10 A Proposal Create a new bibliographic metadata infrastructure with the following characteristics…

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

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

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

17 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 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

18 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 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

19 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 Methods to enrich metadata records with additional information Examples: Book cover art Tables of contents Book reviews Robot-collected metadata Authority control records

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

21 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) A rich metadata infrastructure will interoperate with a wide range of standards and protocols Examples: OAI-PMH SOAP (REST)

23 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 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
