pdf - COS代表什么？

Question

我一直在向自己介绍 PDF 文件结构，并且一直在阅读以下内容:

The Adobe PDF 32000-1:2008 Reference

IDR Solutions Blog

GNU Introduction to PDF

然后我遇到了以下产品:

COS Level Editor for PDF

PDF 'COS level' CanOpener

“显示和编辑 PDF 文件的内部 COS(对象)结构”。

尽管很明显 COS 对象是什么(参见 PDF 规范的第 7.3 节)，但我找不到任何关于 COS 是什么首字母缩写词的引用或解释。

有谁知道与 PDF 相关的 COS 这个词是从哪里来的？

Answer 1

如 jonrsharpe在他的评论中提到， COS 代表 轮播对象系统 ，但要解释更多...

来自 In Defense of COS, or Why I Love JSON and Hate XML :

My good friend Richard Cohen introduced the Carousel Object Structure when he introduced the PDF file format back in 1993 (Carousel was the project birth name for Adobe Acrobat).

理查德·科恩 (Richard Cohen) 然后添加了评论:

I'm afraid to add too many names as contributors because of the risk of leaving people out, but I will note that the basic PDF syntax that Jim describes was taken directly from PostScript, so give John Warnock and the original PostScript team credit there. There were a couple of attempts at a format for Carousel before what we have now, but Alan Wootton and I came up with the core of what became PDF 1.0 in a few days at my house in April 1992.

来自 Chapter 1 of Developing with PDF :

COS stands for Carousel Object System and refers to the original/code name for Adobe’s Acrobat product.

来自 What-When-How :

Although Carousel was only a code name for what later became Acrobat, the name is still used to refer to the way a PDF file is composed

来自 Wikipedia :

The format is a subset of a COS ("Carousel" Object Structure) format.
