Hi Les
I'm with Falk on this one.
Rather than "we should continue making PDFs open access with all our
energy" I would argue that we should ensure that papers are made available
in open formats (such XHTML) wherever possible, and regard PDFs as a tainted
compromise (although the ISO PDF-A format can be useful as a preservation
standard).
As well as the technical and interoperability benefits that open and
Web-native formats can provide, there is also a need (indeed, legal
requirement) to address issues such as accessibility. Indeed you touch on
this in your comment:
""True Open Access" is a hitherto unidentified specialisation of "Open
Access". The latter simply requires research outputs to be accessible to
everyone, without let or hindrance, now or in the future." "Without let or
hindrance" surely included access to people with disabilities?
The WAI WCAG guidelines state:
3.2 Create documents that validate to published formal grammars. [Priority
2]
11.1 Use W3C technologies when they are available and appropriate for a task
and use the latest versions when supported. [Priority 2]
11.4 If, after best efforts, you cannot create an accessible page, provide a
link to an alternative page that uses W3C technologies, is accessible, has
equivalent information (or functionality), and is updated as often as the
inaccessible (original) page. [Priority 1]
http://www.w3.org/TR/WAI-WEBCONTENT/
This doesn't seem very PDF-friendly.
Note that although WAI compliance is a legal requirement in various contexts
I (and others) have argued that the WAI model and WCAG guidelines have
fundamental flaws (and UK legislation, unlike that in other countries,
provides us with some degree of flexibility - we need to take reasonable
measures to ensure people with disabilities aren't discriminated against
unfairly, whereas legislation on other countries mandates WCAG compliance).
Our most recent papers are:

<http://www.ukoln.ac.uk/web-focus/papers/w4a-2005/>
Our approach (which, in part, is being addressed in the WCAG 2.0 guidelines)
argues that WAI should be neutral about technologies, as proprietary formats
(such as PDF, Flash, MS Word, etc.) can be accessible. However there is
still a need to ensure that the formats ARE accessible - and it is not clear
to me how the workflow processes will ensure that PDFs will contain ALT text
for images and the structural information needed for assistive technologies
to work correctly.
Surely if institutions need to handcraft PDFs in order to comply with
accessibility guidelines, it would be a more effective use of resources to
do this on the open format? Or perhaps I've missed these 'easy to use
tools' you refer to.

"True Open Access" is a hitherto unidentified
specialisation of "Open Access". The latter simply requires research outputs

future.
Perhaps you are suggesting that PDFs are not an optimal information
exchange vehicle - and many people (data miners) would agree with you.
However, PDF files are the majority means of dissemination, and while we
await the Next Great interoperability format (presumably based on XML)
together with the easy-to-use tools to go with it, we should continue making
PDFs open access with all our energy.
