Clever Recordkeeping Metadata Project Chief Investigator • Professor Sue McKemmish, Monash University Partner Investigators • Professor Anne Gilliland-Swetland, UCLA • Adrian Cunningham, National Archives of Australia Industry Partners and Collaborators • National Archives of Australia • State Records Authority of New South Wales • Australia Society of Archivists, Committee on Descriptive Standards
Practical Perspectives Overcome barriers to implementation of recordkeeping and resource discovery standards Research Perspectives Explore role of recordkeeping metadata in support of business and recordkeeping processes Demonstrate the business case for recordkeeping metadata Impact on recordkeeping and archiving functions Requirements for meta-tools for recordkeeping metadata management Create once, use many times How to enable recordkeeping metadata interoperability?

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
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
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
