The document summarizes the JEM Repository for Learning Objects, which was launched in January 2008 as an integrated service from the JEM Portal. The repository utilizes Learning Object Metadata (LOM) standards to describe educational materials and supports browsing, adding, editing, and classifying learning objects based on taxonomies like MathTax. It was built as a Drupal module by Antti Alamäki and stores LOM metadata in a MySQL database.
JEM Repository for Learning Objects
- 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
- 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
- 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
