I agree with you -- from the point of view of architecture, why
should PDF be a special case.
But consider my point of view as an information provider. Suppose I
have a book that contains text and drawings. I'd like to distribute a
hypertext version of the book. I'd like to know that the format I
pick for my drawings can be read by most (or all) WWW browsers. PDF
might be that format, for the reasons I outlined earlier. Is there a
better format to use as a default?
Furthermore, as an information provider, I want to distribute only
one version of my book. I can distribute a single PDF file with
assurance that any Mac or Windows user can read the document (and DOS
and UNIX users too, when Adobe achieves its promises). (This begs the
question, "will Acrobat catch on" -- but anyone can buy an Acrobat
reader in an Egghead Software store for $40 and I'm willing to take
Suppose the first page of the book said...
"If you have a WWW browser and an Internet connection, click here for
a more current version of this book (across the net). If you are
using an Adobe PDF reader, click here to learn more about WWW and the
Internet (information in this local file)."
If the PDF link annotation were extended to accomodate URL/URNs, and
the user's WWW browser read PDF files, the user could bounce to a
newer (and structured) HTML version of the book. If they can't, well,
I'm still assured they can read the version they've got and maybe
they'll get web-happy later.
As an information provider, I want to be assured the format of the
files I distribute can be read by as many people as possible. I'm not
going to be distributing the majority of my books across the net
(that would limit my market for now). But I'd like to offer the
advantages of the Web's Internet hyperlinks to readers who can use
them. Of course, PDF ability doesn't have to built into every WWW
browser for this. I can hope some WWW browsers are installed with PDF
viewers as linked applications. But that still leaves me with the
problem of not knowing if I've picked a format that can read by most
WWW users. So I'd prefer to see native support for PDF in WWW
Of course, we need to recognize that this is wildly speculative right
now. I don't know that a WWW browser can accomodate PDF and I don't
know that Adobe would accept a proposal to extend the PDF link
annotation specification. But it's worth exploring.
