Phew! Back in familiar territory which speaks my language…

Resource creators can be a source by…

  • Tagging – labelling titles and metadata elements (keep to the lingo…)
  • Embedding metadata – inserting meta tags
  • Computers as creators of resource carriers add metadata (eg. file size)


  • Blurb as a form of metadata is generally their responsibility
  • Distribute to retailers and libraries
  • Journal publishers similarly to database providers
  • Now too to search engine providers
  • Digital world means resource creators now less dependent on publishers

Information professionals…

  • Responsible for the provision of effective information retrieval tools
  • All organizations generate information and could be termed information agencies – information architects (thinking The Matrix!) work to improve usability

Library cataloguing…

  • Special form of indexing
  • Cataloguers becoming metadata librarians

Metadata librarianship…

  • Responsibility for a number of retrieval systems including ye olde catalogue
  • Integration of systems by working on interoperability and developing federated search systems

Indexing and abstracting…

  • Professional indexers contribute index terms to databases covering multiple resources and/or index individual resources
  • Database indexing similar to library cataloguers traditional subject indexing – controlled vocabulary used of subject terms (descriptors)
  • Analytic indexes contrast with Table of Contents (also an index) are at the part of the book.( In other words what I understand as simply the Index!)
  • Types of abstracts – indicative (indicate main topics); informative (objective summarising); evaluative or critical (what it’s about and is it worth viewing)

Archival description…

  • As unique materials, usually in-house metadata – not derived from external sources
  • import of thoroughness and accuracy – restricted physical access usually

Museum documentation…

  • Documentation = resource description

Records management…

  • Like an archivist but less focus on historical records
  • Accuracy and thoroughness important = economic damage of lost records

Information architecture…

  • Organisation of information on intranets and websites
  • Concerned with menus, site maps and possibly seartch engines to index metadata

End users…

  • The contribution of Web 2.0 – reviewing, rating, tagging
  • Like the point of “anarchic” rather than “democratic” when it comes to tagging…no one votes but does not frequency indicate something?
  • Marginalia in the modern world through annotating and indexing e-book pages collaboratively
  • Folksonomies – indexing vocabularies generated by end-users


  • Struggle with information content itself
  • Automatic indexing exists re. generating subject terms but problematic – analogy of  “a bag of words”
  • Same same automatic classification – create classifications based on clustering algorithms
  • Knowledge structures generated from manually built controlled vocabularies
  • Automatic summarization more effective with smaller documents
