Work Group Charter – Attribute Management


(1) WG NAME (and any acronym or abbreviation of the name): The WG name, acronym and abbreviation must not include trademarks not owned by the Organization, or content that is infringing, harmful, or inappropriate.

Attributes in Motion WG (AIMWG)

(2) PURPOSE: Please provide a clear statement of purpose and justification why the proposed WG is necessary.

The goal of this Work Group is to define and publish best practices and collect use cases in the Attribute Management space.  In particular, focusing on the use of attributes across all stakeholders in the Identity Ecosystem including Identity Providers, Service Providers, and Relying Parties.  Exploring and documenting the potential and best practice around the use of an Attribute Broker will also be discussed.

The work expected to encourage cross-organization communication regarding the strategic and technical work in this space.  While creating technical specifications is out of scope for this group, keeping the group members aware of activities in other work groups and organizations will be critical to success going forward.

 (3) SCOPE: Explain the scope and definition of the planned work.

The group will focus on producing white papers, best practice documents, and an on-going report in to the various activities in the attribute management space. 

Specifically, the Work Group will create a set of best practice documents around:

  • The handling of attributes by Identity Providers, Relying Parties, and Service Providers
  • The definition and proposed use for contexts
  • The definition, best use, requirements and criteria of an Attribute Broker

The Work Group will also continue the work started by the Attribute Management Discussion Group to keep the Repository of links to know work in the attribute space up to date, making sure that relevant work from other Kantara Work Groups as well as outside organizations and governments are collected and shared.

The Work Group will explore the concept of an Attribute Broker, defining what an Attribute Broker is, the characteristics of a good attribute broker, and how the use of an Attribute Broker enhances privacy.  This will turn in to a set of use cases, a white paper, and eventually a Best Practices document.

(4) DRAFT TECHNICAL SPECIFICATIONS: List Working Titles of draft Technical Specifications to be produced (if any), projected completion dates, and the Standards Setting Organization(s) to which they will be submitted upon approval by the Membership.

No technical specifications will be created out of this Work Group.
