Associated Files (defined in ISO 32000-2, 14.13) leverage the ubiquity of PDF to build on the commonplace concept of “attachments” in electronic communications.
The Associated Files model is exceptionally flexible and can address a wide variety of use cases. Using the Associated Files feature, PDF 2.0 writers can provide additional information as files related to a PDF object in a standardized and therefore machine-readable and potentially machine-actionable way. The Associated Files mechanism also provides for connecting metadata about a related object with the related object itself.
