IntroductionFor corporations today, bad recordsManagement is not an option!There are a lot of standards and laws toadhere to...NASD 3010BS 7799MoReqSarbanes-OxleyactD.o.D. 5015.2ISO 15489


ProblemRecords Management Systems (RMS)are used to ensure compliance“- Gartner estimates the worldwide records managementmarket to be approx. $350 mill. in software license andmaintenance revenue in 2006, up more than 30% from2005”Systems used to archive content areseldom good for creation... and viceversa


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


Our GoalModel for archivingcorporate records:- Lightweight- Automated- Flexible- SecureContent +MetadataArchive


Ideal SituationA system to manage the entire documentlifecycleCreateUseContent ManagementManagePreserveTo keep cost and complexity low:move data from CMS to a RMS!DestroyRecords ManagementThis cannot be done out-of-the box withdifferent systems!


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)CMSRMS
