  • 1. JEM Repository for Learning Objects Antti Alamäki Olga Caprotti Matti Pauna University of Helsinki
  • 2. Launched on January 2008 as an integrated service from the JEM Portal http://jem-thematic.net/lom
  • 3. Purpose
  • 4. Metadata
    • Utilizing the current de facto standard: Learning Object Metadata (LOM) by IEEE
      • “ attributes that are needed to adequately describe a learning object and can then be used for automatic processing of learning objects and for their classification ”
    • Specifically designed for educational materials
    • Modified to JEM’s needs (not all fields are used)
  • 5. LOM Data Model
    • LOM metadata descriptions include more than 70 fields in nine categories describing, for example
      • structure and interactivity of the content
      • topic classification
      • school level and difficulty
      • author(s) information
      • file format, software environment, etc..
      • JEM Repository supports a subset of these elements
  • 6. Functionalities
    • Browse contents
    • List view and sort (by classification, title, date, or author)
    • Add record and register content (as a url and also attachment)
    • Edit record
    • Export LOM record to an XML file
  • 7.  
  • 8. Metadata form
    • Fill in the fields for metadata elements
    • Instructions of the purpose of the information are given in the form page
    • Screencast will be made available in the JEM support pages demonstrating metadata editor
  • 9.  
  • 10. Select classification from taxonomy
  • 11. Classifying Contents
    • The classification describes the topics covered for example in a mathematics course as a tree
    • MathTax (also known as LivingTaxonomy) is used as a basis for the JEM classification
    • The LivingTaxonomy project is a community of educators, content publishers, and developers who aim at “creating global, open source, standards-based taxonomies for digital education”
  • 12. Taxonomy (for Single Variable Calculus)
    • Easy to organize contents for fine-grained educational modules
  • 13. Implementation
    • Built as a module for Drupal (open source content management platform) by Antti Alamäki
    • As in Drupal framework, the module is programmed in PHP, using MySQL database
    • Will be made available to the Drupal community
  • 14. The metadata fields can be modified (by administrator)
  • 15. Future plans
    • Reviews and rating
    • Search with metadata form
    • Metadata form template
    • Import from XML
    • Combine with Drupal OAI module for metadata harvesting
    • Support ProLearn Query Language for confederated search engines
