DAMS Implementation at NLW DAMS Implementation at NLW 20 th February 2007 Paul Bevan

DAMS Implementation at NLW A DAMS for NLW Marketplace Review Consultancy Review – FEDORA & DSpace Pilot Project –What can we achieve? –What work is to be done? Procurement as part of Integrated Library Management System. –Virtua, Vital, Verify, etc

DAMS Implementation at NLW DAMS Implementation 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 –Secure our assets in a way which is open to preservation

DAMS Implementation at NLW Managing the Implementation Staffing: –Implementation Group comprising mix of standards, IMS project management, technical, and digitisation staff. [Carried over from pilot] –2 DAMS Implementation Managers (Systems & Technical) –Key interactions with other personnel as required. Communication: –Implementation Group Meetings –Project Board Reports –dev Wiki

DAMS Implementation at NLW About FEDORA Flexible Extensible Digital Object and Repository Architecture –Strong userbase –Open-Source –Clear development pattern –Flexible! –Extensible!

DAMS Implementation at NLW About VITAL Product of VTLS Inc. –Based on FEDORA –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) –Live Failover (DataGuard) Our Platform –Vital 3 –Fedora –Oracle 10i –Twin Servers (with live failover)

DAMS Implementation at NLW Approach Object Review (complete) Prioritisation (Digitised Still Images)(complete) Defining Object Types (complete) Make existing Digital Archive accessible (complete) METS (complete) Develop Ingest Processes Develop Management Processes (eg. Checksumming) Testing and Final Ingest  Release 1: Transparent Dissemination of Digitised Still Images (March 2007)

DAMS Implementation at NLW Access Points & Metadata (Overview) Access Via –PRIMARY: Catalogue (Single Sign On…) –SECONDARY: ‘Exhibitions’ –TERTIARY: OAI-PMH, PIs Metadata –METS & MARC : Administrative & Descriptive –Split to minimise inconsistencies (but, NLSing…) –METS holds policy, therefore outside of FEDORA (but enforced by FEDORA) – future proofing. –METS as SIP, AIP and DIP

OAIS METS Digital Archive Virtua VITAL Disseminators MARC

DAMS Implementation at NLW Example: Rights-Access METS = Policy, FEDORA = Enforcement 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. Example Policies: Repository-wide Policy Deny access to the deleteDatastream method of API-M if user is not “author” Object-specific Policy Deny all access to the object “llgc:100” if user is a not located within Wales. Genre-oriented Policy Given that an object conforms to the content model type of “journal-article,” deny access to the “getFullArticle” if the user is not in the group “registered” Time-oriented Policy Permit users access to “embargoed” datastream of digital archival collection after January 06, 2009

Content Model: Object (AIP) All Objects must Contain METS DS DC DS (OAI-PMH) Relationships DS Objects below collection level must contain Object Files (!) DS: METS DS: DC (OAI-PMH) DS: Relationships DS: Object (eg. TIFF File) DS: Object (eg. JPEG File) DS: Object (eg. Thumbnail File) ….
