg")
