PDBHeader class

Represents metadata in a Mobi e-book.

Inheritance: PDBHeader → CustomPackage → MetadataPackage

The PDBHeader 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.
name	Gets the Mobi e-book name.
attributes	Gets the mobi attributes.
version	Gets the Mobi version.
creation_date	Gets the creation date.
modification_date	Gets the modification date.
last_backup_date	Gets the last backup date.
modification_number	Gets the modification number.
app_info_id	Gets the app info ID.
sort_info_id	Gets the sort info ID.
type	Gets the type.
creator	Gets the creator.
unique_id_seed	Gets the unique ID seed.
next_record_list
num_records	Gets the num records.

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.
