Working Group Updates Process
- Streamlining regularly occurring working group updates - follow TAC’s convention to send updates via email?

Quarterly Chairs meeting (Chairs of TAC, CACTI, CTAB, with Nicole Roy and Albert)
- Reflections from cross-committee chairs quarterly meeting
- Increased collaboration between CACTI and CTAB
- Discussed strategies for communicating the value of multilateral InCommon federation.
- There are some issues around supporting Shib
- Important to understand federation in a more nuanced way
- Some participants, including some major research institutions, are moving towards a commercial solution
- Some orgs are maintaining federation for a few research services, such as NIH
- Based on a recent email thread, some orgs may move away from seeing InCommon as the solution for streamlined access to SaaS services.
- Hosted solutions for brokering new orgs into InCommon could be seen as a gift
- Kevin: what is the utility of multilateral?
- Publish metadata once, use it many times.
- With SPs rising and falling within a short period of time, discovery can present a challenge and needs a solution like multilateralism.
- Sometimes bilateral SAML relationships are set up and they can be difficult to manage.
- Perhaps we should start to highlight the org to org use case more than, in addition to, the enterprise use case. Need more data
- There is an opportunity, not just a threat from the current trends
- David: in addition to research projects, another use case requiring the same kind of multilateral infrastructure is for scholarship and journal access
- David will share his notes from this Chairs meeting with CTAB
- Please inform David if you would like to join a future Chairs meeting.
- Andy would like to join in the future.
- Looking at providing more data, including trend reports
