PDF/A for long-term archiving conforming to ISO standard

Last year the International Organization for Standardization (ISO) approved PDF/A as the standard file format for long-term archiving. This will give companies and public authorities the certainty of knowing that the documents which they archive using this format will remain the same over a long period of time - and will do so irrespective of

the applications and systems with which they were created.

PDF/A is the ISO 19005-1 standard for long-term archiving in PDF format. It is a constrained version of PDF, a standardised subset of PDF used for long-term archiving. The syntax specification goes into detail regarding permissible and prohibited content. These prescriptions and other stipulations are intended to guarantee that the documents will be readable for a long time to come. Recognised experts are assuming that the ISO standardisation will very quickly raise the profile of PDF/A format and that it will not be long before PDF/A format replaces TIFF format - if for no other reason than because of its full-text search capability.

The compression technology developed by LuraTech produces very small

file sizes, including for PDF/A files with and without full-text recognition

The LuraDocument file format "JPM" is the world's first implementation of the new ISO standard JPEG2000 Part 6 for the compression of scanned colour documents containing both bitonal elements (text, technical drawings) and images. Text and image components are segmented and compressed separately, each with the optimal algorithms. In the process, the bitonal layer is stored losslessly in Fax Group 4 format while the foreground and background layers are compressed using the JPEG2000 standard. The result is excellent text and image quality combined with extremely small file sizes.

The LuraDocument "JPM" file format is eminently suitable for use in document management systems (DMS) and geographical information systems (GIS).
