Problem Statement

Nearly every online activity is supported by one or more aspects of Identity and Access Management (IAM). This is perhaps especially true in the domains of teaching, learning and research. Since these IAM services are so ubiquitous, it would be best if service developers followed consistent patterns in how they are to be invoked and used. Over the last fourteen years the higher education community has produced an impressive collection of open source components for various identity and access management capabilities. Recently, the community has taken on the challenge of bringing these components together, developing new components to address gaps in coverage and packaging these components into a complementary set of easily installable and configurable services. Consistent, well defined and documented APIs will be critical to the broad adoption of such loosely coupled, but readily integratable IAM services.

The Data Structures and APIs Working Group (WG) has been asked to spell out an overarching conceptual model for IAM interfaces and information objects. To be more than shelf-ware, such a model must be expressed as a set of design principles and conventions such that the resulting data structures and services will form a coherent and comprehensive whole. Leaving this task undone would certainly lead to increased complexity and needless inconsistencies as each IAM component developer team would likely come up with variant solutions to what is actually a common set of API design problems. As an outcome, campuses would find it more difficult to adopt the resulting services and the education and research community would find it more challenging to maintain, support and evolve the IAM services code base and documentation.

Stakeholders, Influencers and Influences

Different audiences will need to be invited to engage on different aspects of this work. It will be important for team members to bring the perspective and represent the interests of at least the following stakeholder groups:

  1. IAM software component designers and developers
  2. Campus IAM and security service providers
  3. Campus integration teams
  4. Application developers

Charter

The TIER Data Structures and APIs Working Group must keep in mind that TIER design and development teams are the first and most important audience for WG deliverables. Those teams will be the ones implementing concrete APIs, using them to integrate component services with each other and with other systems at the adopting campuses. To that end, the WG must establish and maintain effective two-way communication with the design and development teams.

The Working Group must sequence its work in a way that provides the design and development teams with what they need in order to complete their next round of deliverables.

This Working Group is on the critical path for many of the other IAM deliverables. So the challenge for the group will be to balance responsiveness to a variety of stakeholders with a need to be decisive and to maintain forward momentum on WG tasks and issues.

Membership

Membership in the Working Group is open to all interested parties. Members join the Working Group by subscribing to the mailing list, participating in the phone calls, and otherwise actively contributing to the work of the group. The chair of the Working Group is appointed by TIER and is responsible for keeping TIER and InCommon TAC informed regarding Working Group's progress.

Deliverables Timeline

By year end, 2015

By April 2016

Later, to be determined

  • After each release, learn from the experience of TIER development teams what improvements or additions are needed
  • Vet and refine the IAM functional model:
    • Iterate on an inventory of relatively fine-grained IAM functions.
    • Iterate on a comprehensive functional and conceptual model of IAM objects, events and actions.
  • Promote effective use by the application layer of IAM objects, events and actions. In other words, domesticate applications.

Request for Internet2 Assistance:

  • Already completed
    • Creation of a WG Wiki space with details on each of the following:
    • Creation and archiving of a WG mailing list TIER-api@internet2.edu
    • Set up BlueJeans for WG meetings
    • Set up an issue tracking service using JIRA
    • Creation of calendar invitation (Google calendar, Outlook, Office 365)
  • Ongoing assistance
    • Funding to offset time and work being done by external subject matter experts.
    • Propose and send out agendas and meeting reminders
    • Arrange for TIER developers, QA people, and others to allocate some of their time to working together with this WG as specified under "Tasks" above

    • Support the publication, promotion, discoverability and persistence of appropriate WG documents
