Discussion

  • CTAB liaison to CACTI
    • Suggestion to have a CTAB liaison to CACTI  (Community Architecture Committee for Trust and Identity) and vice versa

      •           InCommon TAC
      •            CTAB

      • CACTI  meets biweekly on Tuesdays at 11am ET.
    • DECISION:
      • Thanks to Richard Frovarp who volunteered to be the CTAB Liaison to CACTI
      • Richard’s “term” as liaison to CACTI will be until the end of 2022.

Working Group Updates Process

  • Streamlining regularly occurring working group updates - follow TAC’s convention to send updates via email? 
  • Should liaisons put an update in the CTAB scribing doc, instead of having email updates or verbal updates?  
  • DECISION:  liaisons will put updates into the CTAB scribing doc.

Working Group Updates

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.
