Definition: PDF/A-3, standardised as ISO 19005-3, is an ISO standard for long-term archiving of electronic documents in PDF form that additionally permits embedding arbitrary file formats (e.g. XML or structured data) within the PDF container, used where a human-readable document must carry an embedded machine-readable payload.

Interoperability Saliency: Salient for technical interoperability because it standardises how a long-term-archivable, human-readable clinical document can also carry an embedded machine-readable structured payload for downstream processing.
