1 Constructing a Records Archiving System Using Off- the-shelf Tools - A Lightweight Approach IWAW 2007 Jan Askhoj,, Mitsuharu Nagamori, Shigeo Sugimoto Tsukuba University, Japan

2 Outline Problems with corporate archive systems Our Goal Proposed Model Use Case Technical Details & Implementation Current work & Concluding remarks

3 Introduction For corporations today, bad records Management is not an option! There are a lot of standards and laws to adhere to... NASD 3010 BS 7799 MoReq Sarbanes-Oxley act D.o.D ISO 15489

4 Problem Records Management Systems (RMS) are used to ensure compliance - Gartner estimates the worldwide records management market to be approx. $350 mill. in software license and maintenance revenue in 2006, up more than 30% from 2005 Systems used to archive content are seldom good for creation... and vice versa

5 Furthermore... Many kinds of Content Management Systems in use: - Web Content Management - Digital Asset Management - Document Management - etc. All these may contain content that needs to be archived!

6 Our Goal Model for archiving corporate records: - Lightweight - Automated - Flexible - Secure Content + Archive

7 Ideal Situation A system to manage the entire document lifecycle Create Use Content Management Manage Preserve To keep cost and complexity low: move data from CMS to a RMS! Destroy Records Management This cannot be done out-of-the box with different systems!

8 Moving Records: - By hand? Bridging the GAP - By custom export-import scripts? A model is needed for CMS RMS archiving (that works with exiting systems) CMS RMS

9 Three Layered Model CMS RMS 1 Content Conten t Record Content Import 2 Archive metadata Import Transport 3 Transport package Reader and Interpreter Transport/ Negotiation

10 Information Flow: Export CMS Content User submits content Retention by content type extracted Transport + content packaged Transport Package made avalible

11 Information Flow: Import RMS Content is approved and imported Record is approved and imported Package is read is converted Trackback is returned Reader and Interpreter

12 CMS/RMS Schemes CMS metadata cannot be used by the RMS as-is - CMS metadata schemes: Can vary according to application or content - RMS metadata scheme: Designed for Records Management CMS Schemes N 1 RMS Scheme

13 Authority Offers metadata conversion Requires that CMS register URI and Scheme in advance CMS 1 URI: foo Schema:A Transport Package Authority RMS Schema:X CMS 2 URI: bar Schema:B Transport Package if URI=foo if URI=bar Translation table A X Translation table B X

14 Example : Conversion CMS 1 Schema:A Authority Translation table A X Transport Package RMS Schema:X Author: John Smith Creator: Smith, John Only works with compatible metadata

16 Implementing ATLAS Automated Transfer Lightweight Archive Solution Existing System Requirements: - CMS: Expandable, publish necessary content and metadata - RMS: Import functionality, supporting XML

17 Protocol RSS 2.0 (Really Simple Syndication) - XML based - Lightweight - Expandable - Already supported Need to Expand:, Authority URI, Security

18 Security & Trackback Authentication & Access: HTTP Login Data Integrity: Checksum CMS Confidentiality: SSL Confirmation: Trackback RMS Content Package Trackback Aggregater

19 CMS System Overview Trackback RMS Existing systems Export Module Packaging - Record - Record - Transport Authority Import Module Import Approval ATLAS Add-ons Checksum Feed Reader Prepare for Ingest (Temp. Database) Advertise RSS Feed SSL + HTTP login Checksum

20 Issues & Current Status Issues - CMS must have good metadata - No provision for long term-storage - Requires good archiving environment Current Status - Building ATLAS using... CMS: Drupal RMS: Dspace Ruby on Rails

21 Concluding Remarks Model suited to problem - Simple to implement - Reduced cost - Open for expansion, modification - Guarantees safe transfer
