Clever Recordkeeping Metadata Project ARC Linkage Project 2003-2005 Chief Investigator • Professor Sue McKemmish, Monash University Partner Investigators • Professor Anne Gilliland-Swetland, UCLA • Mr 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 http://www.infotech.monash.edu.au/research/groups/rcrg/crkm

  3. Imperatives for recordkeeping metadata interoperability • … Most organizations have serious operational problems regarding the processes by which they manage electronic records, one of their most important assets. … • … Many of the findings are worse than they otherwise might be because the business functions required to successfully manage electronic records operate in an independent “silo” context. … • … The number and magnitude of organizational and operational problems reflected in the survey findings collectively create stunning business risks. Robert F. Williams and Lori J. Ashley, 2005 Electronic Records Management Survey 2005 – A Renewed Call to Action White Paper, Cohasset Associates Inc., 2005, 68 pp, http://www.merresource.com/pdf/survey2005.pdf

  7. First iteration 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

  8. Second iteration agenda • Develop CRKM Broker as a cluster of web services • Revise scenario processes in line with continuum and service oriented • Test use of the CRKM Broker within such a framework • Develop business case for recordkeeping metadata in such a framework

  9. Second iteration CRKM Broker Validation service Target metadata Source metadata Translation service Crosswalk compilation service Crosswalk compilation service Registration Registry services Schema information Repository Machine processable representations of metadata schemas and crosswalks Registry Authoritative information on metadata schemas, metadata elements and crosswalks in human readable and machine processable forms Request for Schema

  10. Registry Evaluation • Registry Standards and Specifications • ISO/IEC 11179 Metadata Registries standard (1994 – ) • ebXML Registry specification (1999 – ) • UDDI Registry specification (2000 – ) • Registry Prototypes • Dublin Core Metadata Registry (1999 – ) • DESIRE Metadata Registry Framework (1998 – 2000) • SCHEMAS: Forum for Metadata Schema Designers and Implementers (2000 – 2001) • CORES – A Forum on Shared Metadata Vocabularies (2002 – 2003) • MEG Registry Project (2002 – 2003) • JISC IE Metadata Schema Registry (2004 – 2005) • InterPARES 2 Metadata and Archival Description Registry and Analysis System (MADRAS) (2003 – 2006) • Translation Research Projects • Harmony Project (1999 – 2002) • OCLC Metadata Schema Transformation Services, Metadata Switch (2002 – 2004)

  11. Registry Timeline

  12. Types of registries • General • Manage metadata and pointers to resource objects • e.g. UDDI, ebXML, MADRAS • Metadata • manage metadata about the semantics and syntax of metadata • e.g. ISO/IEC 11179, Dublin Core Registry, DESIRE/SCHEMAS/CORES/MEG/JISC IE Registry Prototypes

  13. Second iteration CRKM Broker Validation service Target metadata Source metadata Translation service Crosswalk compilation service Crosswalk compilation service Registration Registry services Schema information Repository Machine processable representations of metadata schemas and crosswalks Registry Authoritative information on metadata schemas, metadata elements and crosswalks in human readable and machine processable forms Request for Schema

  14. ebXML Registry • Two part specification of requirements for object repository and associated registry • ebXML Registry Information Model • ebXML Registry Services and Protocols • Availability of freeBXML Registry - open source reference implementation of an ebXML Registry • see http://ebxmlrr.sourceforge.net/

  15. CRKM Registry Implementation Framework UDDI Registry UDDI Registry UDDI Registry WSDL service descriptions CRKM Registry ebXML Registry External links to entries for versions of standards Querying for schema and crosswalk objects MADRAS Registry

  16. Metadata broker as web services cluster CRKM Registry ebXML Registry CRKM Broker Schemas Crosswalks

  17. Request the AGEMS – RKMSCA crosswalk Translation Service Metadata Registry Web Service Layer Web Service Layer Request to translate AGEMS to RKMSCA AGEMS – RKMSCA Crosswalk Service AGEMS RKMSCA Web Service Layer Metadata broker as web services cluster Metadata Broker Client

  18. Layer 3 Abstract Layer 2 Representation CRKM Registry Information Model Conceptual Model Metadata/Data Standard Metadata/Data Standard Metadata/Data Standard Version 1 Version 2 Version n Encoding 1 Encoding 2 Encoding n Registry Objects Version 1 Version 2 Version n
