Subject PDF/A validation
Date Wed, 27 Oct 2010 12:40:03 GMT

http://www.validatepdfa.com/ http://www.validatepdfa.com/ 

The above website allows you to send in pdf files (attached to an e-mail),
returning you a - rather detailed - report about the pdf/A conformity. In my
experience the report could easily inform you of errors and inform you of
not passing the conformity tests, while opening the same pdf file in Acrobat
Reader indicates the file is PDF/A conform.

I thought this could help out FOP users who wish to create PDF/A but don't
have the means of testing the conformity. I know it's been helpful in my
recent project and I saw some posts in the last few weeks about it.

It might even be helpfull to the Apache FOP developers. Though Acrobat
Reader indicated a file I created with FOP 1.0 as being conform, the
validation service still mentioned failure and following issues:

  problem severity="warning" objectID="8" clause="p32" standard="xmp">XMP
packet read-only

  problem severity="warning" objectID="8" clause="p33"
standard="xmp">Recommended padding is not found in the XMP packet trailer

  problem severity="error" objectID="8" clause="6.7"
standard="pdfa">Property 'dc:date' used incorrect value type 'simple'
instead of 'rdf:Seq'

  problem severity="warning" objectID="8" clause="TN0001"
standard="pdfa">Recommended property 'format' for schema 'dc' missing

Possibly other validators like preflight and pdf/a manager will also stumble
over these issues, while Acrobat Reader is less strict.

I hope this helps some people in their projects.
