Enum Relationship 

pub enum Relationship {
    Source,
    Data,
    Alternative,
    Supplement,
    EncryptedPayload,
    FormData,
    Schema,
    Unspecified,
}

What an associated file is to the thing it is associated with (/AFRelationship, ISO 32000-2 table 404).

The relationship is not decoration: a PDF/A-3 validator reads it, and an electronic-invoice profile requires the invoice XML to be Alternative — the machine-readable form of what the page shows — rather than Supplement or Unspecified.

Variants

Source

/Source: the file the visible content was generated from.

Data

/Data: data the content presents — a spreadsheet behind a chart.

Alternative

/Alternative: an alternative representation of the same content. This is what an electronic invoice’s XML is.

Supplement

/Supplement: additional material the content does not itself show.

EncryptedPayload

/EncryptedPayload: the file is an encrypted payload, and the document around it is the wrapper.

FormData

/FormData: the data of a form the document presents.

Schema

/Schema: a schema the associated data conforms to.

Unspecified

/Unspecified: the relationship is not stated. The default, and what a validator that requires one will reject.
