TIER Entity Registry Working Group

Charter for Phase I

Problem Description

The ‘glue’ that binds IAM services together is an Entity Registry. Such a Registry facilitates the creation, maintenance, and distribution of person and other subject / entity information across TIER components and other elements of the institutional IT landscape.  It must be capable of receiving, deduplicating, resolving collisions and otherwise grooming this information from authoritative sources and disseminating canonical person and other entity information to downstream services as a data hub or replication source.

The TIER Entity Registry Phase I Working Group is tasked with identifying and documenting the minimum viable requirements for a TIER Registry component and making recommendations to the TIER Community Architecture Planning and Engagement (CAPE) group about the criteria for the adoption of an official TIER Registry component.  This set of recommendations will then be used to guide the relevant API, development and packaging work.

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


Any interested member of the community may participate in the activity of the group.  Members self-select by subscribing to the group mailing list and contributing during group calls and in discussions on the WG mailing list.

Selection of Chair  

Warren Curry is the chair as approved by the TIER Ad Hoc Advisory group .


The group should complete its first version of the following Phase I items no later than April 1, 2016.


Iteration 1 (Monday, February 1 to Friday, March 4, 2016)



Iteration 2 (Monday March 7 to Friday, April 1, 2016)

Phase I Wrap-Up

After completion of the above tasks and deliverables, this Working Group should help draft a charter for a follow-on Phase II Entity Registry Working Group charged with determining a richer set of functionality for the Entity Registry Component of TIER. Phase II work should also identify gaps, document resource needs and outline a roadmap for implementing expanded functionality in future releases of the TIER Entity Registry package.
