XmpPackage class

Represents base abstraction for XMP package.

Inheritance: XmpPackage → XmpMetadataContainer → CustomPackage → MetadataPackage

The XmpPackage type exposes the following members:

Constructors

Constructor	Description
`__init__(self, prefix, namespace_uri)`	Initializes a new instance of the `XmpPackage` class.

Properties

Property	Description
metadata_type	Gets the metadata type.
keys	Gets a collection of the metadata property names.
property_descriptors	Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
count	Gets the number of metadata properties.
prefix	Gets the xmlns prefix.
namespace_uri	Gets the namespace URI.
xml_namespace	Gets the XML namespace.

Methods

Method	Description
`set(self, name, value)`	Sets string property.
`set(self, name, value)`	Sets integer property.
`set(self, name, value)`	Sets boolean property.
`set(self, name, value)`	Sets DateTime property.
`set(self, name, value)`	Sets double property.
`set(self, name, value)`	Sets the value inherited from `XmpValueBase` .
`set(self, name, value)`	Sets the value inherited from `XmpComplexType` .
`set(self, name, value)`	Sets the value inherited from `XmpArray` .
`contains(self, property_name)`	Determines whether the package contains a metadata property with the specified name.
`find_properties(self, specification)`	Finds the metadata properties satisfying a specification. The search is recursive so it affects all nested packages as well.
`update_properties(self, specification, value)`	Updates known metadata properties satisfying a specification. The operation is recursive so it affects all nested packages as well.
`remove_properties(self, specification)`	Removes metadata properties satisfying a specification.
`add_properties(self, specification, value)`	Adds known metadata properties satisfying the specification. The operation is recursive so it affects all nested packages as well.
`set_properties(self, specification, value)`	Sets known metadata properties satisfying the specification. The operation is recursive so it affects all nested packages as well. This method is a combination of `MetadataPackage.add_properties` and `MetadataPackage.update_properties`. If an existing property satisfies the specification its value is updated. If there is a known property missing in the package that satisfies the specification it is added to the package.
`sanitize(self)`	Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
`get_xmp_representation(self)`	Converts the XMP value to the XML representation.
`remove(self, name)`	Removes the property with the specified name.
`clear(self)`	Removes all XMP properties.
