Duff Johnson: Why validation? – This presentation was given at the Technical Conference 2012 of the PDF Association, March 27-28, 2012 in Basel, Switzerland. [...]
A large international energy provider needed to archive documents relating to nuclear power plant operations. Legal and regulatory requirements mean some of these documents need to be retained for a very long time. The archive system used a repository equipped with a web client. Users left all documents there in their native formats, including TIFF, Word, Excel and many others. Some of these documents then had to also be stored on microfilms, which of course meant a large amount of manual work. Almost 200,000 documents, some of them multi-page and large-format, were stored here every month. Learn how LuraTech helped to successfully convert millions of documents. [...]
This ECM software suite offers complete support of the ISO standard PDF/A. The OS_PDF/A dispatcher module provides the central interface to integrated conversion and validation components from third-party vendors (LuraTech, callas software). Documents from countless original formats can be converted to PDF/A and validated, before they are archived. [...]
The pdfaModul is an add-on to the Jaws PDF Server, and can be integrated into every workflow as a CLI component. Newly created PDF files are checked against the PDF/A standard, typical error sources are corrected, and the Jaws PDFs are converted to valid PDF/A files. [...]
This test suite comprises a set of files which can be used to check the conformance of software regarding the PDF/A-1 standard. More precisely, the Isartor test suite can be used to “validate the validators”: It deliberately violates the requirements of PDF/A-1 in a systematic way in order to check whether PDF/A-1 validation software actually finds the violations. [...]
PDF/A is the PDF for the long-term archiving. PDF/A – adopted in late 2005 – is the first file format as an ISO standard guarantees [...]
Topics include validation, challenges with creating a perfect PDF/A document and more. Also examines that a PDF/A file is a formally correct file, that however may not necessarily reflect the original. If, when a PDF/A file is created, fonts are replaced or colours are converted, then the result may well be a technically correct PDF/A file, but a change has been made with respect to the original file. This aspect is just one of many topics that will be addressed at the 3rd International PDF/A Conference in Berlin. [...]
The PDF/A Competence Center’s technical working group has released the Isartor test suite, which can validate the quality of PDF/A files. It contains over 200 files which systematically violate all the requirements for PDF/A-1b. This enables users and software providers to determine whether a PDF/A validator actually tests all the rules for PDF/A-1b. [...]
