  1. Bodington & Sakai Dr Adam Marshall (adam.marshall AT oucs.ox.ac.uk) Learning Technologies Group, Oxford University & Tetra Collaboration

  2. Tetra Collaboration The Tetra Collaboration will work together on projects that address the needs of education, research, technical infrastructure, service oriented architectures (SOA), federated systems, and application frameworks. Oxford, Cambridge, UHI and Hull (UK). Others welcome: tetraproject.org

  3. Tetra Regular developers meetings Regular Board meetings Will bid for projects, eg, : Bodington tools and services into Sakai Fedora, DSpace & Sakai Content Hosting Identity management (planned) Plus many many more! Anyway …………

  4. Bodington? Odd Name! Nathan Bodington - first VC at Leeds Uni Developed by lecturers at Leeds since 1995 Can be a VLE based on virtual campus metaphor v accessible, quite novel, v flexible Currently used by Oxford, UHI and Leeds See: http://bodington.org/ Podcast: Aggie Booth’s Atlanta 06 keynote (http://tinyurl.com/2ldmny)

  5. Local Installation Re-branded as Pilot service 2003-2004 Production service from 2004 2004: 3411 users, 19464 resources, 614109 hits/week 2005: 4781 users, 33040 resources, 1020362 hits/week 2006: 6790 users, 41317 resources, 1831079 hits/week Med Sci (32%), Life Sci (22%), Humanities (18%) 50% registered Oxford users have logged in most departments and 1/3 colleges on board

  6. What we liked (1) Not course-based fits Oxford model of pick ‘n’ mix societies have rooms (sites) committees too (minutes etc) personal space (MyWeblearn) Open content (google-ability) anyone can view our courses 10,300 indexed resources

  7. What we liked (2) Hierarchy cf files and directories Fine grained access control not roles but specific permissions Flexible groups SRS groups, hidden groups, ad-hoc, … Devolved administration

  8. Hierarchy, Groups and ACL (1) Examples guest lecturer on ‘private’ course wants notes public: deep linking from ‘front page’ research project w/ external members external tutor on course multiple owners / change owners tutor sets up <n> fora and partitions tutees can create protected content in place then open up

  9. Hierarchy, Groups and ACL (2) Medical sciences Students create & manage own resources includes notes, MCQ, links, videos non-sensitive material open to all M.Sc. in e-learning First couple of modules public: ‘taster’ rest are protected

  10. Hierarchy Commentary Very important for Bodington: used for organisation of ‘resources’ (ie, sites and tools) – browsable tree used for organisation of groups used for inheriting permissions (from parent) used for devolved administration ‘nice’ URLs (that get a bit long!)

  11. Groups Commentary Very important for Bodington (!): “resource accessible by these groups” each group can have different rights, eg, read, read and write etc. each resource has an owners group some special groups, eg, anonymous, public, oxford groups protected by ACL, have owners group, groups with read access etc

  12. ACL Commentary Very important for Bodington (!!): people don’t have roles, groups have specific permissions very rich permission set: ‘see’ title of resource / site / tool / group ‘read’ resource / site / tool / group ‘edit’ resource / site / tool / group ‘create’ a site or tool at this point ‘post’ to this discussion forum, …… Bingo! Devolved administration.

  13. Devolved Administration ACL + Groups + Hierarchy = Devolved Administration Relieves burden on central admin Improves user experience

  14. Example Demonstrates: Hierarchy Groups Access control MyWeblearn (cf MyWorksite)

  15. Light relief: A cat in a fez!

  16. The Plan We want Groups, Hierarchy & ACL in Sakai Oxford will be aided and abetted by Cambridge, UHI. Also interest from other SF members

  17. Hierarchy: Matthew Buckett

  18. Groups - http://tinyurl.com/3abohr Highlights 1 Centralised ‘pool’ of floating groups External application with GUI (web service and Java API) ‘MyGroups’ link in MyWorksite, includes ‘favourites’ Metadata: version, title, description, expiry date, notes, source (sis, sakai, fedora. etc.) Hierarchy (strict) + ACL (view, see, edit, manage, etc) inheritance

  19. Groups - http://tinyurl.com/3abohr Highlights 2 Search / browse / favourites (note ACL) Creating: Link / copy existing group Preset ACL profiles (cf Sakai Messages & Forums) Inherit Groups of groups (union) Intersection of groups (intersection) Auto partition (eg, for tutorial) Requesting membership / subscription model: auto, none, moderated Shibboleth: issues specification? how many members & demographics?

  20. Groups: Implementation Stand alone Groups Service Need new Sakai GroupProvider Management interface in Sakai Base on Grouper / GAP/PAGS?
