• PDF/A is all about electronic or born digital documents –this is how the standard defines electronic documents
“Electronic representation of a page-oriented aggregation of text and graphic data, and metadata useful to identify, understand and render that data,
that can be reproduced on paper or optical microform without significant loss of its information content. ”

Definition of Long-term
Long-term:
“period of time long enough for there to be concern about the impacts of changing technologies, including support for new media and data formats, and of a changing user community, on the information being held in a repository, which may extend into the indefinite future”
Source: ISO 19005-1
Long-term is important to PDF/A, this is how we define long-term:

Electronic Document Types
• TIFF▫ Well known▫ Difficult to create digitally born documents▫ Indexing documents may be difficult▫ Access is through an index
![Page 10: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/10.jpg)
Electronic Document Types
• XML▫ Many schema exist▫ Preserves content not the structure▫ Depends on DTD for visual appearance
![Page 11: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/11.jpg)
Electronic Document Types
• Native File Formats▫ Several file formats (.doc, .docx, .wpd, .rtf, .xls) ▫ May render differently depending on the device or
platform used▫ May be proprietary
![Page 12: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/12.jpg)
PDF• Portable Document Format▫ Widely used world wide Business Government Libraries and archives
▫ Information must be kept for long periods of time▫ Must remain useable and accessible across multiple
generations of technology

What is PDF?
• Reliable consistent viewing and printing• Mix text, raster images, line art, color• Basic unit is the page• Easy navigation, fast access to any page• Small file size
![Page 14: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/14.jpg)
Why Standardize a Version of PDF
• PDF is powerful and flexible• May be too flexible for some applications• Need higher degree of reliability • May want standard in hands of neutral non-commercial
body
![Page 15: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/15.jpg)
PDF/A: The Standard
ISO 19005-1:2005, Document management – Electronic document file format for long-term preservation – Part 1: Use of PDF 1.4 (PDF/A-1)
![Page 16: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/16.jpg)
The PDF/A standard
• PDF/A is a file format standard
• PDF/A is just one component of a comprehensive preservation strategy
▫ Successful implementation depends upon:
Records management policies and procedures Additional requirements and conditions Quality assurance processes
![Page 17: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/17.jpg)
PDF/A
• PDF/A is intended to address three primary issues:▫ Define a file format that preserves the static visual
appearance of electronic documents over time▫ Provide a framework for recording metadata about
electronic documents▫ Provide a framework for defining the logical structure
and semantic properties of electronic documents
![Page 18: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/18.jpg)
What is in the PDF/A Standard?
• Conformance Levels• Technical requirements▫ Lay out similar to PDF Reference 1.4▫ Defines required, restricted, prohibited
• Best Practices
![Page 19: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/19.jpg)
PDF/A Concept
• Develop a standard based on a restricted subset of PDF
• Published by Internationally recognized standards body such as ISO
• Focus on archive needs of governments, corporations, libraries
![Page 20: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/20.jpg)
PDF/A Usage
• PDF/A standard may be used by vendors to:
▫ Develop applications that read and write and otherwise process PDF/A files
• These applications will be used by organizations to:
▫ Create and process PDF/A conformant files
As part of their business processes
In conjunction with necessary adjunct archival and records management policies and procedures

The PDF/A standard• Multi-part ISO International Standard
▫ ISO 19005-1:2005, Document management –Electronic document file format for long-term preservation – Part 1: Use of PDF 1.4 (PDF/A-1)
▫ Part 2 (19005-2) intended to bring PDF/A into conformance with ISO 32000-1
▫ And additional future parts, as necessary
![Page 23: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/23.jpg)
PDF/A Terminology
• PDF/A-1 refers to the format defined by Part 1 (ISO 19005-1) of the standard
• Part 2 (ISO 19005-2) will define PDF/A-2
• New Parts can be added to the PDF/A family of standards without making previous Parts obsolete
• Conformance Level A identified as PDF/A-1a
• Conformance Level B identified as PDF/A-1b
![Page 24: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/24.jpg)

PDF/A Caveats• However…
▫ PDF/A alone does not guarantee preservation
▫ PDF/A alone does not guarantee exact replication of source material
▫ The intent of PDF/A is not to claim that PDF-based solutions are the best way to preserve electronic documents
▫ But once you have decided to use a PDF-based approach, PDF/A defines an archival profile of PDF that is more amenable to long-term preservation
![Page 26: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/26.jpg)
Definition of Conformance Levels
Conformance Level:
“identified set of restrictions and requirements to which files and readers must comply”
Source: ISO 19005-1
Conformance levels enforce the requirements established in the standard. This is what we mean by conformance level.
![Page 27: What is PDF/A?](https://reader035.vdocuments.net/reader035/viewer/2022081413/546c8871b4af9f7f2c8b50b7/html5/thumbnails/27.jpg)
PDF/A Conformance
• Two Conformance Levels▫ PDF/A-1a (full conformance)
▫ PDF/A-1b(preserves visual appearance
only)
