This workshop was presented at MTSR-2017 (Nov. 27, 2017) in Tallinn, Estonia http://www.mtsr-conf.org/index.php/programme The workshop aims to bring the current metadata landscape in libraries in context, with particular emphasis on emerging theory/principles and best practices covering:
• The theory of enriching and filtering
• Metadata enriching through RDA (Hands on - The RDA Toolkit and implementation of RDA at Southampton Solent University)
• Metadata filtering through FRBR (practical issues that cataloguers face in FRBRising their catalogue)
• Metadata management (metadata quality, authority control and subject headings)
• Metadata systems, tools and applications (practical issues of e-books and database cataloguing)

Current metadata landscape in the library world Getaneh Alemu

  1. 1. Current Metadata Landscape in the Library World Getaneh Alemu (PhD) Cataloguing & Metadata Librarian Southampton Solent University @getaneha MTSR-2017 11th International Conference on Metadata and Semantics Research November 28th – December 1st 2017, Tallinn, Estonia
  2. 2. METADATA LIBRARIAN
  3. 3. We’ve come a long way… “The catalogue guides the reader as far as the location of the book but not to the contents within and also relationships between documents.” (Paul Otlet)
  4. 4. ..the future of the card catalogue
  5. 5. Online Public Access Catalogue (OPAC) 813.54 GRI
  6. 6. .. and then AACR2
  7. 7. But information grows … “Metadata liberates knowledge.” David Weinberger  > 4 billion pages on the Web  It would take 57,000 years to read  Determining relevancy and prioritising is challenging Metadata. (2014). In J. Boulton, 100 ideas that changed the web. London, UK: Laurence King. Retrieved from http://search.credoreference.com/content/entry/lkingideas/metadata/0
  8. 8. Metadata – does it matter? • “Metadata is a social (human) construct and reflects its purposes” (Gartner, 2016) • Purpose: find-ability, discover-ability, preserve-ability, render-ability, marketing, selling
  9. 9. What is metadata? Metadata is a human construct Metadata is not found in nature Metadata reflects its purposes (Alemu & Stevens, 2015; Gartner, 2016)
  10. 10. …yes, this is why we have standards
  11. 11. ... we librarians do care about metadata Theory and principles (Paul Otlet, Ranganathan, Melville Dewey, Eugene Garfield) Standards – ISBD, AACR2, RDA, FRBR, Dublin Core, MARC, BIBFRAME Tools – Taxonomies, thesauri, ontologies, classification schemes Principles of sufficiency and necessity, user convenience, representation and standardisation (IFLA, 2009; Svenonius, 2000). S. R. Ranganathan’s five laws
  12. 12. DC (Dublin Core)
  13. 13. Extended DC

  16. 16. What is in a catalogue record?
  17. 17. A MARC Record
  18. 18. Metadata for libraries “Metadata plays a critical role in the function of any discovery service. Search, relevancy ranking, faceted refinement, and recording grouping function (FRBR) all respond to the metadata present.” (Han & Weathers, 2016, p, 275 in Varnum, 2016).
  19. 19. Enriching through RDA (Resource Description & Access)
  20. 20. … enrich then filter
  21. 21. Balancing act: enriching versus quality ‘Useful’ rather than ‘perfect’ metadata Controlled vocabularies: taxonomies, thesauri, ontologies Ontologies afford us to create open & scalable metadata structure Allowing us to incorporate multiple interpretations of things Incorporating multiple access points Ensuring metadata quality
  22. 22. Filtering through FRBR • Grouping related EDITIONS & VERSIONS together • Latest editions displayed first • FRBR requires good metadata • FRBR criteria – matching title and author fields • Authority headings – standardisation and consistency in recording authors
  23. 23. “Information as Thing” (Buckland, 1991)
  24. 24. FRBR – Conceptual model Source: https://www.loc.gov/catdir/cpso/frbreng.pdf • Entities • Relationships • Attributes Source: (Tillett, 2003)

  28. 28. FRBR requires STRUCTURED metadata
  29. 29. FRBR requires CONSISTENT metadata  Selwyn, Norman  Selwyn, NM  Selwyn, Norman M Consistency • With help from Solent’s Digital Library Systems Manager, we changed > 46,000 personal author names according to Library of Congress and British Library name authority lists

Limitations of standards (Coyle, 2010; Coyle & Hillmann, 2007; Lagoze, 2010; Mathes, 2004; Shirky, 2005; Veltman, 2001; Weinberger, 2005, 2007; Wright, 2007; Lehmann, 2010; Andersen & Skouvig, 2006.; Floridi, 2000; Hjorland, 2000)  Growing library collections  Ever changing technologies  Changing users’ expectations  Limitations of contemporary standards-based metadata approaches  The social space of documents is missing (Otlet, 1934)  Lack of openness and scalability issues
  40. 40. The theory of metadata enriching
  41. 41. The theory of metadata enriching & filtering  Separation of metadata content (enriching) and interface (filtering)  Enriching as a continuous process  From user-centred to user-driven metadata enriching and filtering  Metadata diversity better conforming to users’ needs  Seamless linking  ‘Useful’ rather than ‘perfect’ metadata  Post-hoc user-driven filtering
