The Significance of Archiving
One sure and common phenomenon that has been occurring in all the organizations for decades is their need to back-store cumulative data into a secondary storage device, such as the tape, basically to empty-up primary space as well as preserve historical records. This is known as archiving. The traditional process has now acquired a new outlook with the advent of the ISO certified PDF/A archive technology for using PDF format to electronically back-up capacious info. PDF/A archives need compressing of the files into a single package before writing them into memory. Transmission rate of the compressed data is relatively higher, and the archiving technique renders them easily searchable.
Features of PDF/a Archives
A PDF/A archive is a modern method of ensuring high `electronic reproducability' and 100% shelf-life of data that need to be preserved. PDF/A archives store data in a structured format which means that they can be displayed in reading order, one page after the other. This optimizes searching based on metadata like title, author, creation date, modification date, subject, keywords, etc. PDF/A archives are more condensed and than their corresponding TIFF files, and thus, are replacing them thoroughly. Archiving as PDF document after discarding the compressible contents like repetitive text, unused images, metadata, remarks etc. is one of the space-saving procedure that can exist independent of the tools. Security is another marked feature in case of PDF/A archive files since the documents are virtually untouchable by anyone but the owner.
Methods of Archiving
PDF/Archive, shortly known as PDF/A, are batch processed, compressed and backed-up as PDF archives using server-based software with high speed, compressibility and reliability. The quality of display is of a higher resolution and can be combined with OCR technique for archiving scanned documents. Downloadable plug-in packages are also available for creating PDF/A archive types. Ever since the idea of using PDF for archiving was conceived, there has been significant improvement in that arena with various version releases marking the milestones of development. Further research and continuous development processes are going on to make PDF more and more advantageous for archiving.
