Climbing Mt' Preservation: Architectures and Standards Environments for PREMIS

1
Climbing Mt. PreservationArchitectures and
Standards Environmentsfor PREMIS

• Chris Blackall, APSR

2
Overview

• Digital sustainability/preservation concerns
• Overview of the PREMIS landscape
• Climbing Mt. Preservation a guided tour of
  standards environments through to architectures
  (with examples)
• New service-oriented architectures (and
  approaches)

3
Sustainability

• Sustainable repositories and preservation
• see Kevin Bradley APSR Sustainability Issues
  Discussion Paper January 2005.
• http//www.apsr.edu.au/documents/APSR_Sustainabil
  ity_Issues_Paper.pdf

4
Focus

• Data sustainability
• Preservability
• Interoperability
• Accessibility
• Key concept preservation metadata

5
The Need for Digital Preservation

• Why do we need to do anything to preserve digital
  information?
• The physical technology will change
• The data carrier (physical media)
• The hardware
• The operating environment will change
• Rendering software
• Operating systems
• Supporting software technologies
• The format will become obsolete

Preservation Actions
AIP

• Those steps that might be taken to ensure the
  digital material remains viable.
• Refreshment
• Migration
• Emulation
• Encapsulation
• The primary tool in enabling this process is
  Preservation Metadata

Enterprise Architectures

• What is an enterprise?
• Promoted by big IT vendors as an enterprise
  integration solution
• Complex expensive, e.g. 2006 DIMIA IT contract,
  495mil
• Service-Oriented Architectures (SOA)
• Web Service Standards (W3C OASIS)
• DEST/JISC e-Framework

What about E2E Interoperability?

• Solved by using asynchronous messaging protocols
• Lightweight Remote Procedure Call (RPC)
  protocols REST (Representational State Transfer)
• Heavyweight RPC protocols SOAP (Simple Object
  Access Protocol)
• Metadata harvesting protocols OAI-PMH

Pathways

• Path 1. Accidental architectures/ monolithic
  enterprise applications/feral computing
• Path 2. Enterprise integration using WS standards
  and technologies/semi-virtuous computing
• Path 3. Enterprise Service-Oriented Architectures
  (SOA) and applications/ virtuous computing
