Hi, 

I'm advocating the use of PDF/A file formats at my company.

However, in the context of scanned documents with OCR, the benefits of PDF/A over PDF are unclear to me.   Does anyone have some thoughts to share on this matter.

Thanks,

Please find here some discussion related to variances in PDF/A.
Hope it can help.

What is the difference between PDF/A, A-1a, A-1b
PDF/A-1a ensures the preservation of a document’s logical structure and content text stream in natural reading order. The text extraction is especially important when the document must be displayed on a mobile device (for example a PDA) or other devices in accordance with Section 508 of the US Rehabilitation Act. In such cases the text must be reorganized on the limited screen size (re-flow). This feature is also known as “Tagged PDFs”.
PDF/A-1b ensures that the text (and additional content) can be correctly displayed (e.g. on a computer monitor), but does not guarantee that extracted text will be legible or comprehensible. It therefore does not guarantee compliance with Section 508.
The difference between PDF/A-1a and -1b has no impact for scanned documents, provided the files have not been enhanced by means of OCR for searching.
