Digital initiatives

Overview

• Collecting for the Library• Policies• Strategies• Frameworks for Digitial Initiatives

– DAMS– OAIS & METS– Object Models– Workflows

• The Way Ahead

Digital initiatives

Collecting Digitally

• Remit:

To collect, preserve and give access to all kinds and forms of recorded knowledge, especially relating to Wales and the Welsh and other Celtic peoples, for the benefit of the public including those engaged in research and learning.

Digital initiatives

Digital for Access

• Wider Community

• At Home, At School, At Work

• Open Access

• VLEs

• New Ways of ‘Thinking About’ Resources

Digital initiatives

Digital for Preservation

• Safeguarding the Original

• Digital Preservation Copy

• Backups

• But, shift in emphasis (preservation of the digital surrogate).

Digital initiatives

Digital Policies

• Digitisation Policy

Why Digitise?• Access (Physical Distance, Number of Users)

• Enhance (Full-Text, e-Learning Environmnets, Virtual Collections)

• Preservation• Promotion• Revenue Generation

Digital initiatives

Digital Policies

• Digital Preservation Policy– Support Digitisation– Prepare for Legal Deposit Legislation– Identify & Prioritise Existing Material Within

Collections– Evolve Best Practices– Create/Implement Tools as Required

Digital initiatives

Digital Strategies

• Digitisation Strategy

– Define projects/programmes– Digitise Material According to a Selection

Matrix– Collaborate with other Organisations– Seek User Feedback

Digital initiatives

Digital Strategies

• Digital Preservation Strategy

– Identify Existing Digital Assets– Prepare for Expected Material Types– New Ways of Collecting E-Material (eg.

Online Self Deposit)– Build and Implement Infrastructure– Collaborate with other Organisations

Digital initiatives

‘Frameworks’ for Digital Initiatives

An institutional approach bringing together all of the processes of digitisation, digital collection and digital asset management.

• Digital Asset Management System• OAIS• METS• Content Models• Workflows

Digital initiatives

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)

Digital initiatives

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)

• Testing and Final Ingest (current)

Digital initiatives

Object Classes• Class 1

– 1 MARC Record– 1 Image– No METS

• Class 2– 1 MARC Record– Many images– No METS

• Class 3– 1 MARC Record– Many Images– 1 METS for each Record

• Class 4– 1 MARC Record– Many Images– Many METS

Digital initiatives

Next Steps

• Further Object Types:• Other Digital Still Images(CNC)• Audio-Visual Resources (inc. off-air)• ePrints• Digital Archives• Self-Deposit• Websites

• More Varied Disseminations:• Project/‘Exhibition’ websites• Interactivity• Preservation Tasks

AIP (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

Digital initiatives

METS: Rights-Access

• METS = Policy, DAMS = Enforcement• DAMS 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 (!)

Digital Collection Project Framework

• Off-Air Recording

– NSSAW Archive records all Welsh broadcasts from TV & Radio

– Traditionally Analogue, recently procured a digital solution

– Ingest of Digital Files & Metadata into Virtua/Vital system automatically

– Dissemination through individual MPEG2 Broadcast Streams

The Way Ahead

• A framework which supports– Digital Collection– Digitisation

• A framework which enables– Digital Preservation– Full Asset Management

• A framework which encourages– New methods of access– Open conduits to materials (eg. Mashups, etc)
