Open Source PDF/A RDF Schemas

Inspired by the Isartor test set for validating PDF/A compliance we are working on a similar style set of negative tests for basic XMP compliance (PDF/A XMP TechNotes).

While it is clear that this work needs to be done, nobody appears to be tackling it. PDF/A 19005-1 is now heading into its 3rd year so we're attempting to fill this gap.

While each vendor will obviously implement their own XMP validator for PDF/A validation and conversion, there are some areas where we can easily collaborate. We believe that it is in all our interests to openly share an RDF and PDF/A compliant XMP implementation of the pre-defined schemas required to validate PDF/A files.

Today we released our first version of the PDF/A pre-defined schemas in RDF form. You can find these resources at the PDF/D website.
