2 Existing Solutions for Scanned Documents Black & White: TIFF G4 Color: Mostly JPEG, but sometimes PNG, BMP and other raster graphics formats Often special version formats like JPEG in TIFF Disadvantages: Several formats already for scanned documents Even more formats for born digital documents Loss of information, e.g. with TIFF G4 Bad image quality and huge file size, e.g. with JPEG No standardized metadata spread over all formats Not full text searchable (OCR) inside of files Black/White: - TIFF FAX G4 Color: - TIFF - TIFF LZW - JPEG - PDF 2

3 Existing Solutions for Scanned Documents Bad image quality vs. file size TIFF/BMP JPEG TIFF G MB 180 kb 60 kb 3

4 Alternative Solution: PDF PDF is already widely used to: Unify file formats Image PDF Office Documents PDF Other sources PDF Create full-text searchable files Apply modern compression technology (e.g. the JPEG2000 file formats family) Harmonize metadata Conclusion: PDF avoids the disadvantages of the legacy formats So if you are already using PDF as archival format, why not use PDF/A with its many advantages? 4

5 PDF/A What is PDF/A? ISO , Document Management Electronic document file format for long-term preservation Goals of PDF/A: Maintain static visual representation of documents Consistent handing of Metadata Option to maintain structure and semantic meaning of content Transparency to guarantee access Limit the number of restrictions

6 PDF/A Full-Text Searchability (OCR) Benefit: Searchable at the File Level Digital Library - after book download Large Manuals / Multi-Page Construction Documents Downloaded Documents from Archive Databases Documents sent to customers, suppliers, lawyers, etc. as attachments 6

7 PDF/A Enhanced Compression For Black & White Documents JBIG2 - ISO/IEC Used as alternative to TIFF G4 Full and visual lossless mode Embedded in PDF/A, available in Acrobat Reader FAX G4 JBIG2/lossless JBIG2/lossy 60 kb 46 kb 29 kb 7

8 PDF/A Enhanced Compression For Color Documents MRC Compression, also known as JPEG2000 (JPM) Splits documents in three layers to be compressed independently and stored in PDF/A 8

9 PDF/A Enhanced Compression For Color Documents Extreme compression, fully legible Saves the color and the visual quality TIFF TIFF G4 JPEG PDF/A 23,8 MB 60 kb 180 kb 65 kb 9

12 Question: PDF/A: hype or the future archiving format? 12

13 PDF/A Example e-government Medical and Student Records State of New York Long-term Archive Department of Health Department of Education Project Outline Previously using 1 terabyte of storage every 2 weeks Capture all documents with Scan Service Provider with Fujistu and Kodak scanners Convert images to optimized PDF/A with LuraDocument PDF Compressor Deliver and store PDF/A documents with ECM Results High compressed PDF/A files reduce storage costs and bandwidth needs by 90% Long term readability of all files with retention time of over 40 years Files are now available quickly for daily research AIIM 2008: Best Practices Award GTC West 2008: Best Solutions Award 13

14 PDF/A Example Credit Files Mailroom for credit files and international checks Example: HeLaBa (German State Bank) Mailroom Revenue: 168B Euros Employees: 5,700 Project Outline Convert 20 Mio. Pages paper based archive to PDF/A Convert all daily incoming mail to PDF/A Create complete electronic credit files Used tools: LuraTech PDF Compressor, Kofax Ascent, EMC Centera, Wincor Nixdorf archive:net (Taxnet) Results Full color scans in electronic archive High compressed PDF/A files Full text searchable credit files Long term readability of credit files First step on the way to single archiving format 14
