The specification of Adobe PDF is proprietary but available at 
The PDF 1.5 spec is a "mere" 1149 pages long; I haven't checked the
current version (1.6).
The specification for Macromedia Flash (or should I now way Adobe Flash?)
can be downloaded when you agree to a license agreement 
(at http://www.macromedia.com/software/flash/open/licensing/fileformat/license2.html)
that says you can "use the Specification for the sole purposes of developing
Products that output SWF" (i.e. not for developing products that check for
accessibility problems??).
An ActionScript Language Reference can be downloaded from
http://www.macromedia.com/support/documentation/en/flash/, but I 
think this is less useful for our purposes.
