To my way of thinking, the ability to search multiple pdf files for textual information contained within the drawing title block would be a major benefit. If you have a CD archive of several thousand drawings in pdf format, generally you can only search them by their filename. Within Google you can search for pdf's and find text information within the files. I understand that these pdfs were not created from CAD files and that CAD files would probably have to be OCR'd to get this kind of functionality. But perhaps this functionality exists now. Can you set me straight as to what CAD archiving functionality already exists with the latest versions of Acrobat ? Best Regards Adrian Dunevein www.aaadrafting.com Dear Leonard;

Within Google you can search for pdf’s and find text information within the files. I understand that these pdfs were not created from CAD files and that CAD files would probably have to be OCR’d to get this kind of functionality.

But perhaps this functionality exists now. Can you set me straight as to what CAD archiving functionality already exists with the latest versions of Acrobat ?

This gives a clear overview of what is out there, at least for me who is in learnig mode. He mentioned that there would be a link to the presentations he did on this site. Where could I find the links to his presntations (also the pdf internals). Regarding standards Leonard did a good presentation at the Pdf conference.

Let's look at each one. >Tools to display PDF/A Well, since PDF/A is a subset of PDF 1.4, the answer is A LOT! I would that pretty much every PDF viewer out there - from open source (Xpdf, Ghostscript, Kpdf, etc.) to commercial (FoxIt, Jaws, etc.) HOWEVER, it should be noted that ONLY Acrobat/Reader 8 actually adhere to all the requirements of a PDF/A compliant viewer.

>Tools to display PDF/A

Well, since PDF/A is a subset of PDF 1.4, the answer is A LOT! I would that pretty much every PDF viewer out there - from open source (Xpdf, Ghostscript, Kpdf, etc.) to commercial (FoxIt, Jaws, etc.) HOWEVER, it should be noted that ONLY Acrobat/Reader 8 actually adhere to all the requirements of a PDF/A compliant viewer.

But taking that to the other products.
>Tools to display ODF or OOXML

Other than OpenOffice and Office 2007 - I am not aware of any :( .

>How close is PDF/A to the “original”

If it’s not a 100% faithful visual representation - then whatever created the PDF/A document should be publicly flogged. Seriously, the whole point of PDF (and by reference, PDF/A) is reliable visual reproduction. But again, you have a better chance of the PDF being 100% faithful than trying to render the same ODF/OOXML on a completely different computer.

>Is it important to save visual appearance vs. content & structure

As I noted above - to the archivists, the answer is a resounding YES! Why, because what the HUMAN saw when they authored it was the visual appearance and NOT the “computer representation of content & structure”. Therefore, future humans MUST see the same thing the author saw.

But again, perhaps what you are trying to achieve is about data and not visual - and that’s fine. PDF/A is NOT a solution for everything..

How many tools are able to display a PDF/A with all possible features? How close is the converted PDF/A file to the “original”? Is it really important to save the visible appearance instead of saving the content structure and well known formating instructions? Both formats are not perfect in doing the archive job...
