* No meeting recording, just written updates
* Updates (Dadisi)
    * Working with Jacob Green, John Hopkins OSPO++. He has been promoting "Connected OSPOs". He is looking for Foundation support in the form of projects and problems to solve in the open source community. Goal: We get students to work on CI/CD landscape issues including CDEvents Interoperability.
    * Met with Arun Gupta (CNCF) regarding the connect OSPO effort and partnering with academia to research CI/CD including CDEvents.
    * Reached out to Nithya Ruff (LF Board, Amazon) we agreed to meet just haven't picked a time for the same.
    * I'm still trying to get firm vendor commitment to CDEvents but solid yet.
    * Will be spending time on CDEvent spec next week discussing multi-tenant auth/access concerns
        * Andrea: data model is intended to be minimum required, but URIs can be included in events; one idea is for the URI to be set up with multi-tenant capabilities on that end; there might be a need for CDEvents to at least produce recommendations about how to manage CDEvents in multi-tenant scenarios -- more could be discussed in this area
