  • Information resources are essentially resources that function, primarily, to inform
  • Information agencies – “memory institutions”!
  • The labelling of a resource as an “information resource” rests ultimately in the view of the describer
  • Information resources are “communication devices” but not necessarily visa versa
  • Looking for transmittance over time – reaccessible/reusable
  • “Knowledge pyramid” equates Bloom’s taxonomy – higher order thinking progression – PYP thinking skills – metacognition the ultimate
  • Generic term “information resource” contain/represent dat – information – knowledge – wisdom
  • Interesting…progression of need/sophistication of processing required
  • Information resources are described for the ultimate purpose of facilitating use
  • Reason for use has an effect on the description
  • Involves describers and recipients significantas
  • Medium of description significant…and the system
  • Data elements refer to info about different aspects of what is being described (content elements eg. subject and language; carrier elements eg. size and physical location
  • Information resource description as a product is metadata (data about data or more specifically, structured data about data)
  • Often metadata characterised by function eg. Haynes, 2004 – resource description; information retrieval; resource management; ownership and authenticity; interoperability
  • Other terminology includes administrative metadata (resource management equivalent) and structural metadata (used to facilitate assemblage and rendering of resources – predominantly digital – for use
  • Haynes’ model – retrieval performance is supported by resource description and information retrieval metadata
  • Metadata facilitating access also referred to as discovery metadata or descripive metadata
  • Metadata supportive of access by indicating how to obtain, whether its worthy to be obtained, and of its existence
  • Can provide overview of a collection through grouping (collocation) or to navigate a single resource
  • Information retrieval systems uses metadata to aid access to collections of information or resource components
  • Metadata elements are the ways of describing information resources
  • Effective metadata involves selecting the elements as well as the right values (words of the title/numbers) to record elements (eg. authors names as Joe Bloggs or J. H. Bloggs) or the element of subject could be recorded as “fauna” or “animals”
  • Values used impact effectiveness of metadata
  • Values needc to be recorded in the appropriate format also to be effective, and compatable with the information retrieval system. A transmission protocol may too be focal
  • Four aspects of metadata 1) elemenrs 2) values 3) format 4) transmission
  • Different elements, values, format, and protocols are effective in differing contexts (users, technology, resources, environmental factors need consideration)
  • In managing metadata it may be obtained from external sources; may need entering into an information retrieval system; may need editing or additions; effectiveness of presentation needs considering; preservation also an issue of management; and cost reduction through exchange mechanisms
  • Metadata creation and management is in flux, although recognises the need for some standardisation and conventionality
  • Part of an information ecology (interaction)
  • Digital resources   (Liu, 2004) greater density; less longevity; less uniqueness; great duplicability; greater mobility and fluidity; great connectivity; greater integration
  • Information resource description part of the field of information organisation or knowledge organisation
  • An index consists of representations of the resource which makes for ease of search rather than searching the resources themselves
  • Tools such as library catalogues, search engines, museum registers are indexes – many based on metadata
  • Content-based indexes -eg. Google
  • Bibliographic control and bibliographic organisation refer to practice of organisation in libraries
