FileReferenceAssociationRelationship Property

The file's association relationship

This property is if the file is not associated with any object. When associating a file reference with an object such as the document or a page, then this property defines the relationship between the file and the object. Typical values are:

• "Source": used if this file is the original source material for the associated content.
• "Data": used if this file represents information used to derive a visual presentation such as for a table or a graph.
• "Alternative": used if this file is an alternative representation of content, for example audio.
• "Supplement": used if this file represents a supplemental representation of the original source or data that may be more easily consumable (e.g., a MathML version of an equation).
• "EncryptedPayload": used if this file is an encrypted payload document that should be displayed to the user if the PDF processor has the cryptographic filter needed to decrypt the document.
• "FormData": used if this file is the data associated with form fields of this PDF.
• "Schema": used if this file is a schema definition for the associated object.
• "Unspecified": used when the relationship is not known.
