Dublin Core Intro

  1. 1. Introduction to Unqualified and Qualified Dublin Core Metadata <ul><li>Richard Wisneski, Virginia Dressler </li></ul><ul><li>Kelvin Smith Library </li></ul><ul><li>Case Western Reserve University </li></ul>Fall 2008
  2. 2. Part 1: Dublin Core Background
  3. 3. What Is Dublin Core? <ul><li>General Descriptive Metadata </li></ul><ul><li>MARC inspiration, but not its equivalent </li></ul><ul><li>Dublin Core is NOT meant to replicate MARC </li></ul><ul><li>Abstract model is the current focus </li></ul><ul><ul><li>e.g. DC record would report on slide of Mona Lisa, not necessarily the Mona Lisa itself. </li></ul></ul><ul><li>Unqualified DC is generally used as a format for sharing metadata with others </li></ul><ul><li>DC provides an information model that is independent of any specific encoding syntax </li></ul>
  4. 4. A little history…. <ul><li>1998: Dublin Core Element Set version 1.0 </li></ul><ul><li>1998: Internet RFC2413 </li></ul><ul><li>1999: Dublin Core Element Set version 1.1 </li></ul><ul><li>2000: EU Recommendation: CEN CWA 13874 </li></ul><ul><li>2001: US National Standard: NISO Z39.85 </li></ul><ul><li>2003: International standard : ISO 15836 </li></ul>

  6. 6. DCMI Resource Model <ul><li>Each DC value represents a physical, digital or conceptual entity </li></ul><ul><li>Each value can be defined to a particular vocabulary (LC subject headings, AAT, etc.) </li></ul><ul><li>Built on the World Wide Web Consortium (W3C) using the Resource Description Framework (RDF) </li></ul><ul><ul><li>Each described resource uses one or more property-value pairs </li></ul></ul>
  7. 7. Interoperability <ul><li>DC represents a set of interoperable online metadata standards that support a broad range of purposes and business models </li></ul><ul><li>OAI-PMH- Open Archives Initiative Protocol for Metadata Harvesting </li></ul><ul><li>OAIster- http:// </li></ul>

Antiphonal or responsive singing is said to have been introduced in the second century by St. Ignatius of Antioch. According to legend, he had a vision of a heavenly choir singing in honor of the Blessed Trinity in the responsive manner. Many of the more than four hundred antiphons which have survived the centuries are elaborate in their musical structure. They were sung in the medieval church by the first cantor and his assistants. Candle grease stains reveal that this small-sized antiphonal was doubtless carried in processions in dimly lighted cathedrals. In this example the notation is written on the four-line red staff which was in general use by the end of the 12th century. The script is the usual form of Italian rotunda with bold Lombardic initial letters.
