  • The lay of the land
    There are 704 IT support staff:
    38 colleges
    6 permanent private halls
    7 Divisions (4 academic)
    193 departments

  • Sakai support
    Small central team (3 people)
    ‘WebLearn’ Service manager; Learning technologist / trainer; Developer
    Each unit has IT support staff (ITSS)
    Each unit has Sakai administrators
    Called ‘Local WebLearn Coordinators’
    Create / setup / manage sites
    First line of support

  • http://www.flickr.com/photos/urtica/333048846/
  • Requirements
    A hierarchy of sites
    Access for ‘large groups’
    Local coordinators have ‘admin’ rights
    Local coordinators can delegate rights
    March 2010
    14
    European Sakai Conference – Valencia - Spain..
  • Local Coordinators Must
    Be able to create new & copy existing sites
    Place and move sites in the hierarchy
    Grant create rights to others
    Have access to all a unit’s sites
    Assign visit rights to:
    .auth, .anon, ‘all staff’, ‘all students’, ….
    Not do anything too dangerous!

  • http://www.flickr.com/photos/matt_hintsa/2585707263/
  • What we did
    Project sites only
    Arranged in hierarchy
    Administration Sites (Cf Admin Workspace)
    One per unit
    Participants have reduced ‘admin’ rights
    Different roles
    Improved ‘Manage Access’ page

  • This is a hard word to spell …

    European Sakai Conference – Valencia - Spain..
  • Implementation
    Used hierarchy service from Evaluations
    Overlay hierarchy over pool of sites
    No inheritance
    Only display sites user can visit
    .auth / .anon sites can be in hierarchy
    Use tabs as ‘breadcrumb trail’
    New ‘hierarchy box’ under ‘tool list’
    New ‘manage box’ under ‘hierarchy box’

    European Sakai Conference – Valencia - Spain..
  • Tools
    Create site
    Bring site (a site can be in > 1 place)
    Arrange (remove, swap)
    Need:
    Move / remove tree
    Copy tree
    ‘Primary location’
    ‘Sync instances’ – same sub-sites everywhere
    March 2010
    25
    European Sakai Conference – Valencia - Spain..
  • Issues
    My Workspace is sidelined
    Users expect inheritance (like our old VLE)
    Users want ‘Search under here’
    ‘Active sites’ list has no context
    Navigation if parent site is not visible
    Can’t actually delete sites
    Since no record is kept: too dangerous!
    March 2010
    26
    European Sakai Conference – Valencia - Spain..
  • Supplementary Tools
    Find sites with ‘and visit’ patch
    ‘Search all my sites’ option
    Grey-out unpublished sites
    Improved access management (see later)
    Administration sites plus tools (see later)

  • http://www.flickr.com/photos/10413717@N08/2804363062/
  • Requirements
    Easy assignment of .auth & .anon: ‘site.visit’
    But prevent dangerous .anon
    LDAP integration
    ‘All Staff’ & ‘All students’: ‘site.visit’
    Find sites (site-browser) tool
    ‘Auto-join’ patch (would be good!)
    Reusable internal & ad-hoc groups (coming)

  • http://www.flickr.com/photos/mikesm/2463776436/
  • Requirements
    Administrator powers but,
    Simpler
    Safer
    Constrained
    Create sites
    Manage hierarchy
    ‘Administrator’ access to unit’s hierarchy
    A second level with less rights
    ‘Auditor’ access
  • How Admin Sites Work
    Are said to manage other sites
    Have three roles:
    Admin (Local WebLearn Coordinators)
    Create sites in unit’s area
    Visit admin site & add others
    Automatically have ‘maintain’ rights is all managed sites
    Member (Lecturers / Administration staff)
    Create sites where maintainer
    Audit (Internal / External auditors)
    Visit and read rights
    Admin Sites have dedicated tool: Site List
  • Creating a Site

  • Management
    We have drafted guidelines
    Users must request ‘Admin Site’
    Sign to say “guidelines have been read”
    We keep public list of Local Coordinators

  • Users Cause Most Problems!
    March 2010
    45
    European Sakai Conference – Valencia - Spain..
  • Common Problems
    Users don’t read guidelines/documentation
    Misunderstandings
    A user gave .anon access to admin site. This made all managed sites .anon too. Whoops!
    Departments don’t formulate a policy
    No coherent approach – confused students
    Too many sub-sites
    Too few sub-sites!
  • In Summary
    Users like what we’ve done
    But old VLE (Bodington) had same features
    Seems to work well
    Lots of user education needed
    Need more tools
    Merging process is very difficult (use Git)
    Sakai 3 – arrgghh!!
  • Let us now gaze into our crystal ball …
