* [ ] Discussion topics/questions
    * [x] @Parth Patel - GUAC Demo
        * GUAC is a collaboration among Google, Citi, and Kusari
        * Graph for Understanding Artifact Composition
        * Repo: https://github.com/guacsec/guac
        * Status: Pre-Alpha
        * Goal: aggregate supply chain security artifacts to enable policy decisions
        * Collect from Rekor, GCS, Sigstore, GitHub; ingest everything into a graph DB for analysis
            * Automatic ingestion of new artifacts as they materialize
        * DB is a collection of artifact, package nodes with connecting edges
        * queries like:
            * "show me everything that depends on debian version x.y.z"
            * "what are all the dependencies that are missing SBOM/SLSA/vulnz scan/etc."
            * can drill down to the file level
            * walk graph of shared data, shared dependencies
        * goal: make GUAC an open public service for OSS
        * not yet working on integrations to enable policy decisions based on GUAC
        * @bendory This ties back to Supply Chain Maturity:
            * 
    * [x] @Justin Abrahams - How do we rate SBOMs? 
        * Not all SBOMs are created equal. How complete is the SBOM? Does it include package names? Versions? License details?
        * Q: "Is this SBOM actually good?" How valid and complete is the information?
        * Can we create a scorecard?
        * Next step: collect some "in the wild" SBOMs and come up with a scoring mechanism
    * @Omer Gil - Do we have an objective of creating a maturity model?
        * @bendory - Long-term "yes", but we're a long way from there; tools are still being explored and developed. But in the long-term, we would like to see a CD Maturity Model definition broadly adopted in the industry.
* [ ] Action items
    * @Justin Abrahams - Share results from SBOM analysis and scoring brainstorm
    * @Ankit Mohapatra - show differences between SBOM generated by syft and tools like ko (sbom generation at build time).

### October 18, 2022

* [X] Attendees (include affiliation)
    * David Espejo (VMware)
    * Parth Patel (Kusari)
    * Jay White (Microsoft)
    * Terry Cox (Bootstrap)
* [X] Welcome & intros
* [ ] Discussion topics/questions
    * [ ] Goals of this workstream (cont.)
        * [PP] For areas of consideration, include runtime attestation.
        * Guac project: https://github.com/guacsec/guac
        * [JW] Also considerate end-of-life, since we are talking 'lifecycle'
        * [PP] What is the main deliverable from this WG?
        * [TC] Make sure to allign with CDF's Best practices SIG so there's integration as there's potential overlap. How is this information going to be published? Other SIGs using docsy (collaborative docs editing). Happy to facilitate (Previous work: https://bestpractices.cd.foundation/)
        * [JW] S2C Framework is now under OpenSSF
        * [TC] There's got to be a good narrative on business reasons to do this, fill in conceptual gaps so is accesible for people from different levels of maturity in the field. CDF's Best Practices high level section on SSC
* [ ] Action items
    * @Parth Patel to demo Guac in the next meeting

### October 4, 2022

* [X] Attendees (include affiliation)
    * David Espejo (VMware)
    * Ankit D Mohapatra (Berkshire Grey)     
    * David Bendory (Google)    

* [X] Welcome & intros
* [ ] _Add discussion topics/questions_
    * Goals of this workstream.  
        * How to measure quality of CD?
        * Design metrics for CD maturity
        * To have simple to understand 'ladder' of CD adoption, maturity, reliability
        * Augmenting SLSA with another set of metrics, not changing SLSA
        * [AM] Should 'Level 0' be defined as the adoption of any sort of CD practice to begin with? (eg Source Code Management, branching)
        * **Discussion topics for next meeting**:
            * define areas for consideration -> SCM, lifecycle automation, test coverage, presubmit validation, post-submit validation, static analysis, vulnerability analysis, rollout automation, artifact management, deployment management, Canary analysis, production monitoring, SLSA and SBOMs...
            * presentation on what one or more organizations are doing in an area for consideration
