Is there a way that I can know the date of a PDF file being created and uploaded?
I was there for the whole thing. It was the 90's and Create Fillable Form was doing well. In addition to the Systems department which handled the Postscript business there was an Applications group which had Photoshop and Illustrator. John Warnock had the idea that every document that was ever printed, or ever would be printed, could be represented in a document. This was not an unreasonable idea since Postscript was designed for this purpose and Create Fillable Form also had some code from Illustrator that would handle the fonts and graphics and code from Photoshop to display images. So, Warnok started a project (the Carousel project) on his own initiative to pursue his idea that eventually the whole Library of Congress could be represented in an archival electronic format. In the beginning he could only get part time help from programmers in the applications division - Mike Pell, Ken Grant, Mike Diamond. The project was progressing slowly so the head of the division (Eric Zocker?) started a search for a new programmer to handle the project full time. Alan Tracey Wootton had transitioned from programming at JPL to full time programming and was looking to leave LA and be more professional in Silicon Valley. He got the job and moved to Cupertino. Soon there was a demo and then a team developed to produce UI for the various platforms - Mac, Windows, DOS, and 'nix. The demo code progressed into cross-platform code to handle most of the internal data structures to support the UI projects. There were also people writing print-drivers to create documents through the printing process on all platforms. By this point the original demos were re-written into a file format that would contain the fonts, vector graphics, and images - this would be the second file format for the project. However, there were requirements that were not being met. Requirements like forward and backwards compatibility, streaming large documents through a printer driver where the printer driver has no idea how many pages there will be, and opening a 1000 page document and being able to jump directly to the 500th page without reading the whole file. Peter Hibberd had written a demo of an 'object oriented file format' so Richard Cohn and Alan Wootton went to work trying to adapt his work for use on the Carousel project. After many weeks of struggle it was decided that adapting his work was going to be more work than writing new code and that some of the 'object oriented' concepts were not applicable since it was finally becoming obvious that a key-value format was going to be part of the solution. This was the third file format. Bob Wulff, the manager of the project, told Richard and Alan to 'go away' and to not come back until there was a file format! The next Monday Richard and Alan started meeting at Richard's house in Menlo Park instead of going to work in Mountain View (where Google is now). By the end of Thursday, Richard and Alan had described data structures and concepts for a file format on many pieces of paper. Alan went home, pulled 4 overnights in a row and came back to Create Fillable Form on Monday with the fourth file format written and working in the current code. This file format became known as PDF.
Create PDF: All You Need to Know
The PDF is a superset of the HTML that used to be used for the HTML2 documents that ran on the Windows platform. But the PDF is different in many respects. While being different from HTML, it was designed to have most of the qualities that you find in a native software product — features that could be put into HTML. At this point the Carousel/Carousel-on-Windows project was moving forward so much that it became really obvious that the Carousel/PDF/carousel-on-Windows team had so much to learn from the other Carousel/PDF/carousel-on-Windows groups that they could start out by copying some of the same ideas. The Carousel-on-Windows Group started out copying some ideas from the Carousel/Carousel-on-MacOS project. They got started by using the X11 graphics system that came in X.org as an example of how it worked. The Carousel-on-MacOS project was starting to go very well and the Carousel/Carousel-on-Windows and Carousel/macOS project.
