I support individuals who on occasion have to submit a mass of files to a court and the requirement is that the files be in PDF/A format. Most are scanned files lacking the requisite structure to become PDF/A-1a files. So as I convert or resave files, I need to be able to specify that they be converted to the PDF/A-1b standard. And since it may involve over 100 files, it would be very inefficient to do so individually, file by file. Could this be done via an Action Wizard sequence? Could a script be written in Java that go through such a process, specifically choosing a PDF/A standard? Any insights would be appreciated.
Proper pdf/a can't be automated; it requires detailed page at a time validation by a skilled human.
PDF/A-1a is very easy to automate in Acrobat XI Pro, indeed the compliance code was rewritten specifically with this in mind. Test Screen Name is correct that PDF/A-1b can't be realistically automated due to the complexity of tagging, but that's not your concern.
Files with security, distributed forms, etc. can't be converted but the Acrobat engineering team claim that everything which can possibly be shoehorned into PDF/A will always succeed. In previous versions of Acrobat it often failed when it encountered things like iffy XMP data.
