About Project Concordia

Check out the Concordia workshop RSA 2008 notes!

Project Concordia is a global initiative designed to drive interoperability across identity protocols in use today. It does this by soliciting and defining real-world use cases and requirements for the usage of multiple identity protocols together in various deployment scenarios, and encouraging and facilitating the creation of protocol solutions in the appropriate homes for those technologies.

In general, Concordia participants take on new work when a deployer (of any size) presents a problem that existing identity protocols do not solve, ideally a problem that benefits from greater interoperability between protocols. The participants then work with a wide swath of the Internet community to document one or more resulting use cases, requirements, and interop scenarios. All Concordia output is recorded on the wiki. Use cases and requirements may then be used as input to a technical group where relevant specification development occurs. When starting this process, Concordia participants are not biasing themselves by looking at what technical group will ultimately take on the resulting work.

Concordia welcomes participation by representatives of all identity-related initiatives as well as the wider Internet community with an interest in the areas of work the project is undertaking. Note that while Concordia was conceived of by members of the Liberty Alliance, it is organizationally independent and run as an open and self-regulating community.

Meeting Schedule

We meet by phone on some Tuesdays at an hour that splits the difference between two hours in which various people had conflicts:

  • 10:30-11:30am PT (normative across summertime changes)/ 1:30-2:30pm ET / 6:30-7:30pm UK /7:30-8:30pm CET / 5:30-6:30am NZ (next day)

The dial-in number is:

  • US toll-free +1 866 469 3239, caller-paid +1 650 429 3300, code 7860-6951#

Upcoming telecon dates are:

  • June 3...

We are also planning a Policy and Entitlements Management workshop at Catalyst on Monday, June 23. See below for more details and to sign up to participate.

Current Work

We demonstrated technology-provider interop of high-priority scenarios at the RSA conference in April 2008. To do this, we identified scenarios of interest (InfoCard+federation and SAML2+WS-Fed chaining) and fleshed them out. At the December workshop at IIW three scenarios were selected. See the Concordia workshop RSA 2008 notes page for the results of the workshop and ongoing follow up work.

History: We began to prioritize scenario areas at the DIDW workshop (see DIDW Workshop 2007 Notes) -- for example, identity provider discovery is an A-priority issue but single logout interop is only B-priority. Some topics will be interop-tested but other topics are suitable mostly for further deployer education/clarification because they are so broad and/or they involve business decisions that go beyond technical considerations.

We gather input from deployers on an ongoing basis, and deployers have made the following presentations in workshops to date:

We will produce educational writeups/white papers on areas of strong deployer interest that don't lend themselves to easy answers. The first will be:

There is interest in creating a second white paper on the problems of single logout, which share some philosophical similarities to the problems of IdP discovery.

Policy and Entitlements Management

Given successful work thus far identifying and defining end deployer interoperability needs, we are now expanding our work to also look at policy and entitlements management and associated standards, including XACML and WS-Policy. Modelling the successful approach taken thus far in Concordia, the first use case gathering workshop on this will take place MONDAY, June 23, from 10 am -5 pm, at Burton Group's Catalyst Conference. This is a FREE workshop, and you do not have to be registered to attend the full Catalyst conference to participate (but you do need to add your name to the registration list to help keep track of numbers). The interactive session will feature use case and interoperability scenarios presented by representatives from the defense, government and manufacturing sectors. More detail will be added here as it is confirmed. If you are interested in participating in the Policy and Entitlements Management workshop register here.

Metasystem Use Cases

(Here, metasystem is used in the sense of getting individual systems -- normally involving a single homogeneous set of technologies -- to work with each other. The page referred to is old and is not currently being maintained to any degree of quality.) See the Metasystem use cases page for details on the general and specific use-case landscape.

Following are other groups and organizations that Project Concordia can learn from and should coordinate with as appropriate:

  • 3GPP
  • ITU-T FG on IdM (Abbie Barbir has agreed to be the Concordia liaison to ITU-T)
  • Liberty Alliance
  • OpenID Foundation
  • OASIS (Various OASIS TCs)
  • OSIS (we have an agreement to coordinate meetings to reduce overlap and sync up on scenarios to learn from each other)
