Search and find metadata in education

  1. 1. Phelim Bradley , Mark Moriarty 2011-08-05 Search and Find: Metadata in Education
  2. 2. Topics we'll cover <ul><li>What we've been doing this year and this summer. </li></ul><ul><li>Meta-Data - what is it? Why have standards? </li></ul><ul><li>Quick overview to most prominent Meta-Data standards. </li></ul><ul><li>Unfortunate lack of sustainability in OER space.  Dried up standards organizations.  Static repositories. </li></ul><ul><li>Not education-specific tools being used. </li></ul>
  3. 3. Who are we? <ul><li>(And what do we know?) </li></ul>
  4. 4. What is metadata? <ul><li>Describe: </li></ul>
  5. 5. The metadata might look like this. Artist                 Leonardo da Vinci Year c. 1503–1519   Type Oil  on  poplar Dimensions 77 cm × 53 cm (30 in × 21 in)   Location   Musée du Louvre , Paris
  6. 6. Or...like this. Creator da Vinci, Leonardo Title Mona Lisa Start Date 1503 End Date 1519 Paint Oil Dimensions Portrait, 4081cm2 Location Musée du Louvre , Paris, France
  7. 7. Standards Artist Surname, Firstname Title Mona Lisa Start Date DD/MM/YYYY End Date DD/MM/YYYY Type Paint type on canvas Dimensions length x width in centimeters Location building, city, country.
  8. 8. Meta-Data for Educational Resources <ul><li>Well, what is an educational resource? </li></ul><ul><li>What defines something as a &quot;learning object&quot;? </li></ul><ul><li>What &quot;high level data&quot; would one want to know about educational resources? </li></ul>
  9. 9. What metadata NOT!  <ul><li>  </li></ul>
  10. 10. Meta-Data for Educational Resources at the moment <ul><li>. </li></ul><ul><li>Two prominent standards are: </li></ul><ul><ul><li>IEEE LOM = Institute of Electrical and Electronic Engineers </li></ul></ul><ul><li>                              Learning Object Meta-Data </li></ul><ul><ul><li>DC = Dublin Core Education </li></ul></ul><ul><li>Individual online repositories / institutions have tweaked these general standards to create custom &quot;application profiles&quot;. </li></ul>
  11. 11. IEEE LOM (Learning Object Meta-Data)
  12. 12. IEEE LOM (Learning Object Meta-Data) <classification> <taxonpath>     <source><langstring>Topics</langstring></source> <taxon>    <id> http://www.research.ibm.com/elearn#webservices </id>    <entry>       <langstring>Web Services</langstring>           </entry> </taxon> </taxonpath> </classification>
  13. 13. IEEE LOM (Learning Object Meta-Data) DON'T PANIC!! !
  14. 14. Publishing Online Content <ul><li>People do what's easy. </li></ul><ul><li>from Wordpress to Wikis to YouTube. Simplicity is key. </li></ul><ul><li>Creative Commons to the rescue! </li></ul>
  15. 15. LRMI &quot;The  Learning Resource Metadata Initiative  is a project co-led by Creative Commons to build a common metadata vocabulary for educational resources.&quot;   http://wiki.creativecommons.org/LRMI http://schema.org/docs/schemas.html
  16. 16. The problem with standards (is that there's so many of them). <ul><li>One standard to rule them all? </li></ul>

  18. 18. Meta-Data <ul><li>~Data about data.  </li></ul><ul><li>Ex . high-level data about a specific file, in this case, a song: </li></ul><ul><li>&quot;ID3v1.. introduced in 1996: By adding a small chunk of extra data in the end of the file one could get the MP3 file to carry information about the audio and not just the audio itself.  &quot; </li></ul>http://www.id3.org/ID3v1 Song Title 30 characters Artist 30 characters Album 30 characters Year 4 characters Comment 30 characters Genre 1 byte
  19. 19. Dublin Core (DC) <ul><li>There are 15 elements  </li></ul><ul><li>that can be described using DC. </li></ul><ul><li>A survey of sites using DC done in 2007 assigned a score of 1 if the field was actually used, and 0 if the field was not used.  </li></ul><ul><li>The average scores for 23 sites are shown. </li></ul><ul><li>“ DC Element usage (Proportion of records with at least one entry) ” source: Miles Efron, Texas - </li></ul><ul><li>Journal of Digital Information , Vol 8, No 2 (2007) </li></ul>

  27. 27. What meta-data do we really need? <ul><li>Meta-data is expensive. </li></ul><ul><li>The meta-data you require depends on your objective... are you searching as a student for notes?  Generally browsing a topic out of interest?  A professor creating a syllabus? </li></ul>
