A ProposalA Proposal

Create a new bibliographic metadata infrastructure with the following characteristics…

Create a new bibliographic metadata infrastructure with the following characteristics…

A Transfer SchemaA 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 ]

Bibliographic SchemataBibliographic SchemataWe must like any metadata we see:

ONIX records from publishers

MARC records MODS records

Dublin Core

RFC 1607

VRA Core

etc.

General application rules

Best PracticesBest 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

CrosswalksCrosswalks

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

Why It MattersWhy 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
