Before PDF: John Warnock's 'Camelot'

Karl De Abrew writes: "In the Spring of 1991 Dr. John Warnock wrote a paper he dubbed "Camelot" in which the Adobe Systems Co-founder and CEO laid out the foundation for what has become Acrobat/PDF. With the author's permission, Planet PDF is pleased to publish the full-text of that historic document." Of course, now it's 2002, and the dream of universal display / printing remains only partly realized; PDFs really have helped to narrow the gap between dream and reality, though.

Profound.

Especially when you consider that OSX now has a graphics engine based on PDF, which begins to finally close the gap between screen and paper ...

Gotta love those dreamy nerds.

First you have to understand that PDF is designed as a page description language (with some add-ons for forms and scripts), while Microsoft word is a word processor. Those are different tools.

Also while the pdf format is controlled by Adobe, the specs are open and available (contrast this with Microsoft's format which is a complete mystery), you can get the specs from Adobe's site and nothing prevents you from writing code that manipulates pdf files (well yes there are issues with compression algorithm).

This openess is the reason why Apple chose to use pdf as their graphic description language for OS X (older OS versions used QuickDraw). The windows page description language, is, I think, WMF. It's funny to think that the basic page description language used under Unix is Postscript, which is much more closed than PDF.

Acrobat Pro allows you to edit PDFs, and with Ghostscript, you can edit PDFs and strip the "security" from encrypted PDFs leaving you with the original, 100% editable file.

PDFs are editable, you just need the right tools.
