Data Structures and APIs Working Group Charter (Draft)

Problem Statement

In teaching, learning and research, nearly every online activity relies on some aspect of Identity and Access Management (IAM).  Developers of IAM services must follow consistent patterns around how those services are to be invoked and used . Over the last decade the higher education community has produced an impressive collection of open source components for identity and access management. Recently there have been efforts to bring these components together, to develop new components to address gaps in coverage and to package the whole into a cohesive set of complementary services. Well defined and documented APIs will be key to being able to deliver loosely coupled but readily integratable IAM services.

This working group on data structures and APIs has been asked to set 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 so that the resulting services will form a coherent and comprehensible whole. The alternative would lead to increased complexity as each component developer team would likely come up with its own solutions to what is actually a common set of API design problems. As a result campuses would find it difficult to adopt such services and the education and research community would find it difficult to maintain and evolve the IAM services code base and documentation.

Stakeholders/Influencers/Influences

Different audiences can impact different aspects of this problem:

  1. Campus integration teams
  2. IAM software package designers and developers
  3. Application developers
  4. Campus IAM and Security service providers
  5. ...

Tasks

The APIs and Schemas Working Group will:

     0. Review and document lessons from directly relevant prior work inside and outside academia. Do this with design and development teams as the first audience.

  1. Recommend a first round set of conventions for API design and data structure development.
  2. Define a process for ongoing effective two-way communication with TIER developers who will deliver the API and those who will use it.
  3. In tandem with the development teams, complement the API definition with a corresponding set of events and messages.
  4. Learn from the experience of TIER development teams what improvements or additions are needed for the next iteration.
  5. Iterate on 1 - 5.
  6. In parallel with the iterations on 1 - 5, define, vet and refine an IAM functional model:
    1. Iterate on an inventory of relatively fine-grained IAM functions.
    2. Iterate on a comprehensive functional and conceptual model of IAM objects, events and actions.
    3. Iterate on documentation of how IAM objects, events and actions can be used by the application layer.
  7. In tandem with the development teams, define and recommend the use of a set of core object schemas that are extensible by design.
  8. ...

 

Membership

Membership in the Working Group is open to all interested parties. (question) Members join the Working Group by subscribing to the mailing list, participating in the phone calls, and otherwise actively engaging in the work of the group.

==> KH NOTE 2015-09-10: This Working Group is on the critical path for many of the other IAM deliverables. The challenge for the group is to balance responsiveness to a variety of perspectives with a need to be decisive and to keep forward momentum on working through tasks and issues.

Perhaps we define a two-tier structure: A core team and an interest group?

Work Products

Each of the Tasks listed under the Charter above result in work products in the form of documentation and guidance. The ordering of the Charter task list defines a sequencing of tasks along three parallel tracks:

  1. Conventions for API and data structures
  2. IAM functonal model
  3. Core object schemas
