PostScript files or PDF files (both for Windows and Linux) but I
haven't been successful in generating a file which is considered PDF/A

following minimal file (in LaTeX) via dvips:
=== file a.tex ===
\documentclass{article}
\begin{document}
Just this line...

The PDF/A Wikipedia page makes it look pretty straightforward -- all fonts
embedded, all fonts legal everywhere, no video, audio or javascript, device
independent color.
Maybe it's a font issue (the validator not knowing the CM latex fonts)?
How about trying the standard PS fonts, like
=== file a.tex ===
\documentclass{article}
\usepackage{mathptmx} % or \usepackage{mathpazo}
\begin{document}

The PDF/A Wikipedia page makes it look pretty straightforward -- all fonts

Maybe it's a font issue (the validator not knowing the CM latex fonts)?
How about trying the standard PS fonts, like

Hi Ernesto,
This isn't responsive to your question, but maybe, just maybe, it's responsive
to your situation.
I see nothing but heartache in PDF/A. PDF/A test notwithstanding, I contend
you don't REALLY know it it will render accurately (or at all) years from
now. Things happen.
Of all the ways to define data, PDF is one of the most complex. I've modified
PDFs with pdftk, and (ugh) with Vim. It's ugly, unless you know the whole
standard by heart. It's not human readable.
More to the point, over years and decades, standards come and go. Those QIC
tapes I so joyously used in 1994 are unreadable today unless I go out and buy
a QIC tape drive and somehow get the matching software. Do you really think
the ISO9660 standard so ubiquitous today will exist in 2050? Me neither. My
prediction -- .tgz and .zip will be the stuff of old-timer reminiscences by
then, the way Kaypro computers are today. And PDF, I doubt it will exist.
If something's really important to have throughout the ages, print it to nice,
acid free paper, and store it appropriately. That will last at least 200
years.
I called the US trademark office and asked whether I could submit my Ebooks'
copyright specimens on paper in addition to electronically on CD. They said
yes, they prefer it that way, because paper stands the test of time, and
digital representations don't necessarily.
I have handwritten journal pages from the mid 1970's, written in ballpoint pen
on cheap notebook paper, that are perfectly readable over 30 years later. I
dare you to read a magtape from 1975.
If you have a lot of docs that must be archived, and space is a concern,
perhaps microfiche is the way to go. I'd guess that will last at least 30
years, always assuming they keep making microfiche readers.
If you MUST go digital, I recommend plain text. In 1987, when I first started
making invoices for customers, I made a very savvy choice. All my invoices,
from 1987 through the present, have been plain text. Formatting was done by
inserting space characters. No tabs, which of course can be redefined by the
rendering software. If you absolutely must go digital with data meant to
survive a century, plain text is the way to do it. As long as ASCII exists
(or a codepage that maps to old ASCII), and as long as I keep copying those
invoices to media that can be read by newly current technologies, my invoices
will be readable.
Personally, when I hear the words PDF and archive in the same sentence, I
become very skeptical.

Re: Generating PDF/A from LyX/LaTeX

What does the university say about validators -- any validator, all
validators, Adobe's validator?
The PDF/A Wikipedia page makes it look pretty straightforward -- all fonts
embedded, all fonts legal everywhere, no video, audio or javascript, device
independent color.
Makes sense when thought about from a portability as opposed to a long term
archival viewpoint. And it seems straightforward, except for proving it :-)

As far as I know, the generated PDF includes all fonts, and since it's

no audio, no video, no javascript, not event hyperrefs.

yes, they prefer it that way, because paper stands the test of time, and
digital representations don't necessarily.
I have handwritten journal pages from the mid 1970's, written in ballpoint pen
on cheap notebook paper, that are perfectly readable over 30 years later. I
dare you to read a magtape from 1975.
If you have a lot of docs that must be archived, and space is a concern,
perhaps microfiche is the way to go. I'd guess that will last at least 30
years, always assuming they keep making microfiche readers.
If you MUST go digital, I recommend plain text. In 1987, when I first started
making invoices for customers, I made a very savvy choice. All my invoices,
from 1987 through the present, have been plain text. Formatting was done by
inserting space characters. No tabs, which of course can be redefined by the
rendering software. If you absolutely must go digital with data meant to
survive a century, plain text is the way to do it. As long as ASCII exists
(or a codepage that maps to old ASCII), and as long as I keep copying those
invoices to media that can be read by newly current technologies, my invoices
will be readable.
Personally, when I hear the words PDF and archive in the same sentence, I
become very skeptical.

Re: Generating PDF/A from LyX/LaTeX
Hi. I do not have a particular preference for PDF/A, but unfortunately

Hi Ernesto,
This isn't responsive to your question, but maybe, just maybe, it's responsive
to your situation.
I see nothing but heartache in PDF/A. PDF/A test notwithstanding, I contend
you don't REALLY know it it will render accurately (or at all) years from
now. Things happen.
Of all the ways to define data, PDF is one of the most complex. I've modified
PDFs with pdftk, and (ugh) with Vim. It's ugly, unless you know the whole
standard by heart. It's not human readable.
More to the point, over years and decades, standards come and go. Those QIC
tapes I so joyously used in 1994 are unreadable today unless I go out and buy
a QIC tape drive and somehow get the matching software. Do you really think
the ISO9660 standard so ubiquitous today will exist in 2050? Me neither. My
prediction -- .tgz and .zip will be the stuff of old-timer reminiscences by
then, the way Kaypro computers are today. And PDF, I doubt it will exist.
If something's really important to have throughout the ages, print it to nice,
acid free paper, and store it appropriately. That will last at least 200
years.
I called the US trademark office and asked whether I could submit my Ebooks'
copyright specimens on paper in addition to electronically on CD. They said
yes, they prefer it that way, because paper stands the test of time, and

Re: Generating PDF/A from LyX/LaTeX
What a nightmare!
What does the university say about validators -- any validator, all
validators, Adobe's validator?
The PDF/A Wikipedia page makes it look pretty straightforward -- all fonts
embedded, all fonts legal everywhere, no video, audio or javascript, device
independent color.
Makes sense when thought about from a portability as opposed to a long term
archival viewpoint. And it seems straightforward, except for proving it :-)

As far as I know, the generated PDF includes all fonts, and since it's

no audio, no video, no javascript, not event hyperrefs.

I have tried PDF/A-1b:2005(CMYK) and PDF/A-1b:2005(RGB), and preflight still complains. In particular it gives me an error "Width information for glyphs is inconsistent (1 match on 1 page)" I tried the conversion directly through Distiller and within Acrobat itself... > William > > -- > William Adams > senior graphic designer > Fry Communications > > > -- Ernesto Posse Applied Formal Methods Group - Software Technology Lab School of Computing Queen's University - Kingston, Ontario, Canada
Re: Generating PDF/A from LyX/LaTeX
What a nightmare!
What does the university say about validators -- any validator, all
validators, Adobe's validator?
The PDF/A Wikipedia page makes it look pretty straightforward -- all fonts
embedded, all fonts legal everywhere, no video, audio or javascript, device
independent color.
Makes sense when thought about from a portability as opposed to a long term
archival viewpoint. And it seems straightforward, except for proving it :-)

Indeed.

They use Acrobat's. It seems that Adobe's Distiller has its own
validator which is different than Acrobat's, since Distiller says the
generated file is compliant, but Acrobat says it is not.

As far as I know, the generated PDF includes all fonts, and since it's
that minimal latex file I mentioned, it does not have anything fancy,
no audio, no video, no javascript, not event hyperrefs.

Next step -- find a small PDF that the Acrobat validator says complies, and try to exploit the differences between that file and your timy LyX-derived PDF. Also this will tell you if your particular validator won't pass ANYTHING. SteveT
