Technical Note 0003 – Metadata in PDF/A-1

PDF/A-1 imposes certain requirements and restrictions on document metadata in a compliant PDF/A-1 file where certain information is required to be encoded as XMP metadata, while corresponding entries in the document information dictionary for a document may be present but must match information present in the document’s XMP-encoded metadata.

Note:  Due to an oversight before the publication of ISO 19005-1 the provisions regarding XMP metadata and document information entries were not worded correctly. This is addressed by Technical Corrigendum 1 which was released by ISO in April 2007. The explanations offered in this TechNote are based on the PDF/A-1 publication.
