thammond – 2007 August 23
Following on from yesterday’s post I just came across this very useful source of information on PDF/A: the PDF/A Conformance Center. This provides links to resources such as this whitepaper PDF/A - A new Standard for Long-Term Archiving, and a number of technical notes, especially Metadata and PDF/A-1(also available as a PDF). (This latter corrects some errors in the ISO standard which are to be redressed in a forthcoming Technical Corrigendum later this year.)
Still difficult to find examples of PDF/A though (the discussion forum doesn’t throw up too much on that score) although at least the Technical Note linked to above is a PDF/A-1 document as can be seen from this XMP description:
<rdf:Description rdf:about="" xmlns:pdfaid="http://www.aiim.org/pdfa/ns/id/"> <pdfaid:part>1</pdfaid:part> <pdfaid:conformance>A</pdfaid:conformance> </rdf:Description>
As noted before, PDF/A may be more (and less) than Crossref publishers require at this time, but nonetheless it is certainly a useful yardstick as regards embedding metadata within a PDF and is anyway a technology worth tracking in its own right.
