A DAMS for NLW • Consultancy Review & Pilot Project • Procurement as part of Integrated Library Management System. • Key Goals: • Ingest, manage and disseminate objects • Support current and future digitisation, digital archiving and digital collection projects. • Achieve seamless integration • Provide a platform for future dissemination methods • Open access to our digital data, within a rights-managed environment.
About VITAL • Product of VTLS Inc. • Based on FEDORA (Open Source, Increasing Uptake, Flexible & Extensible) • Client • Access Portal • VALET • Handle Server • Allows the flexibility of Open Source within a managed and supported framework. • Certain Developments Required • Shift to Fedora 2.1 (complete) • Integration (Authentication)
Approach • Object Review (complete) • Prioritisation(Digitised Still Images) (complete) • Defining Object Types (complete) • Make existing Digital Archive accessible (complete) • METS (complete) • Develop Ingest Processes (complete) • Develop Management Processes (eg. Checksumming) (complete) • User-Interface Development • Testing and Final Ingest • Release 1: Transparent Dissemination of Digitised Still Images (May 2007)
Virtua-Vital Integration • Aim: Management of traditional and digital assets through a single integrated system • Integration Provides: • Central Point of Access • Shared Methods of Management • Most Effective Use of Existing Skill Sets • Seamless Access
Integrated Metadata • Metadata exists in only one part of the system (mostly) • Descriptive Metadata in Virtua • Administrative Metadata in VITAL (eg. Rights, Preservation) • Some Descriptive Metadata in VITAL for administrative discovery • FUTURE: Synchronisation?
Linkages • Every Vital Object is linked to a Virtua MARC Record (at some level) • Virtua VITAL: Handle in 856 of a Holdings record • 4 1 $3 C09663 $q image/jpeg $u http://hdl.handle.net/10107/20 $y Gweld yr eitem = View the item • VITAL Virtua:Attribute in METS Document <METS:sourceMD ID="sourceMD2"> <METS:mdRef LOCTYPE=“DOI" MDTYPE="MARC" xlink:href="vtls003351559" xlink:type="simple" /> </METS:sourceMD>
Integrated Access • Transparent to the End User • Seamlessness with iPortal • User shouldn’t realise they’ve switched from Virtua to VITAL. • Carrying over of relevant session, rights and searching information. • Developments • ‘Direct’ Access • Google, • Handles • IMG tags? • Rights Managed

Policies & Enforcement • Object Policies • METS = Policy, FEDORA = Enforcement • Eg. Rights: • FEDORA uses XACML (eXtensible Access Control Markup Language) to enforce rights on one or a group of objects within the repository. Rights are based on XACML statements constructed from the METS:Rights from METS document. • Repository-Wide Policies • Every Object had METS • Every Object is linked to a MARC record • Every Object has DC (OAI/Internal Use)
Ingest • Start with MARC record • Used to create Dublin Core data • Shows location of content (through 856) • Creates the METS • METS used as SIP • MARC updated with new holdings (with handle in 856)
OAIS Ingest • Creation of SIP Submission information Package Ingest MARC to METS Program Generate SIP MARC Record Descriptive Information Ingest Ready METS SIP Objects Content Objects Content Default METS
SIP (METS) • METS Header: • History of METS document • Descriptive Meta Data • mods on digital copy • link to dc for original • premis details on original file name • relationship information to other objects in Fedora • Administrative Meta Data • mix technical meta data on images • dc legacy technical data • premis admin data including checksums, and relationships between data streams • link to MARC record in Virtua • Digital Providence • List of actions that have occurred to the object • List of agents who ran the software / versions of the software used • File Sec • List of Data streams linking above sections to particular data streams • Structural Map • First one allows display via a METS viewer type application • Subsequent ones are linked to Disseminators • Behaviour Section • Links objects to their dissemination
