The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. In 1991, Adobe Systems' co-founder John Warnock outlined a system called "Camelot" that developed into PDF.
Adobe Systems made the PDF specification available free of charge in 1993. PDF was a proprietary format controlled by Adobe, until it was officially released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO 32000-1:2008, at which time control of the specification passed to an ISO Committee of volunteer industry experts. In 2008, Adobe published a Public Patent License to ISO 32000-1 granting royalty-free rights for all patents owned by Adobe that are necessary to make, use, sell, and distribute PDF compliant implementations. However, there are still some proprietary technologies defined only by Adobe, such as Adobe XML Forms Architecture and JavaScript for Acrobat, which are referenced by ISO 32000-1 as normative and indispensable for the application of the ISO 32000-1 specification. These proprietary technologies are not standardized and their specification is published only on Adobe’s website. The ISO committee is actively standardizing many of these as part of ISO 32000-2.
Im turning my safety off
Im ready to talk to you
Alone
A kiss, a hug, another drink
Puts me right back to
Denial of persistent memory
Im watching you
Make a fool of you
Over and over again
You can leave the fire open
Its not dying anyway
Its not dying anyway
Its not dying anyway
Im turning my safety off
Unclasping my guarded moments
For you
Nothing here is apropos
And Im crying out to saints and sinners alike
Im giving you all the soul Ive got
Again and again and again
You can leave the fire open
Its not dying anyway
Its not dying anyway
Its not dying anyway
You can leave the memory open
Its not dying anyway
Its not dying anyway
Its not dying anyway
Im turning my safety off
Im ready to fall in love with you
