    16. 16. Multiple Versions & Formats of 1 learning object !
    17. 17. Using basic section 7 - “relation”
    18. 18. Using basic section 7 - “relation” describes relations between different learning objects not “metadata”
    19. 19. Using basic section 7 - “relation” describes relations between different learning objects IS PART OF not “metadata”
    20. 20. Using basic section 7 - “relation” describes relations between different learning objects IS PART OF not “metadata” would lead to combinatorial explosion of relationships
    21. 21. Using basic section 7 - “relation” describes relations between different learning objects IS PART OF not “metadata” would lead to combinatorial explosion of relationships !
    22. 22. Solutions (?) IMS ILOX - “Information for learning object exchange” Qualify location Qualify location with an identifier service Create Recursive LOM instances
