Posted by admin on May 15th, 2012 Specialized subsets of PDF
The following specialized subsets of PDF specification has been standardized as ISO standards (or are in standardization process):[1][18][19][20]
PDF/X (since 2001 – series of ISO 15929 and ISO 15930 standards) – a.k.a. “PDF for Exchange” – for the Graphic technology – Prepress digital data exchange – (working in ISO Technical committee 130), based on PDF 1.3, PDF 1.4 and later also PDF 1.6
PDF/A (since 2005 – series of ISO 19005 standards) – a.k.a. “PDF for Archive” – Document management – Electronic document file format for long-term preservation (working in ISO Technical committee 171), based on PDF 1.4 and later also ISO 32000-1 – PDF 1.7
PDF/E (since 2008 – ISO 24517) – a.k.a. “PDF for Engineering” – Document management – Engineering document format using PDF (working in ISO Technical committee 171), based on PDF 1.6
PDF/VT (since 2010 – ISO 16612-2) – a.k.a. “PDF for exchange of variable data and transactional (VT) printing” – Graphic technology – Variable data exchange (working in ISO Technical committee 130), based on PDF 1.6 as restricted by PDF/X-4 and PDF/X-5[21]
PDF/UA (under development in 2011 – ISO/DIS 14289-1) – a.k.a. “PDF for Universal Access” – Document management applications – Electronic document file format enhancement for accessibility (working in ISO Technical committee 171), based on ISO 32000-1 – PDF 1.7
There is also the PDF/H, a.k.a. “PDF Healthcare”, a Best Practices Guide (BPG), supplemented by an Implementation Guide (IG), published in 2008. PDF Healthcare is not a standard or proposed standard, but only a guide for use with existing standards and other technologies. It is supported by the standards development organizations ASTM and AIIM. PDF/H BPG is based on PDF 1.6.[22][23][24]
Full function PDF
PDF 1.7
The final revised documentation for PDF 1.7 was approved by ISO Technical Committee 171 in January 2008 and published as ISO 32000-1:2008 on July 1, 2008. PDF is now a published ISO standard, titled Document management—Portable document format—Part 1: PDF 1.7.
ISO 32000-1:2008 is the first ISO standard for the full function PDF. The previous ISO PDF standards (PDF/A, PDF/X, etc.) are for more specialized uses. The ISO 32000-1 includes all of the functionality previously documented in the Adobe PDF Specifications for versions 1.0 through 1.6. Adobe removed certain features of PDF from previous versions; these features are not contained in PDF 1.7 either.[1]
ISO 32000 document was prepared by Adobe Systems Incorporated based upon PDF Reference, sixth edition, Adobe Portable Document Format version 1.7, November 2006. It was reviewed, edited and adopted, under a special fast-track procedure, by ISO Technical Committee 171 (ISO/TC 171), Document management application, Subcommittee SC 2, Application issues, in parallel with its approval by the ISO member bodies.
According to the ISO PDF standard abstract:[25]
ISO 32000-1:2008 specifies a digital form for representing electronic documents to enable users to exchange and view electronic documents independent of the environment in which they were created or the environment in which they are viewed or printed. It is intended for the developer of software that creates PDF files (conforming writers), software that reads existing PDF files and interprets their contents for display and interaction (conforming readers) and PDF products that read and/or write PDF files for a variety of other purposes (conforming products).
PDF 2.0
A new version of PDF standard is under development under the name ISO/CD 32000-2 – Document management—Portable document format—Part 2: PDF 2.0 (as of July 2011).[26] PDF 2.0 was accepted by ISO as a new proposal in 2009 (ISO/NP 32000-2). Adobe has submitted the Adobe Extension Level 5 and Adobe Extension Level 3 specifications to ISO for inclusion into the next version of the ISO 32000 specification. Adobe declared they have all been accepted for part 2 of ISO 32000.[10]
