Create once, use many times
How to enable recordkeeping metadata interoperability?
Practical Perspectives
Overcome barriers to implementation of
recordkeeping and resource discovery standards
Demonstrate the business case for recordkeeping
metadata
Research Perspectives
Explore role of recordkeeping metadata in support of
business and recordkeeping processes
Impact on recordkeeping and archiving functions
Requirements for meta-tools for recordkeeping metadata management

Metadata broker as middleware - outcomes
• Observations– Standards not as interoperable as assumed– Complexity in recordkeeping metadata re-use – Limitations of current recordkeeping metadata
standards• Reflections on observations
– Sustainability requires moving beyond hand crafting crosswalks and hard wiring applications
– Constraints of records management and archival processes, technologies and tools developed for paper recordkeeping and in application-centric IT environments
www.monash.edu.au

Second iteration agenda
• Develop metadata broker as a cluster of web services
• Revise scenario processes in line with continuum and SOA view
• Test use of broker within such a framework• Develop business case for recordkeeping
metadata in such a framework

Conclusions
• Extent to which paper paradigms still dominate recordkeeping practice
• Why the service oriented paradigm is desirable for recordkeeping
• Point to the degree of re-thinking required in the profession to make recordkeeping in such environments a reality
• Highlight the infrastructure required to support clever metadata, particularly the role of registries at different levels of operation and granularity

23
Conclusions (continued)
• For schema and standard developers– Moving from compliance to interoperability
requires rigorous conceptual modelling translatable into unambiguous and precise representations for machine processing
– Need for identification and descriptive frameworks for schemas to facilitate their use
