2. Overview
   Expected delivery
   October 2018
   Recent progress
   ● Incorporating additional use cases in
   the Permission Matrix
   ● Wrapping up Permission Matrix
   Biggest risk
   Transitioning from analysis and
   requirements gathering to technical design
   and implementation

3. Problem We're Solving
   Inflexibility
   ● Current permission
   implementation requires
   downstream developer
   involvement to modify
   ● Vulnerable to upstream
   change
   ● Mixture of "can?" and
   "is_a?" permission checks
   Opacity
   ● Cannot easily answer "Who
   can take the given action
   on the given object"
   ● Mixture of permissions on
   objects vs. in
   configurations

4. Problem We're Solving
   Incomplete Use Cases
   ● Current permission
   implementation no longer
   reflects the more extensive
   permission use cases of the
   community
   Inadequate
   Documentation
   ● Ambiguous how to modify
   my institution's
   permissions in a
   sustainable way

5. Deliverables
   Context Summary
   ● A one page summary of the
   current state of
   permissions in Hyrax
   Requirements
   Gathering
   ● Spreadsheet of submitted
   use cases
   ● Permission matrix to distill
   the use cases into a visual
   format of individual
   permissionable actions

6. Deliverables
   Requirements Synthesis
   ● Documentation of current
   gaps in the existing
   permission system -
   included in Permission
   Matrix and Design
   Objectives
   Design Objectives
   ● An implementation
   allowing repository actions
   to be permissionable and
   configurable
   ● Document listing design
   objectives

7. Process - How We Got Here
   Step 1: Gathered Information
   ● Reviewed Notre Dame’s prior analysis
   ● Discussed variety of problems which we needed to solve
   ● Solicited use cases from organizations participating in working
   group
   ● Gathered use cases in a common spreadsheet format

8. Process - How We Got Here
   Step 2: Organized Information
   ● Distilled common use cases into the Permission Matrix: a
   collection of individual permitted actions in a visual format
   ● Presented Permission Matrix to the community for feedback
   ● Added new actions based on community feedback

9. Process - How We Got Here
   Step 3: Analyzed Information
   ● Identified gaps in the existing permissioning system
   ● Identified objectives for a new permissioning system to be a
   success

10. Next steps
    Undelivered Deliverables
    ● We did not get to the design stage - we realized that our team
    composition lent itself to analysis and use-case gathering, and
    less towards system design
    ● Recommendation: A timeline and supplemental documents from
    which the community to further design out, develop, and
    implement the synthesized requirements.

11. Next steps
    Wrap Up Analysis Working Group
    Final report at Samvera Connect 2018
    Pass the Baton
    Charter a new working group with an eye towards design and
    implementation
    ● Should we do this? What happens if we don't?
    ● Who should (and can) lead this?

13. Question for the Community
    What additional information do you need to make a
    decision as to whether to invest (or not) in designing
    for and implementing these functional
    requirements?
