Which one of these metadata sets is NOT predefined in GSDL? 

The Correct answer is ​PREMIS.

Key Points

• GSDL:
  • The Greenstone Digital Library (GSDL) software is developed by the University of Waikato.
  • Greenstone is issued under the terms of the GNU General Public License. It originated in 1996.
  • Greenstone has two separate interactive interfaces, the Reader interface and the Librarian interface.
  • Metadata formats:
    • ​Users define metadata interactively within the Librarian interface.
    • Unlike DSpace Greenstone allows several sets of metadata, including locally produced ones to be merged.
    • The metadata sets are predefined:
      • ​Dublin Core (qualified and unqualified)
      • RFC 1807
      • NZGLS (New Zealand Government Locator Service)
      • AGLS (Australian Government Locator Service)​

Additional Information

• Dublin Core:
  • Dublin Core is a metadata standard used for describing electronic resources such as web pages, images, videos, and other online documents.
• RFC 1807:
  • ​RFC outlines a structure for bibliographic records that provide descriptions of technical reports.
  • The format specified in this RFC is utilized by the Cornell University Dienst protocol and the Stanford University SIFT system.
  • Originally authored by D. Cohen at ISI in July 1992.
• ​NZGLS:
  • ​The NZGLS Metadata Standard plays a crucial role in the e-government initiative, providing a standardized method for cataloging government information and services through a set of common terms known as 'metadata elements.'
  • Functioning similarly to a library catalog, the NZGLS, when combined with Internet search engines that utilize its metadata, significantly enhances the discoverability of government information and services.
• PREMIS:
  • ​PREMIS (PREservation Metadata: Implementation Strategies) stands as the predominant digital preservation metadata standard.
  • In the context of digital preservation, metadata plays a vital role in defining the information necessary to ensure the long-term usability of digital objects, securing their accessibility in the future.
