University of Illinois Digitial Library Initiative (IDLI) Metadata Schema Description

Preamble:

This is a preliminary draft document describing the metadata structures used in the DLIB TestSuite and related projects currently in progress at the University of Illinois at Urbana-Champaign Library. The description semantics and format used to describe this metadata schema are derived from part 3 of ISO 11179. Metadata tag names, attributes, and implicit content models are constantly reviewed and modified frequently. Other notes:

Dublin Core (DC) Metadata Initiative semantics are used throughout this metadata schema. The DC tags are documented in the following description for clarity. As much as possible 11179 attributes for DC tags are taken verbatim from the DC Element Set (ver. 1.1) web site, and that site is the authoritative site regarding meaning and usage of DC elements. This description then implies content models for those elements that are particular to our implementation of the DC model.
The metadata schema described here is verbose. As used in this schema, DC elements are repeated for each logical element of content (e.g., each author of a document is described in an individual, separate dc:Creator).
The described metadata schema is designed to be implemented using the Resource Description Framework (RDF) as published 03/03/1999 by the W3C. Most DC elements that are repeatable under this schema are thus enclosed within rdf:Bag, rdf:Seq, or rdf:Alt as most appropriate.
This description is presented in well-formed XML. This XML file validates against a version of the CNRI DLIB TestSuite DTD adopted for this project that has been modified to allow a few additional attribute values.
The 'idli' namespace is currently not registered with any central naming authority and is reserved for local use only at this time.

A simple table format listing all these element is also available.

List of all elements (alphabetical):
