  1. 1. GFDC and GFIS Jarmo Saarikko IUFRO 6.03.03 deputy coordinator Fri 2 Dec 2005
  2. 2. The message <ul><li>Future of classifications </li></ul><ul><li>Why GFDC? </li></ul><ul><li>What is GFDC? </li></ul><ul><li>GFDC features </li></ul><ul><li>Implementation of GFDC in GFIS </li></ul>
  3. 3. Future of classifications <ul><li>Keywords cannot ”group” information sources in the same way as classifications do (e.g. ”shelf browsing” for related items) </li></ul><ul><li>The index of the classification provides ”keyword” access or mapping opportunities </li></ul><ul><li>Hierarchical classifications and their auxiliary lists provide support for creating Ontologies and Topic Maps. </li></ul>
  4. 4. Why are we updating the FDC classification? <ul><li>Keywords are easy to use, but not enough due to lack of controlled multilingual vocabularies in Forestry </li></ul><ul><li>Numerical codes are language independent </li></ul><ul><li>Hierarchical classifications ease the way to the semantic web and to </li></ul><ul><ul><ul><li>ISO Topic Maps or </li></ul></ul></ul><ul><ul><ul><li>W3C Ontologies (RDF) </li></ul></ul></ul>
  5. 5. GFDC is <ul><li>a tool for organising and retrieving electronic and paper forest and forestry-related information resources. </li></ul><ul><li>a flexible, multilingual, hierarchical, controlled subject classification. </li></ul>
  6. 6. GFDC is <ul><li>Maintained, enhanced and applied by IUFRO Unit 6.03.03 </li></ul><ul><ul><ul><li>a dynamic, open, user-driven community of individuals involved in forest-related research, </li></ul></ul></ul><ul><ul><ul><li>committed to improving access to forestry and forest-related information </li></ul></ul></ul>
  7. 7. GFDC f eatures <ul><li>Custom designed by forest researchers </li></ul><ul><li>Hierarchical subject divisions </li></ul><ul><li>Standard for the industry </li></ul><ul><li>International (12 languages) </li></ul><ul><li>Developed over 100 years </li></ul><ul><li>The classification provides a browsable, numeric subject hierarchy and an alphabetical subject index. </li></ul>
  8. 8. GFDC implementation in GFIS <ul><li>Suggestions by Jarmo: </li></ul><ul><li>Recommend using classifications in addition to keywords </li></ul><ul><li>Recommend using GFDC as the classification schema for the Dublin Core field ”Subject” </li></ul><ul><li>Provide GFIS browse or search interface with the option using GFDC categories (irrespective of resource type) </li></ul><ul><li>Create aggregated feeds based on selected categories thus providing users a means to track new items in their own science </li></ul>
  9. 9. Technical requirements <ul><li>Implementing Dublin Core ”Subject” field may require using RSS 1.0 (RDF) </li></ul><ul><li>GFIS aggregator should be able to import any kind of RSS or Atom formats as most aggregators and RSS readers already do </li></ul><ul><li>RSS is becoming ubiquitous for delivering metadata on almost anything – many portals are being restructured with a mix of provided and personalized feeds </li></ul><ul><ul><li>e.g. RDF Site Summaries for links to web-pages or shared bookmarks </li></ul></ul>
  10. 10. GFIS possibilities <ul><li>These are personal comments </li></ul><ul><li>Some resources may use the GFDC more efficiently – adds value to include them </li></ul><ul><ul><li>Use any existing RSS feeds of the providers </li></ul></ul><ul><ul><li>Provide the links to original RSS-files on one page (e.g. in a Provider list) </li></ul></ul><ul><ul><li>Create a ping server (to which registered providers announce updates of RSS files) </li></ul></ul>
  11. 11. GFIS possibilities... <ul><li>Consider using Open Archives Initiative Protocol for Metadata Harvesting for searching publications (OAI-PMH) from the Partners’ existing on-line collections </li></ul><ul><li>Consider providing a Topic Map (or an ontology) based interface for searching </li></ul><ul><ul><li>There are already commercial tools for doing this </li></ul></ul><ul><ul><li>Requires subject specialists for designing the topic maps (i.e. defining concepts and their relationships) </li></ul></ul>
