This collection includes both standard document metadata and any custom metadata specified via CustomMetadata during import.

Standard metadata keys include:

• Document ID (accessed via Id)
• Document name (accessed via Name)

Use this property to access custom metadata fields added during document import, such as author, category, version, or any domain-specific attributes.
