  6. Infrastructure Requirements • Versatility • Extensibility • Openness and Transparency • Low Threshold, High Ceiling • Cooperative Management

  7. Infrastructure Requirements cont’d • Modularity • Hierarchy • Granularity • Graceful in failure

  8. A Proposal • Create a new bibliographic metadata infrastructure with the following characteristics…

  9. A Transfer Schema • An XML schema for ingesting, storing, and transferring multiple bibliographic metadata packages intact • A current example: the Metadata Encoding and Transfer Syntax (METS) [ demo ]

  10. Bibliographic Schemata • We must like any metadata we see: • ONIX records from publishers • MARC records MODS records • Dublin Core • RFC 1607 • VRA Core • etc.

  11. Application Rules • The “AACR2” of our new infrastructure • Rules and guidelines for use: • General application rules • Schema-specific rules

  12. Best Practices • Implementation practices — “on the ground” rules of thumb and procedures • Because not everything should be codified in application rules — room should be allowed for experimentation • In these “gray areas” best practices can suggest non-prescriptive and reasonable sets of procedures

  13. Crosswalks • Librarians Should be able to walk, talk, eat, and drink metadata of all varieties • Proficiency at this will require crosswalks, or algorithms for translating metadata from one schema to another • The same infrastructure could be used to merge multiple formats into a searchable index

  14. Enrichment Services • Methods to enrich metadata records with additional information • Examples: • Book cover art • Tables of contents • Book reviews • Robot-collected metadata • Authority control records

  15. Tool Sets • Tools to help us manage and manipulate metadata • Examples: • XSLT Stylesheets • Crosswalking code (e.g., OCLC’s Metadata Switch service) • OCLC’s FRBR algorithm

  16. Relationships to Other Standards and Protocols • A rich metadata infrastructure will interoperate with a wide range of standards and protocols • Examples: • OAI-PMH • SOAP (REST)

  17. Challenges • Adapting to a diversity of record formats • Crosswalking and Merging • System migration • Staff retooling • Your favorite challenge here…

  18. Why It Matters • We face many challenges and opportunities • Events have left our once robust metadata infrastructure behind — both conceptually and technically • Our users and the services we wish to provide them demand a metadata infrastructure equal to the tasks before us • We can and should seize the opportunity to recreate our foundational infrastructure
