CIC Metadata Portal

Schemas and Crosswalks

A metadata format is a series of rules and elements defined in order to ensure a common semantic understanding of a resource. A metadata format can be (and arguably should be) expressed in various forms, e.g.:

a text document or Web pages maintained by an institution having recognized authority in the sector
a DTD (for SGML or XML encoding of metadata)
an XML Schema (for XML encoding of metadata)

The OAI protocol relies on the ability to explicitly validate metadata through the application of XML schemas. All data providers must refer to the appropriate schema(s) for their metadata.

The CIC portal encourages content providers to share complete metadata records in the richest metadata formats available. CIC OAI metadata providers should also adhere to accepted best practices for the use of the OAI protocol. The following technical references can be used to share various metadata formats.

OAI Framework

Encoding of oai identifiers (compliant with URI scheme RFC 2386 )
Documenting the provenance of a record (implemented in the CIC portal to trace the records it collects from all universities)
Branding collections in order to clearly identify the institution and collection an item belongs to. This is to be displayed on the portal when presenting a specific resource. Guidelines for implementations are available on the Open Archives Website

Dublin Core

The oai_dc schema
CIC Qualified Dublin Core schema contains only DC and DC terms. It is maintained by the University of Illinois at Urbana-Champaign for the CIC

Description of the Qualified Dublin Core format

MODS

MODS schema
The library of Congress also publishes the Xschema for MODS 3.0
Simple DC to MODS crosswalk This is not a stylesheet
MARCXML to MODS stylesheet by the Library of Congress

MARC

MARCXML schema maintained by the Library of Congress for MARC21. A full documentation is also available
MARCXML to OAI-DC stylesheet (cross-walk) maintained by the Library of Congress.
Dublin Core to MARCXML stylesheet maintained by the Library of Congress.
MARCXML to Qualified DC stylesheets maintained by the University of Illinois at Urbana-Champaign for the IMLS digital collections project. You should also download a utility file

EAD

A schema for EAD finding aids developed and implemented in an OAI data provider by Princeton university
Experimental XSLT to map one EAD finding aid to multiple OAI-DC records Created by the University of Illinois at Urbana-Champaign for the Digital Gateway to Cultural Heritage Material Cultural Heritage
Tools to convert EAD 1.0 records to EAD2002
