Layers of interoperability
Layer 1 Transport and Exchange
From Thomas Baker et al., Principles of Metadata
Registries, 2002
12
To make this happen

• Stop assuming existing standards are
  interoperable

13
To make this happen

• Rigorously define metadata interoperability in
  terms of element semantics, their value domains
  and encoding schemes
• Develop concrete recordkeeping metadata standards
  based on dynamic metadata models with multiple
  entities
• Develop machine processable versions of standards
  representing both the syntax and semantics

14
To make this happen

• Implement the metadata broker concept
• Build operational web services to enable metadata
  translation
• Re-engineer and re-position recordkeeping and
  archiving processes in line with a continuum view
• Realise the vision Create Once, Use Many Times

15
Project Deliverables

• Conceptualise and Build the Metadata Broker as a
  Web Service
• Services in and out of scope
• Metadata Registry Requirements
• Registration interface
• Validation Services
• Thesis contribution investigating types of
  metadata interoperability.
• (Oct/Dec 2005)

Re-engineering work processes

• Test whether re-engineered work processes within
  a continuum framework can support optimal use of
  the Metadata Broker as a Web Service.
• What infrastructure must be available to the Web
  Service
• Feedback to standard setters
• Tools?
• Impact on organisational work processes?
• (Late Nov 2005)

18
Evaluation

• Evaluate whether there is a business case
  supporting clever metadata reuse?
• (Jan/Feb 2006)

Conclusion

• Reporting
• Demonstrator (April 2006)
