RiffInfoPackage class

Represents the metadata package containing properties extracted from the RIFF INFO chunk.

Inheritance: RiffInfoPackage → CustomPackage → MetadataPackage

The RiffInfoPackage type exposes the following members:

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.
artist	Gets the artist of the original subject of the file.
comment	Gets the comment about the file or the subject of the file.
copyright	Gets the copyright information for the file.
creation_date	Gets the date the subject of the file was created.
engineer	Gets the name of the engineer who worked on the file.
genre	Gets the genre of the original work.
keywords	Gets the keywords that refer to the file or subject of the file.
name	Gets the title of the subject of the file.
subject	Gets a description of the file contents, such as “Aerial view of Seattle.”
software	Gets the name of the software package used to create the file.
source	Gets the name of the person or organization who supplied the original subject of the file.
technician	Gets the technician who digitized the subject file.

Method	Description
`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.
