1. Hierarchy at Oxford Adam Marshall and Matthew Buckett University of Oxford

2. Overview The problem The current solution Solving in Sakai Demo What’s next? Technical guff

3. Sakai at Oxford Current VLE/LMS is Bodington Moving to Sakai –Pilot 08/09 –Production 09/10 –Bodington decommissioned 11/12 Must offer equivalent functionality Big problem: lack of Hierarchy

4. Hierarchy? Reflect University structure Provides context to material Reuse of sites Meaningful URLs Anonymous access –Search engine indexing Devolved administration Bodington supports above.

5. Hierarchy in Sakai Resources tool –File hierarchy –Can collapse some Chuck’s subsite work Ian Boston’s work Internal tool hierarchies (Evaluations)

6. Chucks’ Subsite Lots of small hierarchies Useful for tying courses together Not very invasive But Only presents sites you’re a member of Not browseable from Gateway site No tool support No nice URLs No site reuse 6

7. Chucks Subsites 7

8. Oxford Hierarchy Initial development from Ian Boston One overarching arrangement of sites Sites exist in multiple places in hierarchy Meaningful URLs –Site URLs –Page Aliases Tool Support 8

10. Oxford Hierarchy Demo Movie for backup 10

11. Devolved Admin Why? Small central team Encourage first level of support to local IT Increase self reliance 11

12. Devolved Admins 12 English Admin Site Sue (Admin) Joe (Member) Early Medieval English Site Joe (Manage) Rita (Access) Sue (Admin)

14. Technical Implementation Skin Changes Portal changes Hierarchy API Site Manage changes Sites tool (search) Helpers hurt (brittle). 14

15. Hierarchy Enhancements Hierarchy navigation as a tool in site. Drag and drop interface for management. Other related sites. JCR for storage of tree. Tabs aren’t right for parent nodes, anything better? 15

16. What else is possible? Search downwards from here Different toolset based on position Site template based on position Inheriting permissions (parent realm)? But: Tools should not be hierarchy aware
