Action Item Review

  • Hackfest preparation and updates (Todd)

    • Readout from SF Hackfest (Brian and other attendees)

    • August 24-25, virtual (confirmed)

      • Limited participation last time – teeing up specific action items would be beneficial
      • Will create Google doc for agenda to iterate on over the coming weeks
    • October 3-4, Amsterdam (confirmed - details coming soon)
  • Maturity of software discussion (Jeremy & Bill) - PPT deck

    • Jeremy:  Since we last met, presented to Requirements WG and got favorable response.  Got agreement to incorporate into use cases template. Bill and I walked through a spreadsheet of risks and mitigations.  Important to enterprise development. Incorporated a part of discussion from Identity WG (prioritize features for membership services).
    • Next steps:  Start to develop database some more.  Start to update use case template as well to incorporate risk assessment methodology.
    • Brian:  We did talk about this deck at the Hackfest and many found it useful to walk through what we want to be thinking about when getting ready for 1.0 release.
  • Review Hyperledger Release Taxonomy v0.2 and look at semver (Brian)

    • semver versioning #s have not yet been integrated – will revisit next week.
  • TSC election (Todd)

  • Revise Hyperledger Explorer proposal and bring back to the TSC next week for review/approval. (Chris)

    • Pardha:  made some updates, will circle back with Dan/Chris and then post to wiki for discussion next week.
    • Brian:  At the Hackfest last week, there is a path forward to build on top of initial contribution to be able to talk to both Fabric and STL.

Follow-up on Gerrit migration

  • Brian:  There are some outstanding migration questions.  We’ve moved where repo sits, the core upstream repo is now on gerrit.hyperledger.org.  One aspect to determine is:

    • leverage the mirror of the fabric (and other) repos to GH and let nature take its course
    • leverage the ability to establish a non-GH identity for our project leveraging the <meta> tage configuration supported by Go.
    • Discussion ensued leading to the outcome that the technical community will continue to further iterate on this topic over the mailing list.
    • Arnaud reminded the TSC of the Immersion into Gerrit training done by Ry Jones.
