Apparently, PDF is an open standard, that can be implemented by anyone in any piece of software. If this is the case, why do you have to purchase the standard from ISO? The standard is ISO/IEC 32000:1:2008. It seems to cost about $380 to download the Portable Document Format specification. It also seems that a lot of the specifications cost money. Why would an open standard like PDF cost money to download? And how do we get free implementations of a PDF reader and/or creator, if the specification costs money?

I considered that, but I thought that this might be more general than programming. – AniDev – 2010-10-12T22:06:44.270
